Delete a top-level key

For the simple case where you want to delete a top-level key and value pair, provide the key name as the path.

Input

• object:

  Copy

  {
      "foo": 1,
      "bar": 2
  }

• path: foo

Output

• output:

  Copy

  {
    "bar": 2
  }

Specify a dot-delimited path

A path can also be used to specify a key within a subobject, using a dot to indicate the subobject.

Input

• object:

  Copy

  {
    "a": "one",
    "b": {
      "foo": 1,
      "bar": 2
    }
  }

• path: b.foo

Output

• output:

  Copy

  {
    "a": "one",
    "b": {
      "bar": 2
    }
  }

Use an index number

You can also use an index number to indicate the path of a list element inside an object. List references begin with an index number of 0.

To delete the bar key and value pair on the 7th element in a list found in the foo key, your path would be foo.6.bar.

The following example removes one option for a bakery menu. The path specifies the second list element (index number 1) for the topping key inside the object.

Input

• object:

  Copy

  {
    "type": "donut",
    "name": "Raised",
    "batters": {
      "batter": [
        {
          "id": "1001",
          "type": "Regular"
        }
      ]
    },
    "topping": [
      {
        "id": "5003",
        "type": "Chocolate"
      },
      {
        "id": "5004",
        "type": "Maple"
      }
    ]
  }

• path: topping.1

Output

• output:

  Copy

  {
    "type": "donut",
    "name": "Raised",
    "batters": {
      "batter": [
        {
          "id": "1001",
          "type": "Regular"
        }
      ]
    },
    "topping": [
      {
        "id": "5003",
        "type": "Chocolate"
      }
    ]
  }

Use a list of text as the path

The dot-delimited path is simple and powerful, but it may not work if your key names are numbers or include the dot character. In that case, you can control the path explicitly by using a list of text. Each item in the list is treated as a single key, without interpreting numbers or dots.

Input

• object:

  Copy

  {
    "a": "one",
    "b.foo": {
      "7": "bar",
      "8": "baz"
    }
  }

• path: use the dropdown menu to set the path as a list of text.

  • First entry: b.foo

  • Second entry: 7

Output

• output:

  Copy

  {
    "a": "one",
    "b.foo": {
      "8": "baz"
    }
  }
