Download the sample 10 Column CSV file
Sign in to Airtable
Create a new base
Click on Add or Import
Choose CSV file
Select the 10 column CSV file that you downloaded in the first step and upload the CSV file
Import the file into the base
The first row is the Header row
Now you can modify the content according to your requirements (don’t make any changes to the header)
Sometimes, Airtable tries to use the Single Select as the data type for the columns. Change it to plain text – either Single line Text or Multiline text (depending on the column). This will make it easier for you to do your updates, and will not affect the converter tool.
Once you have made your updates Download it as CSV and use it in the 10 column CSV converter.
