@yukicchi626 bimorph nodes package has a node called Schedule.GetData, here is an example of using it in conjunction with writing to Excel:
And a link to the node definition:

If you want to be able to edit the data produced from that node in Excel, and then import it back into Revit via Dynamo, I recommend creating a parameter “Element ID” and putting that parameter as a field in your schedule. Then in Dynamo, collect all your elements that appear in the schedule, get their element IDs and set the new “Element ID” parameter value to the Element IDs, so when you read the data you can select elements by ID and update their info accordingly. I’d provide a graphic explanation to this but am not currently on a computer with Revit/Dynamo, but I hope this helps
