Ultimate Guide: Replacing Letters and Text

Manually searching and replacing multiple strings is tedious. Our bulk text replacer allows you to define multiple replacement rules and apply them instantly. Perfect for coding, data cleaning, and text formatting.

For Developers

Refactor code by renaming multiple variables at once, obfuscate email addresses, or clean up JSON/CSV data. The Regex support gives you unlimited power for pattern matching.

For Content Creators

Correct common spelling mistakes, change regional spellings (e.g., color vs colour), or anonymize personal data in documents with a single click.

Pro Tip: Regular Expressions

Enable the "Regex" toggle on any rule to use JavaScript Regular Expressions. For example, use \d+ to match any number, or ^Hello to match "Hello" only at the start of a line.
