How it works
Convert in three steps

Paste your text

Add any content into the text field — a document, article, code block, or data export.

Enter your search and replacement

Type what you’re looking for in the Find field and what to replace it with in the Replace field. Toggle case sensitivity, whole-word matching, and regex mode as needed.

Replace all or step through

Click Replace All to swap every instance at once, or use Replace One to step through each match individually and confirm.

Common questions

Yes. Toggle regex mode to use full regular expression patterns in the Find field. The replacement field also supports backreferences to capture groups — $1, $2 — so you can restructure matched content rather than just replacing it with a fixed string.

With whole-word matching enabled, the tool only finds the search term when it appears as a complete word — surrounded by spaces, punctuation, or text boundaries. For example, searching for “cat” with whole-word matching won’t match “catch” or “concatenate” — only standalone occurrences of “cat.”

Yes. It’s well-suited for cleaning CSV exports, fixing formatting in text data, replacing old brand names across a document, standardising terminology, or removing unwanted characters across a large block of text.

No. All find and replace operations run in your browser. Your text never leaves your device.

About the Find & Replace Tool

Find and replace is one of the most-used text editing operations — renaming a term throughout a long document, fixing a recurring typo, cleaning a data export, or restructuring formatted content. Most text editors have it built in, but this standalone version adds regex support, whole-word matching, and case sensitivity controls in a lightweight browser tool that doesn’t require opening a full editor. Paste any block of text, configure your search, and get the result immediately.
