A minified API response is nearly unreadable, and pasting one into an unknown formatter may hand over live user data. This parser runs locally and, when validation fails, points to the exact line and column rather than just reporting "invalid JSON". Large payloads render as a collapsible tree so you can drill down to the field you actually need.
Yes. It reports the line and column and highlights the offending character, which makes stray commas and missing quotes obvious.
Yes. A lenient parsing mode accepts comments and trailing commas, and exports clean standard JSON.
No. Parsing is entirely in-browser with no network requests, so responses containing sensitive fields are safe to paste.
