What is a JSON Diff Tool?
A JSON diff tool compares two JSON (JavaScript Object Notation) objects and identifies the differences between them. It shows you what was added, removed, or changed at each path in the JSON structure.
Common Use Cases

- Configuration Management: Track changes in config files.
- AI Response Comparison: Compare JSON outputs from different AI models.
- Data Validation: Verify data transformations are correct.
- Version Control: See what changed between data versions.
Difference Types
- Added (+): Keys or values that exist in the modified JSON but not in the original.
- Removed (-): Keys or values that exist in the original JSON but not in the modified.
- Changed (~): Keys that exist in both but have different values.
