> Find And Replace Blanks (vba), Any Version

I'm running some VBA code from an MS Access application that has to fix up values in an Excel worksheet.

It needs to go through a huge worksheet (500,000 rows) and find all blank values in Column D and replace them with the values from column A (in the same row as the blank)

I wrote some code that walks down the rows and does this, but it's glacially slow.

Then I tried this, but it just replaces the blanks with the header from row 1 of column A:

.Columns("AG").Replace What:="", Replacement:=.Columns("AD"), LookAt:=xlWhole, SearchOrder:=xlByRows, MatchCase:=False, SearchFormat:=False, ReplaceFormat:=False

Any suggestions?

If you only want to replace Column D with values from Column A, why reference multi-column range? I tried your code and I get "type mismatch" error on the Replacement argument. If I use a literal value like "X", no error but no edits either. I change "AG" to "D" and it does replace empty cells with "X"

So I am not sure this method can do the dynamic reference you want.
