What do match case and whole word do?

Match case only finds text with the same capital letters, so Sale doesn't match sale. Whole word only finds the text when it isn't part of a longer word, so cat matches cat but not catalog or concat. Both can be combined, and both work with regex too.

How do I use regular expressions?

Tick Regex and type a JavaScript regular expression in the Find box, without slashes. For example \d+ finds numbers, ^[ \t]+ finds spaces at the start of each line and https?://\S+ finds links. In the Replace box, $1, $2 insert capture groups, $ inserts a named group, $& inserts the whole match and \n inserts a line break. If the pattern isn't valid, the tool explains what's wrong instead of failing.

Can I run several replacements at once?

Yes. Add a rule for each replacement. Rules run from top to bottom, and each one works on the result of the previous one, so you can build up a clean-up routine, such as fixing names, then dates, then spacing, and run it with one click.

How does replacing one by one work?

Click a rule to make it active. Its matches are highlighted in the Matches view, and the current one is marked. Use Previous and Next to move between them, and Replace this to change only the current match. Replace all runs every rule on the whole text.

Can I undo a replacement?

Yes. Every Replace this and Replace all can be undone, up to the last 20 steps. The result preview always shows what Replace all would produce before you apply it.

Is there a size limit?

Text of several megabytes works. Up to 200,000 matches are counted per rule, and the highlighted view shows a window of matches around the current one so the page stays fast. Replace all always changes every match.

Match 1 of 2

Hi {name}, thanks for commenting on our post! Here is your discount code: SPRING10. The code SPRING10 works until 31/05/2026. Reply to this message with any questions, {name}.

Bulk edits without a text editor

Find and replace is the quickest way to update a template, fix a repeated typo or rename a product across a long document. This tool works on any text you paste, on any device, without installing an editor, and shows every match before you change anything.

Useful patterns

Fill in a template: find {name} and replace it with a name, then add rules for other placeholders.
Swap a discount code or link in every saved reply when an offer changes.
Reformat dates with regex: find (\d{2})/(\d{2})/(\d{4}) and replace with $3-$2-$1 to turn 31/05/2026 into 2026-05-31.
Remove things: leave Replace empty to delete every match, for example [ \t]+$ with Regex on to strip spaces at the end of every line.

Regex notes

Patterns use JavaScript syntax with the Unicode flag, so \p{L} matches any letter in any language. ^ and $ match at the start and end of each line, and \n matches a line break, so you can join or split lines. Patterns that match nothing (such as x* between letters) are skipped.
