JSON Fix: Autocorrect and Repair Malformed JSON

A Fix JSON Tool automatically detects and attempts to correct errors in malformed JSON. It's especially helpful when you're working with incomplete, broken, or messy JSON inputs and need a quick fix to make it parseable.

Why Use a JSON Fixer?

• Recover broken data: Useful when dealing with corrupted exports, copy-paste issues, or logs with partial JSON.
• Speed up debugging: Instantly clean and reformat invalid JSON to make it testable and parsable.
• Reduce manual editing: Automatically handles missing quotes, trailing commas, or unescaped characters.
• Fix while preserving structure: Attempts to preserve the intended data hierarchy during the correction process.

How to Use This Tool

• Paste your invalid or malformed JSON into the left editor.
• Click the “Fix JSON” button to apply automatic corrections.
• View the corrected and formatted JSON in the right editor.

The tool performs a best-effort recovery — it can often fix issues like unquoted keys, trailing commas, missing braces, or escape character problems. While not guaranteed to fix every issue, it’s an invaluable tool when dealing with messy or user-generated data.
