```d
// option 1
     string[string] aa_data;
     foreach(string k, v; data) {
         aa_data[k] = v.get!string;
     }
// option 2
     import std.algorithm : map;
     import std.array : assocArray;
     import std.typecons : tuple;
     auto aa_data = data.object
         .byKeyValue
         .map!(kv => tuple(kv.key, kv.value.get!string))
         .assocArray;
```

I personally prefer the straightforward loop.
