Hi SioSio,
Do you mean putting numbers into words, like 1234 returns One Thousand Two hundred Thirty-Four?

If so, then this monster formula I found online (apologies to the originator - I've lost your name) works well. No VBA.
Paste it into Cell C3. It converts the digits you've entered in Cell B3 into words

Regards - Dave.

Hi Fred.
This can be done with a few lines of VBA, which need only be run once for each range you wanted to make static.
Code that works through a predetermined range, cell by cell
Code that removes conditional formatting from the cell
Code that applies formatting in a 1-off way using the rules you set up in the original conditional formats
Next cell in range.
Are you familiar enough with VBA to do this?...
