User Defined Functions NOT recalculating

Question

I recently took a large, stable XLSM file, and split it apart into an XLAM and XLSX. Thousands of cells in the XLSX call (udfs) functions in the XLAM, and each such udf beg

Answer 1

Press CTRL+ALT+SHIFT+F9

This may recalc more than wanted, but it updated my UDF.

Answer 2

Excel will monitor the range mentioned in the formula for any change, I faced this today and I was thinking and realized that. So to fix it, make a dummy argument in your function which takes the range you want to monitor or create a dummy function. In my case I called it monitorRange which returns nothing

Function monitorRange(rng As Range)
End Function

and I mentioned it in my formula example

=myfunction(a,b) & monitorRange(RANGE_TO_MONITOR)

This worked very well and it should work with any other function

Answer 3

I was having the same issue...I found (in another post) that adding Application.Volatile to the function code made it calculate with the spreadsheet (f9)

Answer 4

My screen shot:

I had the same problem. Find and Replace works, but not very nice. My solution is:

go to Data tab > Edit links > Click Open Source will resolve this

Answer 5

You can force recalculation in this situation by search and replace on the = which is at the start of all formulae. You can also make this into a macro and map it to a key combination.

Edited to add

See the macro Greg Glynn has in his answer.

Answer 6

For UDFs who can access to Application instance could use:

Application.CalculateFull()
