I want to calculate the average of the cells in column E, only for the rows that have 0 in column I. It needs an if condition and then perform the standard average line of code.. I am providing the code I have written to calculate the average for all cells in column E. This code needs editing to include this if condtion. If someone knows what to add to have this if condition I would appreciate it !
Also, I am providing a screenshot
lastrow = Cells(Rows.Count, "D").End(xlUp).Row
Range("C1").Formula = "=AVERAGE(E2:E" & lastrow & ")"
formula:
=AVERAGEIF(I:I,0,E:E)
or in vba:
WorksheetFunction.AverageIf(Range("I:I"), 0, Range("E:E"))
As far as I know you cannot do this with an excel function unless you make it an array function. Array functions are powerful but can be very slow at calculating. Here is a VBA solution using a VBA collection.
The answer you selected is definitely a more efficient way of getting the answer. But this code may be useful if you are wanting to manipulate those numbers in other ways since it puts them into a collection.
I made a VBA collection and added to it all values in E that corresponded to 0 values in D. Then I summed it into a variable called f and then divided it by the count of the collection. Then dropped it in the range you wanted.
Sub test()
Dim a As Collection
Dim lastrow As Integer
Set a = New Collection
lastrow = Cells(Rows.Count, "D").End(xlUp).Row
For x = 1 To lastrow
If Cells(x, 9) = 0 Then
y = Cells(x, 5).Value
a.Add (y)
End If
Next x
For Z = 1 To a.Count
f = a.Item(Z) + f
Next Z
Range("C1").Value = (f / a.Count)
End Sub

I'm trying to develop a 'for loop' macro that will calculate the duration between two dates in adjacent columns.
My current code:
Sub Enter_Formulas()
FinalRow = Cells(Rows.Count, 2).End(xlUp).Row 'Counts # of rows in the data set
For x = 5 To FinalRow
Cells(x, 10).Formula = "=I5-H5"
End Sub
This will accurately return the difference between I5 & H5, but I want the formula to flow down the columns. (i.e. the next row should calculate I6 - H6 and then I7-I8.. and so on and so forth)
Any advice would be greatly appreciated!!
I recommend not using a loop, you can autofill the whole range in one go:
Sub Enter_Formulas()
FinalRow = Cells(Rows.Count, 2).End(xlUp).Row 'Counts # of rows in the data set
Range(Cells(5, 10).address, Cells(FinalRow, 10).address).Formula = "=I5-H5"
End Sub
However, if you must use a loop then try this:
For x = 5 to FinalRow
Cells(x,10).Formula = "=" & Cells(x,9).Address & "-" & Cells(x,8).Address
Next x
That way by concatenating cell addresses relying on x, they will also increment by one row each time.
You can also do this, if you must use a loop (and I usually would not), by using the R1C1 form of addressing:
For X = 5 To FinalRow
Cells(X, 10).FormulaR1C1 = "=RC[-1]-RC[-2]"
Next X
And if your worksheet is using the A1 reference style, this will get translated appropriately.
I am new to VBA and am trying to create a report template for work. I also want to see how this would be coded for my own personal understanding instead of using a formula.
Put simply I have a variable set of values in column A and dates in column B. Column D is a variable range of dates (user input. I would like to have this as an array within my code.)
I would like to sum column A while excluding the dates specified in column D, and have this sum output into cell G1. I have attached a picture below.
Thanks in advance!
Picture of the sheet
Try out this code, this is self explanatory.
Sub sumVariables()
Dim i As Long, j As Long, sum As Long, match As Boolean
sum = 0
match = False
For i = 2 To Cells(Rows.Count, 1).End(xlUp).Row
For j = 2 To Cells(Rows.Count, 4).End(xlUp).Row
If Cells(i, 2) = Cells(j, 4) Then
match = True
End If
Next j
If match = False Then
sum = sum + Cells(i, 1)
End If
match = False
Next i
Cells(1, 7) = sum
End Sub
This code would work for n number of rows in your sheet and give the total in G1. Let me know if you need any help.
