Macro merges csv files, how to make it merge xls files?

[abberyfarm]

Hello,

I have a macro that merges all csv files in folder into one file. How can I change it to merge all excel files in a folder into one file. Do you just replace csv with xls everywhere?

No, you can only do it for text files, because Excel files have a proprietary format and appending won't work. You would need to use this code:
