Find and Replace Text
Find and replace text with regular expression support. Replace multiple patterns in bulk in your text.
Everything about the find and replace tool
Why use an online find-and-replace tool?
Changing a recurring term in a 10,000-word document by hand is tedious and error-prone. An automated replacement tool processes every occurrence in one operation, eliminating missed instances and typos.
Regular expression (regex) support unlocks powerful patterns: standardize phone numbers, normalize dates, strip HTML tags — tasks impossible with a simple Ctrl+H.
Your text stays on your device. No data is sent to any server — replacement runs entirely in your browser via JavaScript.
Use cases
- Developers
- Rename a variable or CSS class in a pasted code block, with or without regex, before integrating it into your project.
- Writers and translators
- Replace a technical term with its translation throughout a document, in case-sensitive or case-insensitive mode.
- Data managers
- Clean CSV exports by replacing separators, removing extra quotes, or normalizing date formats with regex.
- Students
- Fix a repeated typo in your thesis: replace it everywhere in a single click with the 'Replace all' option.
How does the tool work?
Paste your text into the input area, enter the search pattern in the 'Find' field and the replacement text in 'Replace with'. Click 'Replace' to execute.
Three options are available: 'Use regex' for JavaScript regular expressions, 'Case insensitive' to ignore capitalization, and 'Replace all' to process every match or just the first one.
After replacement, the result displays with a counter showing how many occurrences were changed. Copy the output in one click.
Frequently Asked Questions
- How do I use regular expressions?
- Enable the 'Use regex' option, then enter a valid JavaScript pattern. For example, \d{4} matches 4-digit sequences, and [A-Z][a-z]+ matches words starting with a capital letter. The g (global) and i (case-insensitive) flags are controlled by the checkboxes.
- What happens if my regex is invalid?
- The tool displays a detailed error message describing the issue. No replacement is performed until the pattern is corrected, protecting your original text.
- Can I replace only the first occurrence?
- Yes, uncheck the 'Replace all' option. Only the first match found will be changed; the rest of the text stays intact.
- Is my text sent to a server?
- No. Replacement runs entirely in your browser. No data is transmitted, stored, or logged.