Just started a new job. I'm automating a month-end report and I'm new at VBA. Been googling most of my issues with success, but I've finally run into a wall. In essence I'm downloading some data from SAP and from there I need to build a report.
My question is: How to do a sumif function using loops in VBA?
Data pull:
Sheet1 contains a product code and purchase amounts (columns A & B) respectively. One product code can have several purchases (several rows with the same product code).
Steps so far:
I arranged the data sheet1 to be in ascending order.
Copied unique values for the product codes onto another sheet (sheet2). So Sheet2 has a list of all the products (in ascending order).
I want to get the sum of all purchases in sheet2 column B (per product code). I know how to do this using formulas, but I need to automate this as much as possible. (+ I'm genuinely interested in figuring this out)
This is what I did in VBA so far:
Sub Macro_test()
Dim tb As Worksheet
Dim tb2 As Worksheet
Dim x As Integer
Dim y As Integer
Dim lrow As Long
Set tb = Sheets("sheet1")
Set tb2 = Sheets("sheet2")
lrow = tb.Cells(Rows.Count, "A").End(xlUp).Row
For x = 2 To lrow
For y = 2 To lrow
If tb2.Cells(x, 1).Value = tb.Cells(y, 1).Value Then
tb2.Cells(x, 2).Value = tb.Cells(y, 2).Value
End If
Next y
Next x
End Sub
If i'm not mistaken, for each product_code in sheet2 col A, I'm looping through all the product codes in sheet1 and getting back the LAST value it finds, instead of the sum of all values... I understand why it doesn't work, I just don't know how to fix it.
Any help would be much appreciated. Thanks!
This statement overwrites the value of tb2.Cells(x, 2).Value at each iteration:
tb2.Cells(x, 2).Value = tb.Cells(y, 2).Value
Instead, I think you need to keep adding to it:
tb2.Cells(x, 2).Value = tb2.Cells(x, 2).Value + tb.Cells(y, 2).Value
But I don't like the looks of your double-loop which uses only one lrow variable to represent the "last row" on the two different worksheets, that could be causing some issues.
Or, in your loop do something like this which I think will avoid the duplicate sum. Still, assumes the second worksheet doesn't initially have any value in
' Base our lRow on Sheet2, we don't care how many rows in Sheet1.
lrow = tb2.Cells(tb2.Rows.Count, 1).End(xlUp).Row
Dim cl as Range
Set cl = tb.Cells(2,1) 'Our initial cell value / ID
For x = 2 to lRow '## Look the rows on Sheet 2
'## Check if the cell on Sheet1 == cell on Sheet2
While cl.Value = tb2.Cells(x,1).Value
'## Add cl.Value t- the tb2 cell:
tb2.Cells(x, 2).Value = tb2.Cells(x, 2).Value + cl.Offset(0,1).Value
Set cl = cl.Offset(1) '## Reassign to the next Row
Wend
Next
But it would be better to omit the double-loop and simply use VBA to do 1 of the following:
1. Insert The Formula:
(See Scott Holtzman's answer).
This approach is better for lots of reasons, not the least of which is that the WorksheetFunction is optimized already, so it should arguably perform better though on a small dataset the difference in runtime will be negligible. The other reason is that it's stupid to reinvent the wheel unless you have a very good justification for doing so, so in this case, why write your own version of code that accomplishes what the built-in SumIf already does and is specifically designed to do?
This approach is also ideal if the reference data may change, as the cell formulas will automatically recalculate based on the data in Sheet1.
2. Evaluate the formula & replace with values only:
If you prefer not to retain the formula, then a simple Value assignment can remove the formula but retain the results:
With .Range(.Range("B2"), .Range("A2").End(xlDown).Offset(, 1))
.FormulaR1C1 = "=SUMIF(Sheet1!C[-1]:C[-1],RC[-1],Sheet1!C:C)"
.Value = .Value 'This line gets rid of the formula but retains the values
End With
Use this approach if you will be removing Sheet1, as removing the referents will break the formula on Sheet2, or if you otherwise want the Sheet2 to be a "snapshot" instead of a dynamic summation.
If you really need this automated, take advantage of VBA to place the formula for you. It's very quick and easy using R1C1 notation.
