Does JSON preserve/guarantee property order?

Hi. I’m sending json to storage via WriteStorageObjectAsync. But when this json is uploaded it has incorrect lines order.
It is important because I’m using typed objects parced in json.

For example I sending this json

{
    "IsInteractive": true,
    "OpenLevel": 0,
    "IsEmmpty": false,
    "CellItem": {
      "$type": "Funcraft.Merge.CellItem, GameModel",
      "Id": 20,
      "IsVisible": true,
      "Attributes": [
        {
          "$type": "Funcraft.Merge.Draggable, GameModel"
        },
        {
          "$type": "Funcraft.Merge.Mergable, GameModel",
          "Level": 3
        },
        {
          "$type": "Funcraft.Merge.Chest, GameModel",
          "_dropStep": 0,
          "IsOpened": false
        },
        {
          "$type": "Funcraft.Merge.StorehouseItem, GameModel"
        }
      ]
    },
    "Column": -25,
    "Row": 0,
    "Position": {
      "x": -25,
      "y": 0,
      "z": 0,
      "magnitude": 25.0,
      "sqrMagnitude": 625
    }

but really uploaded json looks like

{
      "Row": 0,
      "Column": -25,
      "IsBusy": false,
      "CellItem": {
        "Id": 20,
        "$type": "Funcraft.Merge.CellItem, GameModel",
        "IsVisible": true,
        "Attributes": [
          {
            "$type": "Funcraft.Merge.Chest, GameModel",
            "IsOpened": false,
            "_dropStep": 0
          },
          {
            "$type": "Funcraft.Merge.StorehouseItem, GameModel"
          },
          {
            "$type": "Funcraft.Merge.Draggable, GameModel"
          },
          {
            "$type": "Funcraft.Merge.Mergable, GameModel",
            "Level": 3
          }
        ]
      },
      "IsEmmpty": false,
      "IsLocked": false,
      "Position": {
        "x": -25,
        "y": 0,
        "z": 0,
        "magnitude": 25,
        "sqrMagnitude": 625
      },
      "OpenLevel": 0,
      "IsInteractive": true
    }

Line with $type must be on the first place, otherwise object will not be deserialized

Hi @antonsedov,

Unfortunately JSON only preserves the order of array elements, not of object properties.

Please see the JSON spec for more information (JSON), specifically:

An object is an unordered set of name/value pairs.
