To open a CSV file correctly, first open Excel and create a blank workbook.
Select “Data“ in the ribbon.
Click on “Get Data“ > "From file" > "From Text/CSV" in the ribbon.
Select the file you want to open.
In the newly opened window select the file origin and delimiter: in order for all special characters to be displayed correctly and the data be separated, as shown in the pictures below (for a “recipients” file the file origin is “65001: Unicode (UTF-8)” and “Comma” as delimiter).
"Load" and done!

Note: If the volume of data is high, it may take a little longer to open.
You can easily open CSV files with other programs. For example, a Google spreadsheet (new spreadsheet > import > search file > import > ready) or free providers such as Moderncsv.com are also suitable.
