A couple of comments about the script:
- It works on single line text, multiline text and rich text field. I’ve coded it so that it stops if the field you select is of another type. It is possible that it will work on other field types, e.g. Email, URL (I’m pretty sure it will), but haven’t tested it out on those.
- I can’t figure out a way to replace something with nothing, i.e. remove a string from the field. This is because the “replace with” field won’t accept an empty string or at least you can’t click on “next” until you enter something. Maybe someone has a trick to get around this.
- The regex is case sensitive, i.e. “Dog” will not find “dog”
