JSON Unflatten
Rebuild a nested JSON object from dot-path keys, expanding numeric segments into arrays.
Description
Rebuild a nested JSON object from dot-path keys, expanding numeric segments into arrays.
JSON Unflatten: Rebuild a nested JSON object from dot-path keys, expanding numeric segments into arrays.
When to use JSON Unflatten
Use this JSON operation to transform or present valid JSON while preserving the intended values and structural relationships.
- Flat map
- Dot-path keyed leaves.
How JSON Unflatten works
Rebuild a nested JSON object from dot-path keys, expanding numeric segments into arrays. 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
- Document
- Rebuilt nested document.
Limitations and assumptions
- 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.
Alternative or Complementary approaches
Parse and schema-validate untrusted data, document path escaping and collision rules, and round-trip transformed structures with representative edge cases.
