About Text Replacement Tool
The Text Replacement Tool lets you find and replace words, phrases, or patterns across any block of text instantly — right in your browser, with no software to install. Whether you need to swap one word for another across a long document, apply bulk changes using regular expressions, or do a case-sensitive search for exact matches, this tool gets it done in seconds.
Find and replace is one of the most fundamental editing operations in any text workflow. Manuscript writers who decide to rename a character after writing fifty pages need to update that name throughout. Marketers rebranding a product need to replace the old name in every piece of documentation. Developers maintaining templates need to swap placeholder strings with real values before deployment. Content editors cleaning up scraped web text often need to remove specific phrases or patterns in bulk. All of these tasks are tedious and error-prone when done manually — the Text Replacement Tool automates them completely.
The tool supports three matching modes: plain text replacement (the default), case-sensitive matching to target only exact instances of a specific capitalization, and regular expression mode for advanced pattern matching. Regex mode is particularly powerful: it lets you match and replace structured patterns like phone numbers in a specific format, URLs with certain domains, dates written in a particular style, or any custom pattern you can express as a regex.
Bulk replacement processes every instance in a single pass — you are not clicking “Replace Next” fifty times. Paste your text, define your find and replace terms, and the updated content is ready to copy.
All text processing happens entirely in your browser using JavaScript. No content is transmitted to any server, stored, or logged — making this tool safe to use with proprietary documents, confidential content, and sensitive text of any kind.
Free, instant, no account needed, and available on any device.
