i'm quite new to Excel VBA and formulas but i need to have a cell with random values on the form that i had created to create like a unique id (I know that there might be chances of getting duplicate numbers but it is slim) to send it to people to fill up a form but the thing is that if im using the RandBetween(00000000,99999999), hiding and unhiding just keep activating the formula which is hard for me to keep track if i were to send this template for others to fill up. So is there any way where when i have the formula and when the user opens the Excel form, it will randomize a 8 digit number and copy and special pasting the value overwriting it to freeze the value.
(Other ways are also gladly welcomed, thanks in advance guys)
I'm not sure what you're actually trying to do here, but if you wanted to generate a random number and store its value in a cell, you can use this code in 'ThisWorkbook' in VBA:
Option Explicit
Const MySheetName As String = "Sheet1" ' Change this to your sheet name
Private Sub Workbook_Open()
' Called every time you open the excel document
Dim myRandNumber As Long
Randomize
myRandNumber = CLng(Rnd() * 999999999) ' CLng converts the floating point number to a long integer
Dim rowNum As Integer
Dim colNum As Integer
rowNum = 3
colNum = 5
ThisWorkbook.Sheets(MySheetName).Cells(rowNum, colNum).Value = myRandNumber
End Sub
If you wanted to make sure this number was unique, which is probably what you really want to do, you can store these values in a separate hidden sheet and check these values each time you want to generate a new number.
You could also just timestamp the number using this line of code instead of the random number:
ThisWorkbook.Sheets(MySheetName).Cells(rowNum, colNum).Value = CDbl(Now() * 100000)
This will create a new unique number every 1 second, based on the system time.
If I understand correctly, you want to generate this number once. There are a couple ways I can think of to do this:
Generate the number only if the cell is blank
Set a flag in a hidden sheet
In both cases, if you wanted to generate the number again, you just need to clear the cell containing the number (option 1) or clear the flag in the sheet (option 2)
Option 1 can be done by replacing this part of the above code:
ThisWorkbook.Sheets(MySheetName).Cells(rowNum, colNum).Value = myRandNumber
with this:
With ThisWorkbook.Sheets(MySheetName).Cells(rowNum, colNum)
If (.Value = "") Then
.Value = myRandNumber
End If
End With
Hope this helps

I have a list of serial numbers with a prefix, and then a few numbers. All serial numbers are 8 characters, so depending on the prefix and amount of zeros, different amounts of leading zeros are added between the prefix and numbers. (ex. ALT00001, CAT00564, AAR19470, M0000003, MISC7859, MISC0025)
How can I remove all leading zeros from the Serial Numbers, but keep any zeros that are part of the actual number?
I would love to create a macro that does this, as I would have to run this code on multiple workbooks countless times a day.
With data in column A, in B1 enter:
=LEFT(A1,3) & --RIGHT(A1,5)
and copy downwards.
EDIT#1:
Based on the updated examples, we must find the position of the first numeral in the string and parse based on that.
In C1 enter:
=MIN(FIND({"0","1","2","3","4","5","6","7","8","9"},UPPER(A1)&"0123456789"))
and copy downwards. (this give the position of the first numeral)
Now in B1 enter:
=LEFT(A1,C1-1) & --RIGHT(A1,8-C1+1)
or:
=LEFT(A1,C1-1) & --RIGHT(A1,9-C1)
(if you don't want the "helper" column, combine the formulas)
EDIT#2:
Here is some code:
Sub Deb()
Dim Kolumn As String, rng As Range, cell As Range, s As String, L As Long
Dim i As Long
Kolumn = "A"
Set rng = Intersect(Columns(Kolumn).EntireColumn, ActiveSheet.UsedRange).Offset(1, 0).Cells
For Each cell In rng
s = cell.Value
If s = "" Then Exit Sub
L = Len(s)
For i = 1 To L
If IsNumeric(Mid(s, i, 1)) Then
GoTo Process
End If
Next i
MsgBox "bad data " & s
Exit Sub
Process:
cell.Value = Left(s, i + -1) & CLng(Mid(s, i))
Next cell
End Sub
EDIT#3:
Macros are very easy to install and use:
ALT-F11 brings up the VBE window
ALT-I
ALT-M opens a fresh module
paste the stuff in and close the VBE window
If you save the workbook, the macro will be saved with it.
