What is find and replace text?

A find and replace tool locates every occurrence of a target word or phrase in a piece of text and substitutes it with a replacement you choose. Paste your text, type what to find and what to replace it with, and the result updates in real time. Beyond simple word swaps, two options make this genuinely powerful: a case-sensitive toggle that only matches exact capitalization, and a regex (regular-expression) mode that lets you match patterns instead of literal text. With regex you can find every email address, phone number, date format, or repeated word in one operation and replace them consistently. This is valuable when you are editing copy, cleaning up generated content, normalizing data, or changing a name or term across hundreds of lines at once. The corrected result stays in its own pane so you can review it before copying.

How to use

Enter the word or phrase to find and its replacement.
Paste your text.
The corrected text appears instantly — copy it.

Example

Find the word color and replace it with colour on a block of US English text. Every instance switches instantly; tick Case-sensitive so Color and COLOR stay untouched while color is replaced.

Common use cases

Changing a name, brand term or typo across a whole document at once.
Normalizing US to UK spelling, or converting a value to a different unit or format.
Cleaning messy text with regex: find all numbers, emails or URLs and replace them.
Fixing repeated phrases or placeholder tokens in templates and generated copy.

Pro tips

Enable Case-sensitive for exact-capitalization matches, or leave it off for a broad search.
Use regex mode to match patterns — for example \d+ for any number or a URL pattern for links.
The result pane is read-only and always stays in sync, so you can Paste and check before copying.
Remember that regex metacharacters like . * + ? ( ) [ ] are treated literally unless regex mode is on.

FAQ

How do I find and replace text?

Paste your text, enter the word or phrase to find and its replacement, and the corrected text appears instantly in the result pane — copy it when ready.

Can I use regular expressions?

Yes. Enable the regex checkbox to match patterns like email addresses, dates or repeated words instead of exact text.

What is the difference between case-sensitive and case-insensitive?

Case-sensitive only replaces text that matches the exact capitalization you typed; case-insensitive replaces all forms, so color matches Color and COLOR too.

Is it private?

Yes — it runs entirely in your browser and nothing is uploaded.

Does it replace every occurrence or just the first?

Every occurrence across the text is replaced by default; use regex with specific anchors to limit matches if needed.

Can I see what changed?

The input and result appear side by side, so you can visually compare and review the difference before copying.

Is it free?

Yes, free and unlimited with no signup and no limits.

How do I revert a change?

Keep your original text in a separate place, or press Clear and re-paste it; there is no undo history.
