Data & developer
JSON Flatten / Unflatten
Converts objects and arrays to RFC 6901 JSON Pointer paths or rebuilds nested data from a flat path map. Key escaping is preserved and duplicate or conflicting paths produce explicit errors.
✓ Free✓ No account✓ In-browser
Persistent storage
Input and output are not stored. The optional usage counter keeps only tool identity and count, never content.
Verification
Output comes from disclosed rules or browser APIs and needs independent review before high-impact use.
A result in three steps
- 01
Enter valid nested JSON or a flat JSON Pointer map.
- 02
Choose flatten or unflatten and run the operation.
- 03
Verify array types and empty containers with representative samples.
When is this tool useful?
- ✓ Preparing configuration diffs
- ✓ Exposing fields for tabular export
- ✓ Inventorying deep API fields
Important limitation
Automated output is a preliminary assessment. Do not use it alone for legal, financial, medical, or security-critical decisions.
