How json flattener works
Converts nested JSON leaves into JSON Pointer paths. Slashes in keys become ~1 and tildes become ~0, preventing ambiguous paths. Empty containers are preserved.
Try an example
{"person":{"name":"Alex"}} becomes {"/person/name":"Alex"}.
Good to know
Processed in this browser. Maximum 100,000 input characters and 10,000 records. JavaScript JSON parsing can round large numbers and keeps the last duplicate key; quote identifiers to preserve them. Maximum nesting: 50. Array indices are path segments. The root primitive uses an empty path. This is JSON Pointer output, not dot notation.
