How to replace text with regex

1Enter your pattern and any flags.

2Type the replacement, using $1, $2 or $<name> for groups.

3Paste your text and click Replace to see the result.

How do I reference capture groups?

Use $1, $2 and so on for numbered groups, or $<name> for named groups. Use $& for the whole match and $$ for a literal dollar sign.

Does it change my original text?

No. Your input stays as-is; the replaced result is shown separately so you can copy it.
