This code works great but it's not enough - I'm hoping this code can be modified to accommodate a larger range of content (A:W) doing the following:
Sheet4 is considered the "Original"
Sheet5 is the sheet that someone has made changes to
Sheet 6 is where the list of all found changes are posted (along with the cell refc of where the changed cell was found in Sheet5)
Compare Sheet 4's Column A (A2) to Sheet 5's Column A (A2)
Compare Sheet 4's Column B (B2) to Sheet 5's Column B (B2), etc. out through Column W (the format of both sheets will be identical)
It's one directional (no changes will ever be made to the "Original" Sheet4)
It's possible new rows will be added at the base of the evolving Sheet5 but no inserting of rows - so existing content should align nicely for comparisons.
Hopefully, the attached small sample file will help everyone see what the current code does:
(it is tied to Sheet1 being the Orig, Sheet2 being the changing sheet, Sheet3 is what the code found).
The new example of what I'm hoping someone knows how to achieve is found on Sheets 4, 5, & 6 (done manually)
My real file has approx. 20 columns of a lot of categorical data so listing everything going downward on Sheet 6 was much easier to read..
Having a cell refc listed makes it much easier to scan the findings and determine whether or not it's okay to retain the change made (and where to locate it quickly if not)
