Hello, I am fairly new to AutoIT so please bear with me. I just can't understand the _Excel functions and I have been spending hours to do this. So far, this is what I have done. I created an excel file using the typeperf.exe in windows to monitor its cpu usage with 60 samples in 5 sec interval. I managed to create an excel file and right now I need to average its results in which I am very unsuccessful. I understand that I first need to open the excel file if I already have one via _Excel_Open. e.g. _Excel_Open("C:\sample.csv). After that, what do i actually do? I've also seen _ExcelWriteCell and I don't think it's the command I need. Thanks, Ivan
