Wow, thank you for all the response. It is quite an headache to try do something quite simple. I may consider using a comma delimited file instead... Still working my possibilities. Thanks for the suggestions, FrankB and thank you for the code revision, ooth... It's very clear what I did wrong.
I have been trying to use ActiveX classes and write to multiple excel sheets. I was able to create a new workbook but it seems like I keep on getting a run-time error... Error 98 occurred at Unknown System Error in ExcelWritingDataToMultipleSheet.vi Possible reason(s): LabVIEW: Incorrect file type. Attempted to read from or write to a file of a type incompatible with the operation. This normally is a user data file. I don't really understand the concept of variant types. If somebody can point out how to fix this, that would be great... Thank you. ExcelWritingDataToMultipleSheet.vi
