Online JSON Formatter

This setting governs whether or not the Output is indented. The indented Output is easier to comprehend. On the other hand, a non-indented output is compact. The smaller size is best for transmission over the network. So, we often minify JSON by removing non-essential whitespace. Indentation is the primary use of this tool. Users paste minified JSON and try to debug it by formatting and indenting.

Indentation On

{
  "name": "John Doe",
  "age": 69
}

Indentation Off

{"name":"John Doe","age":69}

A valid JSON must have double quotes around the keys (or property names). Unless the keys include special characters, double quotes are unnecessary when used directly inside JavaScript. Turn off this setting if you want to omit quotes around keys.

Keys In Quotes On

{"name":"John Doe","age":69}

Keys In Quotes Off

{name:"John Doe",age:69}

Select this option to convert the casing of keys to lowerCamelCase, the default naming convention of JSON properties & JavaScript variables.

Camel Case On

{"personName":"John Doe"}

Camel Case Off

{"PersonName":"John Doe"}

Use this option only when cleaning a JSON structure because changing the keys will cause failures in applications that use this JSON format.

Braces are written on a new line (C# style) when this option is selected. Turning the option off puts the Braces on the same line (Java/JavaScript style).

Expanded Braces On

{
  "name": "John Doe",
  "age": 25,
  "addresses":
  [
    {
      "city": "Phoenix",
      "country": "Arizona"
    },
    {
      "city": "Miami",
      "country": "Florida"
    }
  ]
}

Expanded Braces Off

{
  "name": "John Doe",
  "age": 25,
  "addresses": [
    {
      "city": "Phoenix",
      "country": "Arizona"
    },
    {
      "city": "Miami",
      "country": "Florida"
    }
  ]
}

Use this setting to remove escape characters in JSON Formatter. It unescapes the input JSON by removing all backslash characters preceding a double quote. This removal is needed if your JSON input has been escaped and exists in the form of a string.

Input

"{\"personName\":\"John Doe\"}"

Remove Escape Characters On

{
  "personName": "John Doe"
}

Remove Escape Characters Off

"{\"personName\":\"John Doe\"}"

You cannot use this option along with Format Embedded JSON

When this option is selected, JSON embedded or escaped within string values is processed, expanded & converted to nodes.

Format Embedded JSON On

{
  "name": "John Doe",
  "age": 25,
  "addresses": [
    {
      "city": "Phoenix",
      "country": "Arizona"
    },
    {
      "city": "Miami",
      "country": "Florida"
    }
  ]
}

Format Embedded JSON Off

{
  "name": "John Doe",
  "age": 25,
  "addresses": "[{\"city\":\"Phoenix\",\"country\":\"Arizona\"},{\"city\":\"Miami\",\"country\":\"Florida\"}]"
}

Even though there is no standard for representing dates in JSON, two popular formats have emerged. The ISO Date Format is the most widely used. If you are using a .NET stack, quite possibly you are using the Microsoft Date Format.

ISO Date Format

{"systemTime":"2014-01-01T23:28:56.782Z"}

Microsoft Date Format

{"systemTime":"\/Date(1388618936782)\/"}

The custom quote character to use for wrapping string values and property names. You can choose between single quote ' and double quote "

Quote Character: "

{
  "name": "John Doe",
  "age": 69
}

Quote Character: '

{
  'name': 'John Doe',
  'age': 69
}
