You cannot launched Excel without a connected desktop and other things.

You have two possible approaches. Either have your service start up its own login session, mount the appropriate registry hive and set up everything as it should be. Or, use Spreadsheet::ParseExcel, which does not need Excel to read a spreadsheet.

Update: Also, maybe use Spreadsheet::Read, which can read more than just Excel files.
