This Commented CUE demonstrates how to use the built-in function encoding/json.Indent to transform JSON from a compact, single-line form held in a string into JSON with insignificant whitespace added that makes it easier for humans to read.

package example

import "encoding/json"

// See Related content, below, for documentation
// of json.Indent's 3 arguments:
//   func Indent(src []byte, prefix, indent string)
indent:     json.Indent(jsonString, " ", "  ")
jsonString: #"{"a":1,"b":{"c":"two","d":3.0},"e":false,"f":[4,5.0,"A\nMulti\nLine\nString"]}"#

$ cue export -e indent --out text
{
   "a": 1,
   "b": {
     "c": "two",
     "d": 3.0
   },
   "e": false,
   "f": [
     4,
     5.0,
     "A\nMulti\nLine\nString"
   ]
 }
