Returns pretty printed JSON for the given JSON text.
See also JSON.Compact to get a compact format.


Format some object:

Set Variable [$json; Value:MBS( "JSON.Format"; "{\"Hello\": \"World\"}" )]
Show Custom Dialog [$json]

Parse some JSON, display it formatted and release:

Set Variable [$json; Value:MBS( "JSON.Parse"; "{\"Hello\": \"World\"}" )]
Show Custom Dialog [$json; MBS("JSON.Format"; $json)]
Set Variable [$r; Value:MBS( "JSON.Release"; $json)]

Format various JSON entries:

MBS( "JSON.Format";
\"Hello\": \"World\",
\"num\": 123,
\"value\": 123.456,
\"object\": {\"Hello\": \"World\"},
\"empty\": null,
\"array\": [1,2,3]}")

Example result:
{ "Hello": "World", "num": 123, "value": 123.456, "object": { "Hello": "World" }, "empty": null, "array": [1, 2, 3] }

Colorize and format in Auto-Enter calculation:

Let ( [
jsonFormatted = MBS("JSON.Format"; Self);
jsonFormatFailed = MBS("IsError");
jsonText = If(jsonFormatFailed; Self; jsonFormatted);
result = MBS("JSON.Colorize"; jsonText)
]; result )

// put this calculation into a field, so the field gets formated and colorized whenever the field is changed and the record gets commited.

Format JSON removes unicode escapes:

MBS( "JSON.Format"; "\"\uD83C\uDF4E\"")

Example result: "🍎"
