I am fairly new here, so if this go against the rules please tell me.
I have an issue that seems pretty simple but I wanted to check to make sure. I have been trying to see if I could create a new row by combining every variable from one column with another, like so:
Column 1 Column 2 Combined
A 1 A1
B 2 A2
3 A3
B1
B2
B3
But instead of typing the combinations manually, I wanted the combined column make this combination without user input and to update automatically whenever column 1 or 2 has a row added or removed. I have been trying to figure out if there is some way to use the concatenate function in excel or the & sign but neither methods seems to work. I was thinking trying to code this in visual basics.
The main question: is this possible to do in excel? If so which function(s) could I use?
This assumes your data has one header row (row 1), Column 1 is column 'A' and Column 2 is Column 'B'. Place the formula below in an empty cell and copy down as far as your data permits.
=INDEX(A:A,INT((ROW(A2)+1)/(COUNTA(B:B)-1))+1)&INDEX(B:B,MOD(ROW(A2)-2,3)+1+1)
now if you want to add a little flag to let you know you have more row than you need for your data you could add the following:
=IF(ROW(A2)-1>(COUNTA(A:A)-1)*(COUNTA(B:B)-1),"Data Exceeded",INDEX(A:A,INT((ROW(A2)+1)/(COUNTA(B:B)-1))+1)&INDEX(B:B,MOD(ROW(A2)-2,3)+1+1))
According to: https://www.extendoffice.com/documents/excel/3097-excel-list-all-possible-combinations.html
You can use this formula:
=IF(ROW()-ROW(**$D$1**)+1>COUNTA(**$A$1:$A$4**)*COUNTA(**$B$1:$B$3**),"",INDEX(**$A$1:$A$4**,INT((ROW()-ROW(**$D$1**))/COUNTA(**$B$1:$B$3**)+1))&INDEX(**$B$1:$B$3**,MOD(ROW()-ROW($D$1),COUNTA(**$B$1:$B$3**))+1))
In the above formula, $A$1:$A$4, are the first column values, and
$B$1:$B$3 are the second list values which you want to list all their
possible combinations, the $D$1 is the cell that you put the formula,
you can change the cell references to your need.
In your case, you should use:
=IF(ROW()-ROW($C$2)+1>COUNTA($A$2:$A$3)*COUNTA($B$2:$B$4),"",INDEX($A$2:$A$3,INT((ROW()-ROW($C$2))/COUNTA($B$2:$B$4)+1))&INDEX($B$2:$B$4,MOD(ROW()-ROW($C$2),COUNTA($B$2:$B$4))+1))

I am trying to lookup values from Table 1 to Table 2 based on Col1 in Table 1.
The catch is that Table 1 has duplicate values (for example, A is repeated 3 times) but I don't want to duplicate the returned value from Table 2.
How can this be done through either excel or sql (e.g. LEFT JOIN)?
What SQL are you using? Are you familiar with CTE and partition?
Have a look here: https://social.msdn.microsoft.com/Forums/sqlserver/en-US/597b876e-eb00-4013-a613-97c377408668/rownumber-and-cte?forum=transactsql
and here: (answer and 2nd comment): Select the first instance of a record
You can use those ideas to create another field that tells you whether the row is the first, 2nd , 3rd etc occurrence of Col1. Eg you'd have something like
1 B Red 150
2 B Red 150
and you can then update col3 to be zero where this new field is not 1.
EDIT: since you asked about Excel: in Excel, sort by whatever criteria you may need (col 1 first, of course). Let's say that Col1 starts (excluding the heading) in cell C2. Set cell B2 =1. Then write this formula in cell B3:
=IF(C3=C2,B2+1,1)
and drag it all the way down. This will count the occurrences of col 1, ie it will tell you which is the first, 2nd etc time a given value appears in col1. You can then use it as as the basis to change the value in other columns.
Also, it is not good practice to have a column where the first cell has a different formula from the others. You can use the same formula nesting another IF and referencing the row, so as to set one formula for the first row and one for the others.
I have got an Excel spreadsheet. This spreadsheet has just one tab in it. The Tab name is dynamic in nature and changes every week also the number of rows.
I have column A filtered already with a VBA macro. A1 has the header.
Now, I wanna find how many rows are there in this already filtered column A.
I am looking for any VBA function.
I have tried using Subtotal function.
=Subtotal(103,A2:A1345)
But I don't know the end range. As of now the end range is A1345. It will change every time in future if the new rows are added.
I tried multiple things but those did not work. I am quite new to VBA.
