Troubleshooting Tip: Manual malware IOC import using csv file failed with error 'Row 1, Column 2: Expected String format, Field is missing'

The import failed error indicates that format of the CSV file contents is incorrect.

CSV import failed due to missing comma separators. Each row in the CSV file must contain the required number of columns, even if some columns are blank.

For example, when importing URLs, the CSV file must contain five columns: URL, malware type, confidence, description, and last seen (mm/dd/yyyy)

Therefore, each row should have four commas, even if the columns other than the URL are blank.

Incorrect CSV file:

https://abc.local/unPek2 
https://xyz.local/setup_wm.exe 

Correct CSV file:

https://abc.local/unPek2,,,,
https://xyz.local/setup_wm.exe,,,,
