About Find and Replace
Find and replace swaps a word or phrase in your text for another everywhere it appears. Paste your text, type what to find and what to put instead, and the Result shows the change with the number of replacements. It is free, needs no sign-up and runs in your browser, so nothing you enter is uploaded.
It matches the text exactly as you type it, so a dot or a bracket in Find means itself, with no escaping needed. Matching ignores capitals unless you tick Case sensitive, and it matches parts of longer words unless you tick Whole word.
Untick Replace all if you want only the first match to change. When you are happy, copy the Result, download it, or press Move to input to keep working on it.
How to use Find and Replace
- Paste your text into the Text box.
- Type the text to look for in Find and its replacement in Replace with. The Result below shows the new text and says how many replacements were made.
- Tick Case sensitive, Whole word, or Regex as needed. Untick Replace all to change only the first match.
- Press Add rule to run several replacements in order. Each rule works on the output of the one before it.
- Tick Remove line breaks, Remove extra spaces or Remove duplicate lines for a cleanup. Then Copy, Download .txt, or Move to input to work on the result.
Features
- Plain text or regular expression (JavaScript syntax) rules.
- Case sensitive and Whole word options, and Replace all or first match only.
- Regex options for multiline (^ and $ match at each line) and dot matches newline.
- Capture groups in the replacement: $1, $2, $&, $$ and named $<name>.
- Several rules in one pass, applied in order, with a replacement count for each.
- Cleanups for line breaks, extra spaces and duplicate lines.
- A clear message when a regular expression is invalid, instead of a crash.
- Move to input, Undo, Copy and Download .txt.
Worked examples
Find "colour", replace "color", in: Colour, colour, COLOURFUL gives color, color, colorFUL (3 replaced)
Tick Whole word to leave "COLOURFUL" alone, which gives 2 replaced on "Colour, colour, colourful".
The same rule with Replace all off, in: Colour, colour, colourful gives color, colour, colourful (1 replaced)
Privacy: how it works
- The replacing runs in your browser tab. Your text is not sent to Ulkaa or to any other server.
- This tool does not save your text. Close or reload the page and it is gone.
Tips
- Turn on Whole word when you replace short words, or "cat" will also change "category".
- Test a regex on a small piece of text before you run it on a long one. The count tells you whether it matched what you expected.
- Use Move to input to continue from the result, and Undo if a step went wrong.
- Keep a copy of the original text. This tool does not save it for you.
