Thanks, it's an array... why ever... I need to use: writeln(j["a"][0]["b"]); Wasn't that obvious, because it's a big JSON structure. -- Robert M.

auto json_string = `{"a": {"b": 1}}`;
Results with your code as:
{"a":{"b":1}}
{"b":1}

Maybe your "a" value is not an object?

std.json / nested key/value access?
I have: JSONValue j = parseJSON(json_string).object; writeln(j);// works writeln(j["a"]); // works writeln(j["a"].object["b"]); // bombs Runtime error: std.json.JSONException@std/json.d(276): JSONValue is not an object How can I access a nested JSON key/value using something that comes close to a path notation? -- Robert M.