If you are using a version of Excel later then 2003, you must save
the file as .xlsm rather than .xlsx
To remove the macro:
bring up the VBE window as above
clear the code out
close the VBE window
To use the macro from the Excel window:
Select the worksheet you want the macro to run on
ALT-F8
Select the macro
Touch RUN

I have two approaches, one is using excel array formula to find the numerical value in the text string, and the other is using excel power query to transform the data in 4 simple steps.
Approach 1 - Array Formula
The following formula will firstly convert the text string to array, eg. ALT00001 will become {"A";"L";"T";"0";"0";"0";"0";"1"}, then examine each character in the array if it is a numerical value like this {FALSE;FALSE;FALSE;TRUE;TRUE;TRUE;TRUE;TRUE}, and lastly sum up all the TRUE results. This will give you the total number of numerical values in the text string.
{=SUM(--ISNUMBER(--MID(A1,ROW(INDIRECT("1:"&LEN(A1))),1)))}
Please note this is an array formula so you need to press CSE (Ctrl+Shift+Enter) upon finishing editing the formula.
In my workings, I entered the array formula in Cell B1, then in Cell C1 I entered the following formula to get the result.
=LEFT(A1,8-B1)&--RIGHT(A1,B1)
You can combine these two formulas but it will look awkwardly long and not so easy to interpret by others. If you do combine, you need to press CSE to make it work as it incorporates an array.
Approach 2 - Power Query
Although #Deb did not ask for a solution using Power Query (PQ), I still want to share an alternative way of solving the issue efficiently, given that the above formula-based solution is not so straight forward and somehow complicated.
PQ is able to transform data from multiple worksheets and have ample built-in functions that is quite user friendly. Please note you need to have Excel 2010 or later versions to be able to use PQ.
So here are the steps using PQ:
1) Load the data range to PQ Editor, one way of doing that is to highlight the data range and use From Table in the Data tab as shown below:
2) Once loaded, the PQ Editor will be opened in a new window. The next step is to separate the value into Text string and Numerical string. A quick way of doing that is to use the Split Column (By Non-digit to Digit) in the Transform tab of the PQ Editor as shown below.
3) Now we have the text in the first column and the number in the second column. Next step is to clear the "0" in front of the values in the number column. One way of doing that is to change the Data Type from Text to Whole Number, and then change it back to Text (I will explain why you need to change it back to Text in the next step).
4) Next step is to combine the two columns to get the desired result. One way of doing that is to add a custom column and use & to combine the values from the two columns as shown below.
=[Column1.1]&[Column1.2] the way of using & is same as in an excel formula
As mentioned in my last step, we need to change the number value back to text, the reason is that PQ Editor does not allow combining a text value with a numerical value, it will lead to the following error.
5) The last step will vary depends on your preference. What I did is to remove other columns and load the Result column to the current worksheet where your original data sits.
Unfortunately PQ could not over write source data. However in my opinion it is better to keep your source data somewhere safe without being overwritten, and export your edited/transformed data to a new place and work on it instead.
