Regex to String Converter

What Regex to String Converter does

Regex To String takes a regular expression — pattern plus flags, like /^[a-z]+\d*$/gi — and converts it into a plain string representation you can drop into JSON, a config file, or any language that doesn't support native regex literals. Paste your regex and it outputs the escaped pattern text with its flags separated out, all processed in your browser with no server round-trip.

How to use Regex to String Converter

1. Paste or type your regular expression, including the enclosing slashes and flags
2. The string representation appears instantly as you type
3. Review the escaped pattern and the flags listed separately
4. Copy the string output for use in your code or config file

Who should use it

Made for developers. Typical uses:

• Storing a regex pattern as a string field in a JSON config file
• Passing a regex pattern into a language or API that expects a string, not a native regex literal
• Debugging why a regex works in JavaScript but throws an error when pasted as a string elsewhere
