CSV file format requirements
- The file does not include column headings. Tableau Online assumes that every line in the file represents a user.
- The file is in UTF-8 format, and includes the byte-order mark (BOM).
- Character encodings such as BIG-5 have been converted to UTF-8. You can do this by opening the file in a text editor and using the Save As command.
- If a user name includes an @ character that represents anything other than a domain separator, you need to refer to the symbol using the hexadecimal format: \0x40 For example, user@email@example.com should be user\firstname.lastname@example.org
