Airtable is a very cool tool on the verge of a spreadsheet editor and a database. And if one day you outgrow the capabilities of this service and want to move to a real PostgreSQL database, I have a simple solution for you.
Airtable-to-PostgreSQL Migration Tool will help you quickly migrate a table from Airtable to PostgreSQL database.
The service is so simple that all of its features fit in the screenshot above. On the left half, for moving, you are required to specify the API key, base ID and tables from Airtable that you want to transfer. And on the right is the data for connecting to your database. When you click on the Move button, all data will be transferred.
