Find & Replace is a batch replace tool with regex support, processing happens locally in your browser with no upload.

Cleaning data and unifying terminology is far safer with batch replace. Regex mode handles patterns such as a number followed by a unit.

Paste or type your content into the input field at the top, or press the sample button to load demo data.
Adjust the options below the input, such as output format, separators, letter case or precision.
Press the main button to run the conversion. Results appear instantly in the output panel without a page reload.
When the result looks right, use the copy button in the corner, or download it as a local file.

Clean up stray spaces and line breaks before pasting for more accurate results.

How do I reference groups in regex mode?+

Use $1, $2 for capture groups, for example replacing (\d+) with $1 to reformat numbers.

Does it modify the original text?+

No. The input stays untouched; the result appears only in the output panel for you to copy.

Is Find & Replace free to use?+

Yes. The tool is completely free with no usage limits, and you never need an account or a sign-in.

Is the text I enter uploaded anywhere?+

No. All processing runs locally in your browser, so the input never reaches a server and is never logged or stored.

Does Find & Replace work on a phone or tablet?+

Yes. The layout is mobile-first, so inputs and buttons stay comfortable on phones and tablets in both orientations.

Can I copy the result into my own document?+

Yes. A copy button in the output panel puts the result on your clipboard, and you can also download it as a text file.
