jsonmin

Show the structure of any JSON document and generate copy-pasteable jq paths. Useful for large API responses during pentesting or development.

• Color-coded tree: keys, types, array lengths, sample values
• --paths: flat list of jq leaf paths
• Handles nested objects, mixed-type arrays, primitive roots
• Auto-quotes unsafe jq keys (GUIDs, spaces, dots, etc.)
• Reads from file or stdin — zero dependencies (Python 3.8+ stdlib)

Examples

# tree view
jsonmin.py response.json

# flat jq paths
jsonmin.py --paths response.json

# pipe from curl
curl -s https://api.example.com/data | jsonmin.py --paths

Root: object

  id           string    "a3f9c..."
  name         string    "John Doe"
  active       boolean   true
  tags         array(3)
    [0]        string    "admin"
  address      object
    city       string    "Springfield"
