(I'm new, please let me know if I violate the community rules.) This follows up on threads from 2019 (January 10) and 2005 (august 12). I used this command -- =CELL("protect",INDIRECT(ADDRESS(ROW(),COLUMN())))=(#REF!) -- in conditional formatting to make numbers red and this command -- CELL VALUE - "REPORT" -- to put a dark background in cells where I manually entered the text, "REPORT." This got out of hand and now I have 100,000 conditional formats spread among 150 tabs in a 25 mb workbook many of which now show #REF because I subsequently moved columns and row. I want to delete these two (but not other) conditional formats. I no longer need the red font for negative numbers or the dark background for "REPORT". As I read these and other posts, it seems like a VBA function can do it nicely, but I know enough about Excel to be dangerous and nothing at all about VBA. If someone his inclined to help it would be very much appreciated. [Thanks, great site!]
