Excel Geeking: Extracting Comments Using VBA

A couple of months ago a colleague moved into a new position at work and inherited a big ugly spreadsheet. Happens to the best of us, amiright? The biggest challenge with this spreadsheet is that the previous owner, who has since retired (and good for him!) didn’t update his status notes and comments in a cell or a column. He kept them all in in-cell comments.

In. Comments.

Needless to say, the spreadsheet my colleague inherited had a couple of billion comments, some of which were absolutely enormous. She wanted to know if there was a quick way to extract all of the text out of the comments, and put them in the first available cell to the right. And if the old comments could be deleted as part of the extraction, that would be a bonus.

To which I said, of course that can be done!

And so, I wrote this little routine as a way of pulling the text from comments, placing it in the first available cell to the right, and blowing away the old comments if desired. Enjoy!

Sub ExtractComments()
'*******************************************************************************
' Description:  This iterates through all of the used cells in a worksheet
'               and where comments exist, extracts them and places them
'               in the next free cell to the right in the row where the
'               comment exists.

  1. Scott, I like your option to remove the comments from the cells — that’s a great way to clean up a sheet! You could loop through the rcomments range, instead of the used range, to make it a bit faster.

    1. Yeah, using the Comments range from SpecialCells probably would have been a better way to go. I always forget about SpecialCells when I’m doing range work.
