    How this tool works

    jsonrepair attempts structural fixes (commas, brackets, quotes) without a round trip to a server. If it succeeds, the repaired text is valid JSON you can copy or open in other toolkit pages. Issue chips summarize what was adjusted when the library reports them.

    Tips

    • Try gallery examples first to see typical fix patterns.
    • Garbage or truncated logs may still fail—trim to the JSON substring and retry.
    • After repair, run Format or Validate to confirm structure for your pipeline.
    • Automated repair can change meaning (e.g. quoting)—review diffs for production data.
