Fmt is a helpful Slack bot for formatting JSON messages 🙃

Slash command /fmt [spaces] json.

Usage

Simply type

/fmt {"people": [{"name": "Ben"}, {"name": "Sam"}, {"name": "Rebecca"}]}

and Fmt will respond with the JSON properly formatted.

{
  "people": [
    {
      "name": "Ben"
    },
    {
      "name": "Sam"
    },
    {
      "name": "Rebecca"
    }
  ]
}

By default Fmt will indent with two spaces. To change this, just enter the number of spaces you'd prefer before the JSON string.

/fmt 4 {"a": ["one", "two", "three", "four"]}

{
    "a": [
        "one",
        "two",
        "three",
        "four"
    ]
}

Fmt can also handle relaxed JSON, thanks to the jsonic library.

You can find the rules for relaxed JSON here, but they are repeated below too.

• You don't need to quote property names: { foo:"bar baz", red:255 }
• You don't need the top level braces: foo:"bar baz", red:255
• You don't need to quote strings with spaces: foo:bar baz, red:255
• You do need to quote strings if they contain a comma or closing brace or square bracket: icky:"_,}]_"
• You can use single quotes for strings: Jules:'Cry "Havoc," and let slip the dogs of war!'
• You can have trailing commas: foo:bar, red:255,

For example

/fmt cats: [socks, spice, scratch, mister purrfect]

{
  "cats": [
    "socks",
    "spice",
    "scratch",
    "mister purrfect"
  ]
}

/fmt 4 cast: [{name: Belinda Blumenthal, job: Worldwide Sales Director of Steele's Pots & Pans}, {name: Ken Dewsbury, job: Central and Northern England RSM }]

{
    "cast": [
        {
            "name": "Belinda Blumenthal",
            "job": "Worldwide Sales Director of Steele's Pots & Pans"
        },
        {
            "name": "Ken Dewsbury",
            "job": "Central and Northern England RSM"
        }
    ]
}
