What this tool is for
JSON Diff Checker normalizes two JSON values before showing line-level differences.
When to use it
Use it when API responses or config objects look similar but one field changed.
What the result means
The result is a formatted JSON diff after both sides parse successfully.
Use notes
- Both inputs must be valid JSON.
- The comparison is text-based after formatting.
- Array ordering still matters.
