Use this JSON operation to transform or present valid JSON while preserving the intended values and structural relationships.

Document

Nested JSON object.

Flatten a JSON object into single-level dot-path keys pointing at primitive leaves. The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.^[1]

Flat map

Dot-path keyed leaf values.

• JSON does not represent comments, references, dates, binary values, non-finite numbers, duplicate-key meaning, or arbitrary object prototypes. Flattening requires an escaping convention, and pretty printing or minification does not validate application schemas.
• Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.

Parse and schema-validate untrusted data, document path escaping and collision rules, and round-trip transformed structures with representative edge cases.

• JSON Unflatten

  Rebuild a nested JSON object from dot-path keys, expanding numeric segments into arrays.

• JSON Patch Applier

  Apply a minimal RFC 6902-style add/remove/replace patch with RFC 6901 pointers to a JSON document.

• JSON Diff

  Produce a minimal deterministic RFC 6902-style add/remove/replace patch turning one JSON document into another.
