How do I pretty-print JSON in Delphi? – Stack Overflow

Posted by jpluimers on 2021/02/09

For my archive: the [WayBack] How do I pretty-print JSON in Delphi? – Stack Overflow answer by [WayBack] Bob:

If you do not want to use any external library, and you’re using a Delphi XE5 or newer, there is a very handy TJson.Format() function in the REST.Json unit.

uses json, REST.Json;

{ ... }    

function FormatJSON(json: String): String;
var
  tmpJson: TJsonObject;
begin
  tmpJson := TJSONObject.ParseJSONValue(json);
  Result := TJson.Format(tmpJson);

  FreeAndNil(tmpJson);
end;

    I don’t know with older Delphi versions, but with Delphi 11 tmpJSON.Format will do the trick (REST.Json.Format calls TJONObject.Format internally)
