Yes, Airtable offers you the ability to manually upload/import CSV files or manually upload/import Excel files into your existing bases and tables.

The most powerful way to do this is by using CSV files, and using Airtable’s CSV Import extension.

However, are you asking if you can automate the process of uploading CSV files into Airtable?

If you want to automate the process of importing CSV files into Airtable, you would need to turn to Make’s Airtable automations and Make’s CSV automations.

I give a full step-by-step training on how to automate the process of automatically importing CSV files into Airtable on this Airtable podcast episode: Automate the process of importing CSV files into Airtable.

If you’ve never used Make’s automations & integrations before, I offer even more training resources in this thread.

Yeap, there's a couple of ways!  Check out Airtable's documentation on how to import CSVs: https://support.airtable.com/docs/google-sheets-importer#importing-csv-files-into-airtable

Their CSV Extension: https://support.airtable.com/docs/csv-import-extension

And the Sync API: https://support.airtable.com/docs/airtable-sync-integration-sync-api

The Sync API is not a recommended approach because it creates "read-only tables" in Airtable where users are unable to edit the data in Airtable.