If A1 will never be blank, you could use (in a column other than A)
=Subtotal(103,A:A)-1.
Or, if there will be data below your table not to be counted, then format your table as a Table and use structured references (and this formula could go into column A)
=SUBTOTAL(103,Table1[column_header])
You can put the formula in column A if you use another column's last populated cell as the demarcation point.
If column B contains numbers then,
=subtotal(103, a2:index(a:a, match(1e99, b:b)))
If column B contains text then,
=subtotal(103, a2:index(a:a, match("zzz", b:b)))
Im new in VBA and want to know how can i format my table in such a way that each name in Column one do only have 1 row in between.
Some of them do have more than 1 row in between and some of them doesn't have. I just need to format then in such a way where every name on column A has 1 blank row in between. Any help would be appreciated!
Please note that i have thousands of data so manual will not work.
also i tried doing the filtering and convert them into single block. the problem with single block is that my column c do have more than 1 information which is connected to column a, .
here is an example.enter image description here
I have two worksheets: the first one is main (Table 1) and the second is the report (Table 2) generated from values in two columns in the main table. When the conditional formatting is triggered the cell in Table 2 is highlighted:
In Table 1, the primary key is a compound key combining id-year columns.
In Table 2, the report checks whether the related column-row exists in Table 1 and if so the cell is to be highlighted.
How I can achieve it using conditional formatting?
I've some steps that will converted to conditional formatting in cell below:
In selected cell, the paired value year-id from table 2 will be
looked up in Table 1 in the relevant column pairing.
If the related paired-value exists, the cell in Table 2 is highlighted (the color differs between ids) and if not it won't be highlighted.
For Step 1. I can't find the right formula. If there is another solution I'll considered it.
Can Step 2. be achieved with VBA and if so, how?
[updated]
Based on pnuts's suggestion, the problems above I can achieve with some modification to get vary color but recently I get different format value that appear in table 1 that look like "2003-2004". In second table, the related column (2003 & 2004) must be highlighted.
How I can check "-" sign then highlight two related columns?
Assuming Table1 and Table2 are both in Cell B2, one way is to put =Sheet1!C5&Sheet1!D5 in your Table2 sheet in A5 and copy down until a cell appears blank, then apply CF to =$C$6:$M$11 with this rule:
=MATCH($B6&C$5,$A:$A,0)>0
This would only apply one colour throughout (which may be less confusing than 5 or more) but I take it you know how to break this down into separate rules for different colours by restricting the range for each to one row at a time.
Given
O 1 2 3 A
A 4 5 6 B
B 7 8 9 D
O 3
C 15
T 18
I'm looking for VBA code to validate that when column A contains a value that the remaining columns also contain values and when it doesn't contain a value, that columns 2 & 5 also contain values but 3 & 4 don't.
I've simplified the example, in a real sheet there will be many more columns and rows to check.
I've considered COUNTIF and INDEX/MATCH and array forumlas but from my understanding these all work on single columns at a time.
I want to do something like WHEN A1:An<>"" THEN COUNTBLANK(B:E) ELSE COUNTA (C:D)
Is the best way to use autofilter using blanks in A and then countblank and then a second autofilter for values in A.
Thanks
You can do it with a couple of nested IF formulae as follows:
=IF(A1<>"",
"A not empty, "&IF(COUNTBLANK(B1:E1)=0,
"B:E not blank",
"B:E have blanks"),
"A blank, "&IF(AND(COUNTBLANK(B1)+COUNTBLANK(E1)=0,
COUNTBLANK(C1)+COUNTBLANK(D1)=2),
"Columns 2&5 have values and Columns 3&4 don't",
"but condition not met"))
The reason for going down the VBA route is that I want a generic reusable function as opposed to a formula I copy between cells and sheets changing the columns etc along the way ending up with a lot of duplicate code.
So something that takes a column to test and a value to test it with. Third parameter would be a range of columns to validate, and the fourth parameter the validation.
I don't want any solution to have the columns hard coded and I don't want intermediate totals at the end of rows. This is fairly easily achieved in Excel itself...
The reason for trying to use countblank is that I can apply it to a range.
After a lot of searching I discovered this (the columns don't match the original example)
=SUMPRODUCT((A2:A19<>"")*(B2:D19=""))
=SUMPRODUCT((A2:A19="")*(D2:D19=""))
=SUMPRODUCT((A2:A19="")*(B2:C19<>""))
Nice huh? I just need to convert it into VBA now.
Thanks
