How to use, limits & privacy

Choose a UTF-8 JSON file and download a structure report. Root has the empty JSON Pointer; slash and tilde in keys are escaped. Values are omitted. Browser JSON.parse semantics apply: duplicate object keys collapse and numeric values may round. Limits: depth 80, 100,000 nodes and 2 million combined path characters. This analyzes structure rather than formatting JSON.

Text: UTF-8 only, 4 MiB; CSV: 50,000 data records, 200 columns, 500,000 cells; exports: 16 MiB.
