Can I choose which sheet to append to?

Yes, use the 'Target Sheet Name' field to specify exactly where the new rows should be added.

What is returned after processing?

You receive a ZIP file containing the updated Excel workbook and a JSON file that provides the latest cursor value for your next update.
