Hi Prasad,
The file you attached does not follow the format as described in Help:
samrepo.nrelcloud.org/help/weather_format_csv_wind.html
I made a couple of modifications in the attached version of your file to get it to work:
1. Put all header items in Row 1.
2. Copy the last few lines of data so that the last row ends with Hour 23 of December 31.
Best regards,
Paul.
