Find and Replace

When to use Find and Replace

A content manager exported 3,000 rows of product descriptions as a single text file and every instance of the old brand name needs to become the new one before the import. Paste the content here, type the old name in the search field, the new name in the replace field, and click Replace All. Matches highlight as you type so you can verify scope before committing — useful when the search term appears in unexpected places. Toggle Regex on to run a JavaScript regular expression substitution instead of a literal string match, which handles patterns like normalizing phone number formats or stripping HTML tags. The substitution runs in your browser tab; nothing reaches a server. Copy the cleaned text and paste it wherever it needs to go.

• Swap an old brand name across a bulk product description export
• Strip HTML tags from a CMS export using a regex pattern
• Normalize inconsistent date formats in a pasted data file

About this tool

When your editor's find-and-replace isn't enough — or you're working with text outside of any editor — paste your content here and run targeted substitutions with regex support, case sensitivity toggles, and whole-word matching. Useful for normalizing a data export before loading it elsewhere, cleaning up inconsistent terminology across a long document, or testing a regex substitution pattern before wiring it into a script. Matches highlight as you type so you can verify scope before committing. Your text never leaves this page — no upload, no server, pure browser computation. Replace all at once or step through matches one by one.