Here are the codes behind the scene but all steps are performed using the built-in functions which you can google the know-how of each of them easily.
let
Source = Excel.CurrentWorkbook(){[Name="Table1"]}[Content],
#"Split Column by Character Transition" = Table.SplitColumn(Source, "Column1", Splitter.SplitTextByCharacterTransition((c) => not List.Contains({"0".."9"}, c), {"0".."9"}), {"Column1.1", "Column1.2"}),
#"Changed Type1" = Table.TransformColumnTypes(#"Split Column by Character Transition",{{"Column1.2", Int64.Type}}),
#"Changed Type2" = Table.TransformColumnTypes(#"Changed Type1",{{"Column1.2", type text}}),
#"Added Custom" = Table.AddColumn(#"Changed Type2", "Result", each [Column1.1]&[Column1.2]),
#"Removed Other Columns" = Table.SelectColumns(#"Added Custom",{"Result"})
in
#"Removed Other Columns"
Cheers :)
I am working on VBA macro, manipulating data on an excel sheet. I have closes of stocks and need to make a collection of EMA (exponential moving average) series. I need to iterate the same couple of formulas over 100 times, but respective to the cells. For example, the first iteration will be =AVERAGE(D153:D164) , then immediately beneath that will be =(2/13)*D165+(11/13)*E164, which will be format copied down (I'll do that). I need to perform these calculations every 70 rows, ending with =AVERAGE(D8973:D8984) & (2/13)*D8985+(11/13)*E8984. Can someone help me derive a functioning macro? Your help is sincerely appreciated.
EDIT: To be more specific, I need to pass the row number as a variable to use in the formulas. If I see how to do so with one variable, I can use that as a foundation. The above 2 formulae are models, yet each instance of each formula will be unique.
Again, thank You.
Assuming the first formulas are the same, and you are always incrementing the same number of rows (70), this code should work. You can change some of my initial assumptions such as the starting cell, number of iterations, etc.
Sub EMAmakeAFunction()
'''''These can be changed as you need
Dim numberOrRowsToSkip As Integer: numberOFRowsToSkip = 70
Dim TrialsToExecute As Integer: TrialsToExecute = 1000
Dim firstFormula As Range: Set firstFormula = Range("D165")
Dim secondFormula As Range: Set secondFormula = Range("D166")
''''Rest of code should be pretty stable of above assumptions are correct.
Dim i As Integer
For i = 1 To TrialsToExecute
firstFormula.Offset(i * numberOFRowsToSkip).FormulaR1C1 = _
firstFormula.FormulaR1C1
secondFormula.Offset(i * numberOFRowsToSkip).FormulaR1C1 = _
secondFormula.FormulaR1C1
Next i
End Sub
After several hours of research, I still can't solve what seems to be a pretty simple issue. I'm new to VBA, so I will be as specific as possible in my question.
I'm working with a DDE link to get stock quotes. I have managed to work out most of the table, but I need a VBA to create a finished formula (i.e., without cell referencing) in order to the DDE link to work properly.
My first code is as follows:
Sub Create_Formulas()
Range("J1").Formula = "=Trade|Strike!" & Range("A1").Value
End Sub
Where J2 is the blank cell and A2 contains the stock ticker. It works fine, but when I try to fill out the rows 2 and bellow, it still uses A1 as a static value.
Sub Create_Formulas()
Dim test As Variant
ticker = Range("A1").Value
'Test to make variable change with each row
'Range("J1:J35").Formula = "=Trade|Strike!" & Range("A1:A35").Value
'not working
Range("J1:J35").Formula = "=Trade|Strike!" & ticker
'not working
End Sub
I couldn't find a way to solve that, and now I'm out of search queries to use, so I'm only opening a new topic after running out of ways to sort it by myself. Sorry if it is too simple.
You are referencing absolute cell adresses here. Like you would do when using $A$1 in a normal excel formula.
What you want to do is:
Dim row as Integer
For row = 1 to 35
Cells(row,10).Formula = "=Trade|Strike!" & Cells(row,1).Value
Next row
This will fill the range J1 to J35 with the formula. Since (row,10) indicates the intersection of row and column 10 (J)
Firstly, in your second set of code, you define a variable "test", but never give it a value.
You assign a value to the variable "ticker", and then never reference it.
Secondly, the value you have assigned to ticker is a static value, and will not change when it is entered in a different row.
