[EnergyPlus_Support] Re: Problem in converting a csv/txt file in an epw file

How do I modify a weather (EPW) file with other data?

The easiest way is:
1) run the weather converter on the original file
2) convert the file to "EnergyPlus CSV"
3) open the EnergyPlus CSV file in your favorite spreadsheet program.
4) make the mods, saving it as CSV from the spreadsheet program.
5) run the weather converter again, this time selecting the CSV and make sure the File type is "EnergyPlus CSV"
6) convert it to EPW.

if your regional settings aren't like US, you could run into a couple of problems, such as the spreadsheet program changing the DataPeriods line from 1/1, 12/31 to 01-Jan -- you'd need to hand edit that before step 5

I think you didn't use step 2 - override the default csv file in the weather converter with "EnergyPlus CSV".
