Hi Fonsi,

System Exec.vi will allow you to run commands like launching a program easily but it is difficult and many times not possible to execute commands within an application.

A better way maybe to approach this though ActiveX. Please look at the following example that uses ActiveX to communicate with Excel.
Writing Rows to Excel 97 and Excel 2000 Using ActiveX

If you are not familiar to ActiveX and LabVIEW, please read the document below:
ActiveX and LabVIEW

I hope this
helps.
