It seems Excel 2013 doesn\'t read CSV files correctly (Excel 2010 does). Every time I open .csv files, all my data are displayed in the first column.
I know I can go
Open the CSV file with a decent text editor like Notepad++ and add the following text in the first line:
sep=,
Now open it with excel again.
This will set the separator as a comma, or you can change it to whatever you need.
