Flatten JSON into reversible RFC 6901 pointer maps and rebuild documents.
Use the guide alongside the working tool.
Open JSON Flatten & Unflatten →Working input
{"user":{"name":"Ada","roles":["admin"]},"empty":{}}Flatten JSON into reversible RFC 6901 pointer maps and rebuild documents. Pointer-map leaves include empty arrays and objects. Conflicting, sparse, unsafe or ambiguous paths are rejected rather than silently overwritten.
Input and purpose
Flatten JSON into reversible RFC 6901 pointer maps and rebuild documents.
Start with the working sample, then replace it with your own input. The sample input is: {"user":{"name":"Ada","roles":["admin"]},"empty":{}}
Review the result
Pointer-map leaves include empty arrays and objects. Conflicting, sparse, unsafe or ambiguous paths are rejected rather than silently overwritten.
Run processes the current input on your device. Changing an input clears the previous output so you cannot accidentally export stale results.
Copy and export
Copy or download only after reviewing the exact generated text. Nothing is applied to your project or sent to an endpoint.
Use Undo sample to restore your draft. Clear inputs or close the tab when finished; no content is stored in localStorage.
