I want to use Notepad++'s Find/Replace feature to do the following:

Find: Semicolon featured by two digits followed by quotation marks (Example: ;25")

Replace: Replace the semicolon with a colon (Example result: ,25")

What I have so far: I can find what I want (see above) with the following regex: ;[0-9]{2}". However, I am not sure how to properly use the replace function. I know that I can refer with \1 to the matched group, but this does not solve the task.

Use a capturing group:

Find what:      ;(\d{2}")
Replace with: ,\1

The \1 is a numeric backreference that holds the value captured by Group 1, and the group is defined with a pair of unescaped parentheses in the pattern.

    @beta Yes, if you set the regex flavor to Perl/PCRE. In the replacement, you may change `\1` to `$1`. – Wiktor Stribiżew Apr 30 '19 at 15:40
