About Text Replace
The Text Find & Replace tool lets you search for any string in your text and replace all occurrences with a single click. Whether you are cleaning up a log file, reformatting a CSV, or normalizing inconsistent capitalization across a document, this tool handles bulk replacements instantly without requiring any software installation.
Writers, developers, and data analysts all rely on find-and-replace workflows daily. This tool supports both plain-text matching and full regular expression (regex) patterns, so you can perform simple word swaps or complex pattern-based substitutions — for example, replacing all date formats or stripping HTML tags with a single regex. The replacement count is shown after each operation so you always know how many changes were made.
Everything runs entirely in your browser using the JavaScript RegExp engine. Your text never leaves your device and is never sent to a server. The case-sensitive toggle lets you control whether "Hello" and "hello" are treated as the same word. When regex mode is on, the tool accepts any valid JavaScript regular expression including capture groups and backreferences.

Frequently Asked Questions
What is the Text Find & Replace tool?
It is a free browser-based tool that searches your pasted text for a pattern and replaces every match with your specified replacement string. It supports both literal text and JavaScript regular expressions.
How do I replace all occurrences at once?
Paste your text in the input area, type what you want to find, type your replacement, then click "Replace All". Every match in the text will be replaced simultaneously and the count of replacements will be shown.
How do I enable regex mode?
Check the "Use Regex" checkbox. You can then enter any valid JavaScript regular expression in the Find field, such as \d+ to match numbers or [aeiou] to match vowels.
Can I do case-insensitive replacement?
Yes. Uncheck the "Case Sensitive" checkbox to make matching case-insensitive, so "Hello", "HELLO", and "hello" will all be matched and replaced.
What happens if I enter an invalid regex?
The tool catches the error and displays a clear error message below the controls. Your original text is preserved unchanged until you fix the regex pattern.
Can I replace text with nothing (delete it)?
Yes. Leave the Replace field empty and click "Replace All". Every match will be deleted from the text, effectively removing all occurrences of the search pattern.
Is this tool good for processing code or log files?
Absolutely. The text areas use a monospace font suitable for code and logs. You can paste thousands of lines and the tool processes them instantly in your browser without any size limits imposed by a server.
Does the tool save my text anywhere?
No. All text is held only in your browser memory for the current session. Nothing is uploaded to any server, stored in a database, or logged. Closing the tab clears everything.
