What is this advanced find and replace tool?

This is a free, browser-based find and replace tool with full regular-expression support, case-insensitive matching, multiline and dot-all flags, capture-group back-references and a live match count — and zero data leaves your device, because every operation runs in JavaScript on your own machine.

How do I find and replace text with regex online without uploading it?

Paste your text, type what to find and what to replace with. Toggle regex, case-insensitive, multiline and dot-all as needed; the replaced text and match count update live. Nothing is uploaded — it all runs in your browser.

Key features

Full regex flags
Toggle case-insensitive (i), multiline ^/$ (m) and dot-all (s) flags, with global replace always on for find-and-replace.
Capture groups
Use $1, $2 back-references in the replacement to reorder, format or reuse parts of the match — perfect for restructuring lists or markup.
Live match count
See how many matches will be replaced before you commit, updated on every keystroke.
Plain or regex modes
Switch between literal find-replace and a full regex engine, so simple swaps stay simple while complex transforms stay possible.

How to use it

Paste your text, type the find pattern and replacement. Toggle regex on for patterns or off for literal find. Optional flags (case-insensitive, multiline, dot-all) refine matching. The output and match count update instantly. Copy or download the result. Nothing is sent to a server.

Frequently asked questions

Does it support capture groups?

Yes. Use $1, $2 and so on in the replacement to reference groups captured by ( ) in the pattern — handy for reordering name parts, swapping date formats or restructuring CSV rows.

What do the multiline and dot-all flags do?

Multiline makes ^ and $ match the start and end of each line instead of the whole string. Dot-all makes . also match newline characters, so a single pattern can span multiple lines.

Is my text uploaded?

No. Everything runs in your browser using the native RegExp engine, so even confidential drafts and production data stay private.

Built by the Toolbox team on the browser's native RegExp engine with standards-aligned flag handling and capture-group replacement, so output matches what your code, editor or sed pipeline would produce.
