How to use this tool

  1. Enter flat json object.
  2. Select Update result to view the result.
  3. Check the method and assumptions below before using the result.

The method, explained

Split each key on dots and create nested objects. Reject paths that conflict with an existing value.

A WORKED EXAMPLE

{"user.name":"Ava"} becomes {"user":{"name":"Ava"}}.

What to keep in mind

Dotted numbers remain object keys, not array indexes. Unsafe and conflicting paths are rejected.
