I inherited a massive file with tons of sheets and formulas. Each sheet has over 30 conditional formats. Is there any way to remove a cluster of the conditional formats (but not all of them) at one time?
You mean you want to remove from contiguous cells, if so select the block of cell and from the ribbon in the editing section choose clear/formats. Even if you select some cells with no formatting in your selection it will still be alright. If they are non-contiguous then just Ctrl click on the cells then do as above.
If you know the exact ones, you can do it via macros, but it could be tricky to make sure you always get the right ones. Or, if the amount that you need is very few, perhaps you should just clear them all out, and then use a macro to rebuild? I'm not sure what would be best path for you situation.
