How to use
01
Paste your source text
Drop the text into the Input box on the left. Anything works, from a single paragraph to a CSV export copied straight out of a spreadsheet.
02
Fill Find and Replace with
Type the search term in the Find field and its substitute in the Replace with field. The live match counter shows how many hits exist before you trust the output.
03
Toggle options and copy
Check Regex for patterns, Case-insensitive to catch every casing, or Multiline so anchors work per line. When the Result pane looks right, use the copy button beside it.
Why Find and Replace
- Plain or regex find-and-replace with live preview.
- Case-insensitive and multiline flags supported.
- Live match count.
Common questions
Does the find and replace tool support regular expressions?
Yes. Tick the Regex checkbox and the Find field is treated as a JavaScript regular expression with the global flag applied. Capture groups work too, so you can reference $1 or $2 in the Replace with field to reorder matched pieces.
How do I replace text online without worrying about letter casing?
Enable the Case-insensitive option. It adds the i flag to the underlying pattern, so searching for admin will also match Admin and ADMIN. Leave it off when casing carries meaning, like variable names in code.
Can I run a bulk find replace on thousands of lines at once?
You can. The replacement is applied globally in a single pass, and everything happens in your browser's memory, so even a large log dump processes instantly. There's no row limit beyond what your machine can comfortably hold in a textarea.
What does the Multiline checkbox change in a find and replace pattern?
It adds the m flag, which makes the ^ and $ anchors match at the start and end of each line rather than the whole input. It only matters when Regex mode is on and your pattern uses anchors.
Why does the match counter show 0 in the find and replace text tool?
Usually the search term doesn't exist with that exact casing, so try the Case-insensitive option. In plain mode, characters like . and * are escaped and matched literally, which surprises people expecting wildcard behavior. Turn on Regex if you want patterns.
Is my text uploaded anywhere when I find and replace online?
No. The matching and replacement run entirely in your browser with JavaScript, and nothing leaves the page. That makes it safe for customer exports and other data you'd rather not paste into a random server-side tool.
Can the find and replace text tool delete matches instead of replacing them?
Leave the Replace with field empty and every match is removed. It's a quick way to strip a repeated prefix, a tracking parameter, or boilerplate that appears throughout a document.
What happens if I type an invalid regex into the Find field?
An error message appears above the panes and the Result pane falls back to your untouched input. Fix the pattern, an unclosed bracket is the usual culprit, and the preview resumes on its own.
