About this tool
The Regex Matches Extractor is the list mode of a regex tester: write an expression, decide how each match should be printed with a template ($1, ${name}, \n, \t), choose the flags and get a clean, optionally deduplicated and sorted list. It turns delimited exports, log lines or scraped HTML into exactly the column you need, in your browser.
Ready-made extractors exist for IPs, e-mails, URLs and hashes.

Frequently asked questions
How does the output template work?
Each match is written through the template: $0 is the whole match, $1, $2 … are capture groups, ${name} a named group, \n a line break and \t a tab. With \n in the template every line becomes one entry that is then deduplicated and sorted.
Which regex flavour?
JavaScript (ECMAScript) with Unicode mode: lookbehind, named groups and \p{…} classes work in modern browsers. The (x) option strips unescaped whitespace and # comments from the pattern.
Can I output more than one group per match?
Yes: combine them in the template, for example $2 $1 or $1,$3, and add a line break with \n so each match becomes one entry.
