I have a table in Perspective where data is bound to an array at `view.custom.tableData` which contains records formatted like the snippet at the end.

Do I need to convert this dataset type before I can use `system.dataset.toExcel()`? I'm getting nothing from this.

Button onActionPerformed:

```python
def runAction(self, event):
	dataset = self.view.custom.tableData
	download = system.dataset.toExcel(1, dataset, "All")
	
	system.perspective.download("Inventory.xlsx", download)

```

Example record in dataset `view.custom.tableData`...

```python
[
  {
    "IsWS": false,
    "Online": true,
    "NameRegister": 101,
    "nodeID": "001",
    "deviceID": "Trk01"
  }
  ...
]

```

Yes, because lists of objects are not datasets. Consider supplying the table with a true dataset for `props.data`.
