Synchronous Time Averaging from a data file

[elwgreen]

I am afraid again, I am not clear on the results I am looking for. I have attached a spreadsheet file that I hope will show you what I hope to end up with. I also attached the code I started with. The problem I see with the original code is that it reads the file over and over. It also was not writing the results as intended.

I finally made Labview rewrite the data like I wanted. I have attached the code as requested and a data file to read. There are 500000 data points in this file. I usually stop the VI after about 20 lines just to test it. It actually takes several minutes to read the entire file. There is one MAJOR problem and again I am lost. The VI writes trailing space to each cell. I have a huge spreadsheet of text that I cannot convert to numbers. I have tried Trim and other suggestions but it would be less time than just manually grabbing a few batches of data and averaging them manually in excel. If you know how to make the Set Cell Value.VI to write numbers instead of string text it would be greatly appreciated.
