[SOLVED] How do I use GREP to find and replace all hyphens between numbers in an InDesign document?

Issue

I am working on a multi-language book, and I need to find and replace all hyphens with en-dashes that occur between numbers in the citations section. I need to avoid all hyphens that exist between roman letters.

If I use a GREP [0-9]-[0-9] it selects the numbers before and after the hyphen and I have to manually select the hyphen and replace it with an en-dash. This is labor intensive.

Is there a way for me to find the hyphen that exists between the numbers, but EXCLUDE the numbers themselves from being highlighted? This way I can run a the Find and Replace to change what will probably be 1000+ manual changes?

I tried using GREP [0-9]-[0-9] to find the hyphens, but then couldn't find a way to have the find and replace keep the existing numbers.

Solution

That's what lookaheads and lookbehinds are for`

(?<=[0-9])-(?=[0-9])
