I was merging 3 large files CSV with roughly 4000 rows and 600 columns
I copied all three documents into one WorkBook - so I had 3 tabs and could just bounce between them.
After a full days work, I went to save and it would not save the work and all it said was it could only save 1 sheet.
I wasnt sure what was going and I do not know how to save my entire workbook.
Can you tell me how to do that please? I have lost all my work and need all these together
Any input?
