Build, test, and debug regular expressions
Matches simple JSON key-value pairs by capturing a quoted key followed by a colon and its value. The first group captures the key between double quotes, the second captures the value after optional quotes, stopping at commas, braces, or quotes. Useful for quick flat JSON data extraction, but fails on nested objects, arrays, or escaped characters.
