Typed JSON Pointer flattener online

Represent nested JSON using explicit typed pointer records. Container records preserve empty objects and arrays; this format is not a generic dotted-key flat object.

How to use it

Enter the source input or select Try example. Review the displayed input. Select Run tool and inspect the result before copying or downloading.

Worked examples

Represent nested JSON using explicit typed pointer records.

Worked example — Flatten JSON with Paths

Settings: No additional options

Input:

{"user":{"id":"00123"},"tags":["a","b"]}

Output:

[
  {
    "path": "",
    "kind": "object"
  },
  {
    "path": "/user",
    "kind": "object"
  },
  {
    "path": "/user/id",
    "kind": "value",
    "value": "00123"
  },
  {
    "path": "/tags",
    "kind": "array"
  },
  {
    "path": "/tags/0",
    "kind": "value",
    "value": "a"
  },
  {
    "path": "/tags/1",
    "kind": "value",
    "value": "b"
  }
]

The example returns 6 top-level items in an array. Each item is a record; the first record contains “path”, “kind”.

Choose the right tool

The output is a typed path-entry representation with container records. Rebuild Flattened JSON expects this representation; it is not an arbitrary dot-separated property map.

Limitations and common mistakes

Container records preserve empty objects and arrays; this format is not a generic dotted-key flat object.
