I have quite a few cells that contain formula, then with VBA the outcome of this formula is the value for a variable, like so:
On sheet in cell AS4:
=SUMPRODUCT(MAX((ROW($AE$4:$AE$997))*($AE$4:$AE$997<>"")))
and then in my VBA:
numRows = ws.Range("AS4").Value
However this is starting to get hard to keep track of which cell is feeding which variable, avoiding overwriting those cells on the sheet by accident, etc.
I need to be able to perform this calculation within VBA if I can, removing the need to have "calculation cells" on my sheet.
I have discovered there is a way to use formula with WorksheetFunction, but only found simple examples of this and cannot adapt it to my situation above.
numRows = WorksheetFunction.SumProduct(MAX((ROW($AE$4:$AE$997))*($AE$4:$AE$997<>"")))
Is not going to work...
Is there a way to do this, or am I better scrapping the idea of using formula and using a pure VBA method?
With help from SJR this was the answer:
numRows = [=SUMPRODUCT(MAX((ROW(Weights!$AE$4:$AE$997))*(Weights!$AE$4:$AE$997<>"""")))]
A bit more research taught me that evaluate(" ") can be just replaced with square brackets [ and ]. Although, if I had variables in the mix of this formula or the formula wasn't constant then I would have to use Evaluate.
I also needed to add the sheet name to the formula as this formula was no longer functioning within the sheet and AE4:AE997 was no longer referring to the correct sheet.
Doubling up on quotes is also necessary as it is code and sees " differently to a formula on the sheet

I have a formula that I don't want in my workbook until other specific functions are performed. So I'd like to have some VBA code that populates a column when I determine best. Here is the formula:
=VLOOKUP(A2,INDIRECT("'"& Day(C2)&"'!$A$127:$C$153"),3,TRUE)
The single ticks, and &s and !, always get hung up in the VBA code.
Is there some way to encapsulate a formula so it can be used in a range, or is that not available?
Do I need to encapsulate the various pieces?
You just need to double up any quotation marks:
Range("G2:G1000").Formula = "=VLOOKUP(A2,INDIRECT(""'""& Day(C2)&""'!$A$127:$C$153""),3,TRUE)"
for example.
I have this formula that looks at various criteria across multiple columns and checks to see that if all the all the criteria match, it will paste data from one column to another. I've tried a couple ways to get it into VBA, but I can't seem to get anything to work. Thanks!
=INDEX($D$2:$D$1112,MATCH(1,($A$2:$A$1112=$U$7)*($C$2:$C$1112=$W$7)*($B$2:$B$1112=F3),0))
You are not going to be able to use that array formula to directly return a value to a cell. VBA does not process an array formula the way that the worksheet can. The best method is to use the worksheet's processing or one of the Application Evaluate methods.
Your lack of a worksheet to reference troubles me. When a formula is in a worksheet cell, it knows what worksheet it is on. When using formulas within VBA, the parent worksheet is a 'best guess' without explicit worksheet referencing.
Here are three methods to put the results from that array formula into Z2:Z4 on the active worksheet. Remember that these cell references should be modified to include the worksheet name.
With ActiveSheet
'this simply puts the formula into the worksheet then reverts the cell from the formula to the returned formula value
.Range("Z2").FormulaArray = "=INDEX($D$2:$D$1112, MATCH(1, ($A$2:$A$1112=$U$7)*($C$2:$C$1112=$W$7)*($B$2:$B$1112=F3), 0))"
.Range("Z2") = .Range("Z2").Value
'this uses the 'square bracket' method of evaluating a formula on-the-fly
'the formula being evaluated can be array or non-array
'this method is does not like building a formula string from pieces of text
.Range("Z3") = [INDEX($D$2:$D$1112, MATCH(1, ($A$2:$A$1112=$U$7)*($C$2:$C$1112=$W$7)*($B$2:$B$1112=F3), 0))]
'similar to the method directly above, Application.Evaluate does just that.
