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
You can choose which separator you want in Excel 2013 Go to DATA -> Text To Columns -> Choose delimited -> then choose your separator "Tab, Semicolon, Comma, Space or other" and you will see changes immediately in the "data preview" then click FInish
Once you have the format that you wanted, you simply save the document and it will be permanent.
