Frequently asked questions

Can I use regular expressions?

Yes - enable "Treat find as regex" to use full JavaScript regular expression syntax in the find field.

Does it replace all matches or just the first?

All matches are replaced by default.

What happens with an invalid regex?

The tool shows a clear error message explaining the pattern is invalid, rather than crashing.
