CSV is a text file, but its format is easy to import into excel, and xls is a table file, a set of things from Microsoft.
If you export the .xls excel file directly, fields of languages like Chinese needs to be transferred, otherwise it will be garbled when you open it. The structure of this table is the encoding of utf8.