'the formula being evaluated can be array or non-array
'this method is easier to build a formula string from pieces of text
.Range("Z4") = Application.Evaluate("INDEX($D$2:$D$1112, MATCH(1, ($A$2:$A$1112=$U$7)*($C$2:$C$1112=$W$7)*($B$2:$B$1112=F3), 0))")
End With
You need 2 changes:
(1) To use a function in VBA when it is available in native Excel, you need to preface each function with Application.WorksheetFunction. ie:
x = Application.WorksheetFunction.Sum(y,z)
(2) To reference a cell within a sheet, in VBA, you need to access it specifically, in one of a few ways. The simplest for our purposes is the RANGE property, as follows:
x = Application.WorksheetFunction.Sum(Range("A1:A2"))
So to put those two changes together, your formula would look like this:
=Application.WorksheetFunction.INDEX(Range("$D$2:$D$1112",Application.WorksheetFunction.MATCH(1,(RANGE("$A$2:$A$1112"=RANGE("$U$7")*(Range("$C$2:$C$1112"=Range("$W$7")*(Range("$B$2:$B$1112"=Range("F3"),0))
Although I see now having gone through this that you seem to be using an Array Formula - not sure if any special jigging is required to get that to work.
I've been using a conditional format formula =OR(B2=B1,B2=B3) to highlight consecutive duplicates. I then use format painter to copy the formula to all columns in my excel table.
I have set up a button that will, amongst other things, copy a workbook into a new workbook. I now want to include the above formula in this macro. My final objective is to replace all of the cells found with this formula with an asterisk (*).
I first tried to just pop the formula into the macro as a starting point -
For Each sh In Destwb.Worksheets
With sh.UsedRange.FormatConditions _
.Add(Type:=xlExpression, Formula1:="=OR(B2=B1,B2=B3)")
.Interior.Color = RGB(198, 239, 206)
End With
Next sh
But this just makes a mess of seemingly randomly highlighted cells. I'm not sure where I've gone wrong. Even column B highlights are all wrong. Could the header in B1 affect this? It doesn't when I use the CF normally. How can I expand the CF into all columns uniquely?
Finally, how do I go about working a replacement of formatted cells into this formula? Or is there a quicker/easier way to meet this end-goal?
I didn't realise I could add custom text in that way. That's moved me a good couple of steps forward.
Taking Balinti's suggestion into consideration I've tried a workaround. I was making a couple of assumptions that turned out to be wrong. I have been able to enter the CF into the Array of data that I have in my original workbook. It's not as simple as putting it into a table, but by manually selecting the range in each column and inputting the CF I have made it work.
I also wasn't sure if the formatting would carry through to the new worksheet as I have used the Paste Special command to convert the array formula to values in the new sheet. It does, however, carry the formatting across which is very handy.
It's not the perfect solution for me but it appears to be working so far. I still need to test what happens when I change the date and get updated data. It would still be interesting to know if I can move this formatting into my macro though. Any tips?
I'm trying to put this =IF(D49>0,D49-D50-D51+D52+D53,) into a cell D54 by using macro.
My code is as follow
Range("D54").FormulaR1C1 = "=IF(D52>0,D49-D50-D51+D52+D53,)"
But when I run the macro.
Cell D54 gets this =IF('D52'>0,'D49'-'D50'-'D51'+'D52'+'D53',) instead.
Excel adds quotation marks to each dells in the formula, render the formula useless. How can I get macro to into formula as formula?
I think you are having issues because you are using the R1C1 formula property for your range, yet you are using classical cell references in your formula. You should be using the Range("D54").Formula property. So your code would look like:
Range("D54").Formula = "=IF(D52>0,D49-D50-D51+D52+D53,)"
You could just use Range("D54").Value = "=IF(D52>0,D49-D50-D51+D52+D53,)"
I have used that method before and hand good results with it.
I've come up with a useful trick, where I create a named range that refers to the current worksheet, by using the following formula:
=RIGHT(CELL("filename",INDIRECT("A1")), LEN(CELL("filename",INDIRECT("A1"))) - FIND("]",CELL("filename",INDIRECT("A1"))))&T(NOW())
Where the INDIRECTs are there ONLY to stop Excel from Converting A1 --> Sheet1!A1. This works beautifully until I need to call evaluate on it from VBA (which does happen).
Can anyone tell me how either (1) to evaluate a name with this formula in VBA or (2) to get a sheet non-specific reference into the formula. I'd rather not use VBA, since it'll get evaluated ~12000 times, and that's likely to be slow, but if need be, it's probably ok. However, please bear in mind that the sheet it is calculated from is quite unlikely to be ActiveSheet, so the context for the Range() function in VBA is a little tricky - hence why I'm asking in the first place.
One possible approach: use a simple UDF which just returns the name of the sheet it's called from.
Eg:
Function SheetName()
SheetName = Application.Caller.Parent.Name
End Function