Thirdly, I think your issue could be solved with a formula in Excel rather than VBA.
The "INDIRECT" function can be quite useful in situations like this.
Try inserting the formula
=INDIRECT("'Trade|Strike'!"&A1)
into cell A1, then copy down.
Note the ' ' marks around "Trade|Strike". This is Excels syntax for referencing other sheets.
I'm having some issues with an insheet function that I am writing in VBA for Excel. What I eventually am trying to achieve is an excel function which is called from within a cell on your worksheet, that outputs a range of data points underneath the cell from which it is called (like the excel function =BDP() of financial data provider Bloomberg). I cannot specify the output range beforehand because I don't know how many data points it is going to output.
The issue seems to be that excel does not allow you to edit cells on a sheet from within a function, apart from the cell from which the function is called.
I have created a simple program to isolate the problem, for the sake of this question.
The following function, when called from within an excel sheet via =test(10), should produce a list of integers from 1 to 10 underneath the cell from which it is called.
Function test(number As Integer)
For i = 1 To number
Application.Caller.Offset(i, 0) = i
Next i
End Function
The code is very simple, yet nothing happens on the worksheet from which this formula is called (except a #Value error sometimes). I have tried several other specifications of the code, like for instance:
Function test(number As Integer)
Dim tempRange As Range
Set tempRange = Worksheets("Sheet1").Range(Application.Caller.Address)
For i = 1 To number
tempRange.Offset(i, 0) = i
Next i
End Function
Strangely enough, in this last piece of code, the command "debug.print tempRange.address" does print out the address from which the function is called.
The problem seems to be updating values on the worksheet from within an insheet function. Could anybody please give some guidance as to whether it is possible to achieve this via a different method?
Thanks a lot, J
User defined functions are only allowed to alter the values of the cells they are entered into, because Excel's calculation method is built on that assumption.
Methods of bypassing this limitation usually involve scary things like caching the results and locations you want to change and then rewriting them in an after calculate event, whilst taking care of any possible circularity or infinite loops.
The simplest solution is to enter a multi-cell array formula into more cells than you will ever need.
But if you really need to do this I would recommend looking at Govert's Excel DNA which has some array resizer function.
Resizing Excel UDF results
Consider:
Public Function test(number As Integer)
Dim i As Long, ary()
ReDim ary(1 To number, 1 To 1)
For i = 1 To number
ary(i, 1) = i
Next i
test = ary
End Function
Select a block of cells (in this case from C1 through C10), and array enter:
=test(10)
Array formulas must be entered with Ctrl + Shift + Enter rather than just the Enter key.
The following is the result of downloading information from an accounting system. Basically, I was tasked with sorting through expenses from this year from an online system; once the information was downloaded from the online system, it was not formatted as a spreadsheet (so I couldn't easily use a simple lookup). The information was downloaded as a spreadsheet, however it didn't contain check numbers or names; excel formatted those away for some reason. The only thing that was left is the long stringy document, where each item in the PDF downloaded (which contained check numbers and names) was placed in column 1 (see picture 1), whereas it should have been placed in something formatted like picture 2. Obviously though PDF's do not maintain formatting.
So baring some way that I can transfer the PDF to a workbook and run an analysis (IE through copy paste or save as) I needed to get information from this long stringy thing (it's at 9000 rows at the moment, added in an excerpt).
First, this code sets the worksheet pers as a worksheet, gets the length of data in pers (example in picture 2), and length of data in expensesheet (example in picture 1)
Then it scans pers for items (prior to writing this code items were added manually - such as in the case of picture 2, 'supply 1' and corresponding information that can help denote supply 1, ie invoice #, description, date cut, and so on).
For each of those items, it then scans the "expense sheet". It tries to match the invoice number (which is the closest thing to a unique ID in this case) to the value in cell i, 1; if it exists, it then scans 'upwards' until it finds a long enough string so that it can be the 5 unit string; the one that contains a date, a check number, an amount, and a name, as well as a batch number and a memo.
