How can I pretty-print JSON using Go?

Does anyone know of a simple way to pretty-print JSON output in Go?

I'd like to pretty-print the result of json.Marshal, as well as formatting an existing string of JSON so it's easier to read.

MarshalIndent will allow you to output your JSON with indentation and spacing. For example:

{
    "data": 1234
}

The indent argument specifies the series of characters to indent with. Thus, json.MarshalIndent(data, "", " ") will pretty-print using four spaces for indentation.
