What is the Find and Replace?
The Find and Replace tool searches your text for one string and swaps every occurrence for another. It supports case-sensitive matching and full JavaScript regular expressions when you need pattern-based replacements.
It is the quickest way to clean up recurring typos, mass-rename identifiers, or reformat a list without opening an editor.
Who is the Find and Replace for?
Writers fixing repeated typos, developers renaming identifiers in configs, support staff redacting sensitive strings, and analysts reformatting exports.
Why use the Find and Replace?
- Case-sensitive toggle for exact matching.
- Regex mode for advanced patterns.
- Live count of replacements made.
- Handles very long text without freezing.
- 100% client-side and private.
When should I use the Find and Replace?
- Fixing a company name that was misspelled throughout a document.
- Redacting email addresses with a regex pattern.
- Turning commas into tabs for a spreadsheet paste.
- Reformatting phone numbers using regex groups.
- Bulk-renaming variables inside a copied code snippet.
Is the Find and Replace safe and private?
Yes. This tool runs entirely inside your browser - your text is never uploaded, stored on our servers or shared with third parties. You can even disconnect from the internet after the page loads and it will keep working. That makes it safe for confidential notes, drafts, private messages and unpublished work.
How do I get the best results from the Find and Replace?
- Always test the search term on a small sample first.
- In regex mode remember to escape special characters like . and *.
- Use empty replacement text to delete every match.
- Preview the result before overwriting your source document.