Once it finds that string, it then splits it into an array, and then seeks to place it in the corresponding cells to the right of that row in worksheet pers.
Issues:
1) I keep receiving an error 400. Normally when I receive an error VBA shows what line. What is this? How can I set up an error catching block so that the editor will provide me more details on the error (ie place it occurred, reason for occurrence, etc)
2) I'm assuming that the long row (in this case its 12th from the top) can only be identified through its length. Is there a better way to identify the long row? Perhaps if it contains multiple dashes?
3) Does anyone know of a way to easily transfer a PDF of an accounting printout so that it retains its formatting when saved or copied to a spreadsheet?
4) Is there a way that this spreadsheet could be easily formatted through excel so that it can more adequately fit into the proper mold (more like picture 2)?
Option Explicit
Sub findDetailMemo()
Dim pers As Worksheet
Set pers = ThisWorkbook.Sheets("PERS")
Dim persLength As Long
persLength = pers.Range("a1").End(xlDown).Row
Dim expenseLength As Long
expenseLength = Range("a1").End(xlDown).Row
Dim currentDetail() As String
Dim i As Long
Dim j As Long
Dim k As Long
Dim tempInt As Long
'first scan all of the items in the pers unit
For k = 2 To 10
'next scan all of the expenses
For i = 2 To expenseLength
'if the invoice # is found
If InStr(Cells(i, 1), pers.Range("a1").Offset(k, 3)) <> 0 Then
'scan upwards; make sure you don't scan beyond the range of the spreadsheet
For j = i To 1 Step -1
'if the scan upwards finds a string that is 80 characters or more
If Len(Cells(i - j, 1)) >= 80 Then
'split it at the -
currentDetail = Split(Cells(i - j, 1), "-", -1, vbTextCompare)
'add it to the pers sheet
pers.Range("a1").Offset(k, 11) = currentDetail(0)
pers.Range("a1").Offset(k, 12) = currentDetail(1)
pers.Range("a1").Offset(k, 13) = currentDetail(2)
pers.Range("a1").Offset(k, 14) = currentDetail(3)
Exit For
End If
Next j
Exit For
Else
End If
Next i
Next k
End Sub
EDIT: After a discussion through the chat lobby, bdpolinsky and I found what was throwing the original error 400 (which was actually error 1004).
The first issue we fixed was the InStr() and Split() functions were referencing Cell objects instead of the string within them. This was fixed by simply adding Cells().Text where strings were required.
On the line If Len(Cells(i - j, 1).Text) >= 80, we discovered that Cells() wasn't referencing the correct worksheet. The fix for this was to define Cells() as pers.Cells(), which is the worksheet the information was imported to. Happy to report that the problem bdpolinsky was having has been solved (as far as the errors go).
The following is from the original answer:
1) At the start of your code (first executable line) you can press F8 to step through the code 1 line at a time until the error is flagged.
You can also use error handlers to catch an error and have excel do something different than default. Error Handling
Sub SomeCode()
Dim i As Integer
On Error GoTo ErrHandler
i = 1/0
ErrHandler:
MsgBox "Error Description: " & Err.Description
End Sub
You can also click next to a line of code to add a Break. Breaks look like red circles, and color that line of code red. Your code will stop when it reaches this line.
2)If Len(cellThatYoureChecking) > 20 Then Code
Or
If InStr(cellThatYoureChecking, "symbolYouWantToFind") <> 0 Then Code
Or visit this post about defining how many times a character is in a string with a function. You could then make your If statement based on the number of times it occurs.
3) This part is poor form for StackOverflow, but what you're asking is a little involved so see if this tutorial is of use to you. Import table from PDF to Excel.
4) The short answer to this is yes. There are a lot of ways to reorganize data in Excel. This question is a little too broad though, and it'd be more efficient to get questions 1-3 answered first before getting too ahead of ourselves.
