Write/Insert a row to an Excel Spreadsheet?

Hi. 

Is it possible to write a row (to the bottom) of an Excel spreadsheet from Creatio?

We need to copy select data from a Creatio screen to a row on a spreadsheet.  In our case, the spreadsheet lives on a Sharepoint drive.   The goal is for the user to push a button on a Creatio screen, and have it insert data to the last row of an existing spreadsheet.

Any direction or suggestions you have are appreciated.
Thanks!
