The first step is to select the CSV file and determine the application you want to import it to. Bubble.io provides an easy upload interface for users to upload their CSV files.

Next, you need to determine the data types to match the data. For example, if a CSV file contains customers' names, last names, and email addresses, you need to match this data with the relevant data types in your application.

To do this, create data types in the Bubble.io platform and match the columns in the CSV file with these data types. When the matches between the data types and columns are done correctly, the data in the CSV file is automatically uploaded to the application, and users can access this data.

Bubble.io's CSV import and data matching features allow users to save time and automate the import of data instead of manually entering it. These features help businesses manage their data more quickly and efficiently.
