Importing CSV file to adalo collections(failing)

Hello, anyone can help me importing DB to adalo?
My teammate was able to import the DB before but when I tried it now, it was unsuccessful. it creates one line after it prompt that it failed. I tried importing a only 1 data csv file and still it doesn’t work. hope anyone could help asap.

DB that I want to import on books collection - MPV test - Google Sheets

Hi Jen,

I’m not sure the problem, but something that might be worth a shot. On the first record you are importing, try making sure all fields are populated. In your dataset the last 2 fields are empty for the first record, so try putting example data in there and seeing if it makes a difference.
