in reply to Re: Merging 2 xlsx files (UPDATED)in thread Merging 2 xlsx files
If you are trying to learn programming you really are not showing any effort. As the fellow Monks already said this is a not a free code forum. Show us some effort, show us your code and then you can ask for advice / code improvements etc.
I will answer your question because I found it extremely easy. Did you read the documentation of the Excel::Writer::XLSX/write_comment( $row, $column, $string, ... ). Regarding reading the comments from you spread sheet, this is for you to figure it out. Show us the effort and we will try to help.
Hope this helps, BR.
