I had this question after viewing how to update this VBA so that it checks the new data columns against old data columns?.


Bill was so kind to help me with the modification code below.

i was wondering if it is easy to modify the code, so that message box mentions what has changed? whether column order moved, or new column added or columnheader name changed.

thanks.
