Hi,

LabVIEW cannot read a .xls file using the Read from Spreadsheet File VI- it will output an array of zeros, as yours is.  I would make a copy of the file and change the file extension to .lvm.  This type of file can be read into LabVIEW using the Read From Measurement File Express VI.  

Take a look at this KB:

[RavensFan]

This entire thread is very reminiscent of a recent thread in the LabVIEW board where he was told the same things.

Avinash,

If you want to get peaks, use Waveform Peak Detection or one of the other similar VIs.

If you want to find the base average, parse through the data you get from Excel and if it's below a certain range, add it to the total and divide by number of points.
