@pedrofigueira Using Excel? Do you know how to import CSV data? I used to use this steps, but on step 3 using "From other sources" option, and worked fine. I'm not on a machine with MS Office installed to test if there is any problem on the CSV file creation and on LibreOffice didn't looked around on how to do it.
