Regex Tester & Validator

This regex is designed to extract values from simple JSON-like structures by matching either a colon, a space, and a quoted string (capturing the string), or a standalone sequence of digits. It is commonly used in basic data parsing tasks to isolate text within quotes and numerical values without fully validating the JSON schema. While effective for basic extraction, it lacks the complexity to handle nested objects, arrays, or boolean/null values natively.
