Find and replace
Replace every occurrence of a word or pattern across your text at once.
How to use
- Paste your text, then type what to find and what to replace it with.
- Pick Exact, Ignore case, or Regex (supports $1–$9 backreferences).
- Copy the result — every occurrence is replaced at once.
Frequently asked questions
Do I need to escape dots and brackets?
Not in Exact or Ignore case modes — those treat your search literally. Only Regex mode interprets pattern syntax.
What are $1, $2 in the replacement?
Backreferences to capture groups in your regex. Searching (\d+)-(\d+) and replacing with $2-$1 swaps the two numbers.
Is there an undo?
Your original text stays in the input pane untouched — the replacement only appears in the result pane, so nothing is lost.
About this tool
Find-and-replace is the workhorse of text editing, and doing it in the browser means you can clean data without opening an editor: fix a recurring typo across a document, swap product names in a price list, normalise date separators, or strip a repeated prefix from hundreds of lines. Three modes cover the spectrum: exact match, case-insensitive match, and full regular expressions with $1–$9 backreferences — so a pattern like (\d+)-(\d+)-(\d+) replaced with $3/$2/$1 reorders every date in one pass. In the plain modes, special characters are treated literally, so searching for "1+1" finds exactly that.
