  1. Paste or type the text you want to process into the box on the left.
  2. Enter what you are looking for in the "Find" field.

  6. Click "Copy" to put the result on your clipboard.

Features

  • Two search modes: plain text and regular expression.
  • Optional case-sensitive matching for finer control.
  • Instant preview of the replaced result, exactly as it will come out.
  • One-click copy of the output so you can move on quickly.
  • Runs entirely in the browser, so your text is never uploaded to a server.

Use Cases

Renaming variables in bulk
Swap an old variable name for a new one throughout a block of code, using regex to match whole words precisely.
Stripping junk characters
Replace the regex \s+ with a single space to clean stray whitespace and line breaks out of an article in one pass.
Normalizing punctuation
Convert mixed full-width and half-width punctuation to a single consistent style across a document.
Redacting sensitive terms
Replace specific keywords with placeholders so a document can be shared safely once the sensitive parts are masked.

FAQ

Are regular expressions supported?
Yes. Tick the regular expression option and the find field accepts standard JavaScript regex syntax, for example \d+ to match digits.
Does leaving the replacement empty delete matches?
Yes. Leave the "Replace with" field blank and clicking replace removes every match from the text.
How much text can it handle?
The tool runs locally in your browser and comfortably handles hundreds of thousands of characters. Very large documents are best processed in sections.
Is my text sent to a server?
No. All processing happens locally in the browser and the content is never transmitted anywhere.
