ABOUT
About JSON Repair
Paste a log line, a truncated object, or two JSON values stuck together. This page tries to recover a document you can copy.
Formatter already formats valid JSON and can Auto Fix on that page. Use this page when the search intent is Repair / Fix, not Beautify / Validate.
Recovery covers trailing commas, a JSON object hidden after a log prefix, concatenated values, and missing closing braces.
Samples use order A-1042 and lookup_order. This is not Schema validation and not a full JSON5 rewriter.
JSON Repair
Log slice
Skip text before the first recoverable { or [.
Truncated
Close leftover braces and brackets.
Concatenated
Two values in a row become an array.
Trailing comma
Strip a comma before a closer.
Not Validator
Schema checks stay on Schema Validator.

Does Auto Fix stay on Formatter?
Yes. Formatter keeps Auto Fix and links here.
Do you upload the payload?
No.
What can you fix?
Log prefix, trailing comma, concatenated values, truncated braces.
JSON5 comments?
Formatter JSON5 mode still handles comments on that page.
Schema errors?
Use Schema Validator. Repair only recovers syntax.
