JSON Formatter & Validator
The JSON Formatter was designed to assist users with debugging JSON data. Since JSON is often output without line breaks to conserve space, it can be challenging to read and interpret. This tool addresses that issue by formatting and beautifying JSON, making it more accessible and easier to debug.
To enhance its debugging features, advanced JSON validation was introduced, adhering to the guidelines set by Douglas Crockford of json.org in RFC 4627. It has since been updated to support multiple JSON standards, including the latest specifications of RFC 8259 and ECMA-404.
Recently, functionality to fix common JSON errors was added. When activated, this feature corrects issues like incorrect quotes, adds missing quotes, rectifies numeric keys, converts literals to lowercase, escapes unescaped characters, and removes comments and trailing commas.
