I'm currently using the EXACT function to compare two groups of text.

Is there a macro I can write or function I can use where Excel can tell me,
no it's not an exact match and highlight or format where the text starts to
not match.

So it matches up until it gets to the 255th character, and maybe bolds in
red at the start of non-exact-match.

Please note I'm using Exact b/c the spacing, text, everything within the
cell must exactly match.
