## Notes

- Only `.xlsx` files are supported (not legacy `.xls`)
- Use path-based access (`/drive/root:/{path}:`) or ID-based access (`/drive/items/{id}`)
- Table/worksheet IDs with `{` and `}` must be URL-encoded
- Sessions improve performance for multiple operations
- Sessions expire after ~5 minutes (persistent) or ~7 minutes (non-persistent)
- Range addresses use A1 notation
