What is the difference between JSON formatting and validation?
Formatting improves readability. Validation confirms syntax or schema rules. Debugging API payloads often needs both.
Why convert JSON5 to standard JSON?
Draft configs may allow comments or trailing commas, but most APIs and databases require standard JSON before release.
