Hello Keith. This was my business back in the 90s for multiple documents from multiple sources.
All "document cleansing" is based on locating specific items and substituting items with (usually) different characteristics, all the way from text, fonts, sequence numbering and WP5.1 document tables (built with those weird graphic characters) with MSWord tables.


I found it expedient to write a single find-and-replace macro and then feed it the input and output characteristics from a table of rules which drove the whole process. I use the same procedure to this day.


If you anticipate repeated use of find-and-replace code to change numerous items and/or characteristics, please let me know and I will make my code available to you.
Cheers, Chris