Complete code (tested):
Dim tb As Worksheet
Dim tb2 As Worksheet
Set tb = Sheets("sheet1")
Set tb2 = Sheets("sheet2")
Dim lrow As Long
lrow = tb.Cells(tb.Rows.Count, 1).End(xlUp).Row
tb.Range("A2:A" & lrow).Copy tb2.Range("A2")
With tb2
.Range("A2").CurrentRegion.RemoveDuplicates 1
With .Range(.Range("B2"), .Range("A2").End(xlDown).Offset(, 1))
.FormulaR1C1 = "=SUMIF(Sheet1!C[-1]:C[-1],RC[-1],Sheet1!C:C)"
End With
End With
Note that with R1C1 notation the C and R are not referring to column or row letters . Rather they are the column and row offsets from the place where the formula is stored on the specific worksheet. In this case Sheet!C[-1] refers to the entire A column of sheet one, since the formula is entered into column B of sheet 2.
I wrote a neat little algorithm (if you can call it that) that does what you want them spits out grouped by totals into another sheet. Basically it loops through the first section to get unique names/labels and stores them into an array. Then it iterates through that array and adds up values if the current iteration matches what the current iteration of the nested loop position.
Private Sub that()
Dim this As Variant
Dim that(9, 1) As String
Dim rowC As Long
Dim colC As Long
this = ThisWorkbook.Sheets("Sheet4").UsedRange
rowC = ThisWorkbook.Sheets("Sheet4").UsedRange.Rows.Count
colC = ThisWorkbook.Sheets("Sheet4").UsedRange.Columns.Count
Dim thisname As String
Dim i As Long
Dim y As Long
Dim x As Long
For i = LBound(this, 1) To UBound(this, 1)
thisname = this(i, 1)
For x = LBound(that, 1) To UBound(that, 1)
If thisname = that(x, 0) Then
Exit For
ElseIf thisname <> that(x, 0) And that(x, 0) = vbNullString Then
that(x, 0) = thisname
Exit For
End If
Next x
Next i
For i = LBound(that, 1) To UBound(that, 1)
thisname = that(i, 0)
For j = LBound(this, 1) To UBound(this, 1)
If this(j, 1) = thisname Then
thisvalue = thisvalue + this(j, 2)
End If
Next j
that(i, 1) = thisvalue
thisvalue = 0
Next i
ThisWorkbook.Sheets("sheet5").Range(ThisWorkbook.Sheets("Sheet5").Cells(1, 1), ThisWorkbook.Sheets("Sheet5").Cells(rowC, colC)).Value2 = that
End Sub
Yay arrays
Is there a way to check if all cells in a column are less than 1? If there were only a few cells, with the number of cells known up front, I would use the code below.
However, from case to case the number of cells in column A will vary. I need to know if any of the cells in column A is less than 1.
If there is one (or more) cell containing a value less than 1, I need a cell (A1 for example) to show NOT OK. If only ALL the cells' values are greater than 1, I need the cell (A1 for example) to show OK.
If all cells in column A have values greater than 1, I want to continue and check column B for the same thing. Otherwise I want to save and close the workbook and continue with next open workbook...also with vba code.
Any suggestions on how to write this in VBA? Maybe there is way other than If(AND...)?
Sub IfAnd()
IF(AND(A5>1,A4>1,A3>1,A2>1),"OK", "NOT OK")
End Sub
This code will solve all your columns and insert the data in THE FIRST ROW OF EACH COLUMN
Sub Problems()
Dim CurCol, LastRow, LastCol as Long
LastCol = Cells(2, Columns.Count).End(xlToLeft).Column
For CurCol = 1 to LastCol
LastRow = Cells(Rows.Count, CurCol).End(xlUp).Row
If WorksheetFunction.Min(Range(Cells(2, CurCol), Cells(LastRow, CurCol))) < 1 Then
Cells(1, CurCol).Value = "NOT OK"
Else
Cells(1, CurCol).Value = "OK"
End If
Next CurCol
End Sub
Here is a way of doing it without any worksheet functions.
