Regex Editor & Tester

Matches the value of a "token" key in JSON-formatted text using a lookbehind for `"token":"` and a lookahead for the closing quote. The `[^" ]`... actually `[^\"]+` captures the token value, which cannot contain double quotes. Typically used in editors or scripts to find and replace token values in config files, API responses, or test fixtures without modifying the surrounding JSON structure.
