It's likely an error in the CSV file. Are you manually generating it or doing a File > Save As and changing the type to CSV. In Excel, the type is CSV UTF-8 (Comma delimited) (*.csv). There is also a CSV without the UTF-8 that can be used if you don't have any utf-8 characters (things outside the normal letters, numbers, and basic symbols) like emojis or some international characters.
If you're manually generating the file, here are some basics.
- Commas are used to separate fields (spreadsheet cells) and each row in the spreadsheet is a row in the CSV file.
- Wrapping each cell in double quote marks " is optional and typically not done. There are three exceptions -- see next item.
- If you have a comma, double quote, or line terminator within a field, then you need to wrap the cell with double quotation marks ".
- If you have quotation marks " within your cells, then you need to escape them by double quoting them and putting a quotation mark at the beginning and end of the cell.
For example, if you had the text: This is "awesome", then you would need "This is ""awesome""". The triple " at the end is the double "" for the " that is part of the text and then another " to end the quoted cell.
If you save your rubric as a CSV file from a spreadsheet, it should take of all that for you.
There is a potential issue with UTF-8 encoding depending on your locale. There are several export/import related feature options under your (personal) Account > Settings in Canvas.