Sub test()
Dim ws As Worksheet
Dim ce As Range
Dim sr, lr, lc As Integer
'worksheet you are working with
Set ws = ThisWorkbook.Sheets(1)
'column you are searching
Set ce = ws.Cells(ws.Rows.Count, 1)
'start row set to 2 so row 1 will contain output
Let sr = 2
'search only the last row
Let lr = ce.End(xlUp).Row
Let lc = ws.Cells(sr, ws.Columns.Count).End(xlToLeft).Column
For c = 1 To lc
For r = sr To lr
If ws.Cells(r, c).Value < 1 Then
ws.Cells(1, c).Value = "NOT OK"
GoTo NotOK
End If
Next r
ws.Cells(1, c).Value = "OK"
NotOK:
Set ce = ws.Cells(ws.Rows.Count, c+1)
Let lr = ce.End(xlUp).Row
Next c
End Sub
This should be faster and more efficient for large data sets. Especially if it is sorted smallest to largest.
Here you are:
=IF(MAX(A:A)<1)
If VBA is not required, here is a worksheet formula that should do the job, and will also ignore blanks and non-numeric entries:
This formula must be array-entered:
=IF(ISNUMBER(MATCH(TRUE,IF(ISNUMBER($A:$A),$A:$A)<1,0)),"NOT OK","OK")
If this formula must be located in A1, change the range references from $A:$A to $A$2:$A$1000 where 1000 represents the highest conceivable row number for the data.
To array-enter a formula, after entering
the formula into the cell or formula bar, hold down
< ctrl-shift > while hitting < enter >. If you did this
correctly, Excel will place braces {...} around the formula.
So, I'm trying to figure out how to write an Excel macro to populate Column C with either 3 or a 4 depending on the amount of numbers contained in Column B.
I have searched up and down for the right wording to this, but I keep coming up short.
Basically, I need the macro to look at the number of digits in Column B. If there are 12 digits then the number is a UPC, and if there are 13 then the number is an EAN. I then need the macro to populate Column C with a 3 for UPCs and a 4 for EANs. This needs to be for the entire range of rows in the spreadsheet.
Does anyone have any ideas? Thanks a lot in advance!
You don't need to use a dirty old loop, try this (much faster if you have lots of rows):
Sub HTH()
With Sheet1.Range("B1", Cells(Rows.Count, "B").End(xlUp)).Offset(, 1)
.Formula = "=IF(LEN(TRIM(B1))=12,3,IF(LEN(TRIM(B1))=13,4,""""))"
.Value = .Value
End With
End Sub
Or use a user defined function, which has the advantage of changing when the data in column B is updated.
Better yet just use a formula, you don't really need VBA.
Alternative VBA Method (looping the fast way):
Sub HTH()
Dim vArray As Variant
Dim lCnt As Long
With Range("B1", Cells(Rows.Count, "B").End(xlUp))
vArray = .Value
For lCnt = 1 To UBound(vArray, 1)
Select Case Len(Trim(vArray(lCnt, 1)))
Case 12: vArray(lCnt, 1) = 3
Case 13: vArray(lCnt, 1) = 4
Case Else:
End Select
Next lCnt
.Offset(, 1).Value = vArray
End With
End Sub
You can get the length of a cell's value by using Len() like this Len(Range("A1")) for example.
Now you just need to loop through your column and look at each value. If you look for the last used cell and loop only through that range your loop will be faster.
Here is how I would do it:
sub TestUPC()
With ActiveSheet
LastRow = .Cells(.Rows.Count, "B").End(xlUp).Row
End With
Dim rRng As Range
Set rRng = Range("B1:B" & LastRow)
For Each cell In rRng.Cells
If Len(Trim(cell))=12 then
cell.Offset(0, 1).Value = 3
ElseIf Len(Trim(cell))=13 then
cell.Offset(0, 1).Value = 4
End If
Next
End Sub
An in cell equation could look like this:
=IF(LEN(B1)=12,3,IF(LEN(B1)=13,4," "))
As suggested in the comments you might want to test for spaces depending on your data:
=IF(LEN(TRIM(A1))=12,3,IF(LEN(TRIM(A1))=13,4," "))
