I encountered the same issue.

I feel the simplest way is to convert the CSV file to a JSON file using an online tool and then import.

This is the tool I used:

http://www.convertcsv.com/csv-to-json.htm

It lets you wrap the integer values of your CSV file in double quotes for your JSON file.

If you have trouble importing this JSON file and encountering an error, just add --jsonArray to your import command. It will work for sure.

mongoimport --host localhost --db mydb -c mycollection --type json --jsonArray --file
