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 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$997<>"""")))]
A bit more research taught me that evaluate(" ") can be just replaced with square brackets [ and ]. Although, if I had variables in the mix of this formula or the formula wasn't constant then I would have to use Evaluate.
I also needed to add the sheet name to the formula as this formula was no longer functioning within the sheet and AE4:AE997 was no longer referring to the correct sheet.
Doubling up on quotes is also necessary as it is code and sees " differently to a formula on the sheet
I'm trying to apply a formula through VBA for a particular range. This is the code in my VBA editor:
Sheets("WBR45").Range("AE105").Formula = "=PERCENTILE.INC(TP!$A$3:$A$30:$B$3:$B$30:$C$3:$C$30:$E$3:$E$30,50%)*24"
And the below formula gets updated in the destination cell when this is run:
=PERCENTILE.INC(TP!$A$3:$A$30:$B$3:$B$30:$C$3:$C$30:$E$3:$E$30,50%)*24
But I get an error in the destination cell as #VALUE!.
And when I click on "Show Calculation steps", only this part of the formula is underlined :
TP!$A$3:$A$30:$B$3:$B$30
I have no idea what is wrong with this simple formula. Can someone please take a look
Honestly I have no clue about what you're doing with this, but this may fix it:
"=PERCENTILE.INC(TP!$A$3:$A$30:TP!$B$3:$B$30:TP!$C$3:$C$30:TP!$E$3:$E$30,50%)*24"
You appear to have three errors in your formula:
You are using : to separate ranges instead of ,
You are not specifying which sheet the second, third and fourth ranges refer to, therefore it is defaulting to the sheet on which the formula occurs (i.e. sheet "WBR45")
Multiple ranges will need to be enclosed within brackets (...) in order to be passed as a single range.
If you are trying to have your function operate on the range A3:C30 together with the range E3:E30 (i.e. A3:E30 but ignoring column D), with those ranges being on the "TP" worksheet, I believe that you need to change your formula to
Sheets("WBR45").Range("AE105").Formula = "=PERCENTILE.INC((TP!$A$3:$A$30,TP!$B$3:$B$30,TP!$C$3:$C$30,TP!$E$3:$E$30),50%)*24"
or, slightly simplified
Sheets("WBR45").Range("AE105").Formula = "=PERCENTILE.INC((TP!$A$3:$C$30,TP!$E$3:$E$30),50%)*24"
I have this formula that looks at various criteria across multiple columns and checks to see that if all the all the criteria match, it will paste data from one column to another. I've tried a couple ways to get it into VBA, but I can't seem to get anything to work. Thanks!
=INDEX($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 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
I'm building a macro in Excelto run rules against a set of data and output whether each row passes or fails the rules. I want to be able to add, remove, or alter the rules without altering the macro. As such I have a DATA worksheet and a RULES worksheet and the macro generates the OUTPUT worksheet and then populates it.
RULES is set up so that each different rule is enumerated on a different row. For this to work I need to be able to enter the actual VBA code relevant to the rule in on RULES, then I need to have the macro look at that column on RULES and execute the code in the cell.
Simplified example of my setup-
DATA has : ID, Dividend1, Dividend2, Divisor. There are n rows on DATA.
An example of a row on DATA might be ID="123", Dividend1=5, Dividend2=7, Divisor=35.
RULES has : Name, Formula, Threshold. For simplicity's sake there is only .
Let's set the as Name="Example", Formula=[see below], Threshold="0.15" (Threshold is used for conditional formatting in the macro, in this example it is unused.)
I'm going to use pseudocode for Formula just to eliminate the need to explain some of the irrelevant particulars of my macro so far. RULES.Formula should contain a line of VBA code that carries out-
If CurrentDATARow.Dividend1 = Empty Then
CurrentDATARow.Dividend2 / CurrentDATARow.Divisor
Else
CurrentDATARow.Dividend1 / CurrentDATARow.Divisor
End If
So, all of this explanation just to give context to this question: What can I do in the VBA of the macro to make it read the contents of RULES.Formula and make it execute that code inline with the rest of the macro?
If you have (say)
IF({dividend1}="",{dividend2}/{divisor},{dividend1}/{divisor})
stored in a "rule" cell (note do not include the "="), you can use Replace() to replace the placeholders with the relevant cell addresses for each cell in the row you're checking.
Then use something like
Dim val
val=Sheet1.Evaluate(yourformulastring) 'evaluate vs. specific worksheet
If Not IsError(val) Then
'check against thresholds etc
End If
If the evaluation results in an error you can test with IsError(val) as shown, otherwise it will return the result of the formula, which you can test against your "threshold" value cell. If you set background colors on your threshold cells you can color each row according to which threshold was exceeded.
NOTE without a worksheet qualifier, Evaluate will calculate the formula based on the ActiveSheet, so make sure the right sheet is active when this runs if you don't use the qualifier.
you could store your Tests/Rules as Excel worksheet formulas in Named ranges. Then you just call them from the cells.
see Ozgrid: Named Formulas
If you give us some example data and the type of calculations or rules I can give you a couple of examples.
