  • 0

I have an Excel VBA sub that (among other things) pastes a lookup formula into some cells. The lookup formula is presently of the form

LOOKUP(RC5,lookup.xlsx!Item,lookup.xlsx!R2C:R559C)

but the size of the lookup table will change. Is there a good way to find the size of the lookup table, that is, the last row?

In a pinch I suppose I could open the lookup file (what’s the command for that?) and do

Windows("lookup.xlsx").Activate
last = Range("a65536").End(xlUp).Row    
Windows("whatever.xlsx").Activate

but I’m not sure if there’s a better way.

    Finding the last used cell has a bad reputation in Excel AFAIK. See for example this , although a bit outdated. If you can, just be sure to insert an EOF value in the last used row and scan for it.

    Edit

    Remember:

    • A null value (or spaces) may serve well as an EOF flag. Be sure to be consistent.
    • You may always include full columns in the lookup range and excel will take care of the end (if there are no more used cells under your range. Like in =LOOKUP(A1,C:C,D:D)
