The most important changes involve the addition of a timestamp to the…

… exported order sheet. This was achieved by creating a new variable, appending it to the sheet data, and adding a new cell with a formatted string indicating the current date and time.

Changes:
1. A new variable `timestamp` of type `Row` was added. This variable is crucial as it holds the timestamp data that will be appended to the order sheet.
2. The `timestamp` row was appended to `sheetData`. This step integrates the timestamp into the existing sheet data, ensuring it is included in the exported order sheet.
3. A new `Cell` was appended to `timestamp` with a `DataType` of `String` and a `CellValue` of a formatted string indicating the current date and time. The string states "This order sheet was exported on" followed by the current date and time in the format `yyyy-MM-dd HH:mm`. This change is the final step in adding a timestamp to the exported order sheet, providing a clear indication of when the order sheet was exported.
