Find and replace with regular expressions
A focused regex replace tool: enter a pattern, a replacement string, pick
your flags, and watch the substituted output update live. Capture-group
references ($1, $2, $&) let you reorder and reshape matched text — for
example turning 2026-05-28 into 28/05/2026.
Patterns use the standard JavaScript regular-expression engine, so what works here works in your code. Nothing is uploaded; all matching happens in your browser.
