Run Command to open csv file in excel

If you include the Office directory that contains Excel.exe, then you don't need to explicitly set the path in your command line. The simplest thing to try is just type excel.exe and the CSV file name after it.

Otherwise, you will have to set the path explicitly. Using double quotes for excel and double quotes for the CSV is best:

"c:\program files\microsoft office\office12\excel.exe" "c:\newfile.csv"
