Find and Replace

What the Find and Replace tool does

This is a quick text swapping tool. You drop in a block of text, tell it what word or pattern to look for, type what should take its place, and it rewrites every match at once. It is handy for cleaning up copied content, renaming a term across a long document, fixing a repeated typo, swapping placeholders, or reformatting data pasted from a spreadsheet or email. Writers, students, developers, and anyone wrangling messy text will get use out of it.

Two checkboxes give you control over how matching works. Turn on Case insensitive to match a word no matter how it is capitalized. Turn on Use regex when you need pattern matching, for example replacing all digits with \d or trimming repeated spaces.

How to use it

1. Paste or type your text into the input box.
2. In the Find field, type the word, phrase, or pattern you want to locate.
3. In the Replace with field, type the text that should take its place. Leave it empty to simply delete every match.
4. Tick Case insensitive if capitalization should not matter.
5. Tick Use regex if your Find value is a regular expression.
6. Press Replace and copy the rewritten text from the output box.

Why do it here

Everything happens inside your own browser. Your text is never uploaded, so private notes, client copy, or code stay on your machine. There is no sign-up, no fee, and no limit on how often you run it. Results appear the instant you click, and it works the same on a phone, tablet, or laptop.

If you regularly need to find and replace across many documents at the same time, the BulkPro desktop app from the same team handles batch jobs like that.

Tip: an invalid regular expression will show an error, so if regex mode fails, double check your pattern or untick the box for a plain text swap.
