Find & Replace (batch) — multiline literal or regex
Paste a block, enter multiline find and replace strings, then switch between escaped literal matching and full JavaScript RegExp with g/i/m/s/u toggles. Literal mode uses a function replacer so “$” in the replacement is literal; regex mode uses normal $1 / $& substitution. Match counts update live — all local.
Frequently asked questions
No. Find/replace runs only on your device in this tab. Nothing is sent to LocalTools servers for processing.
Literal mode uses a function replacer so characters like “$” are copied as-is. Regex mode uses JavaScript replacement rules, so `$1`, `$&`, and `$$` have special meanings.
