Airtable Importer by Railsware is a Chrome extension that adds one key function to Airtable for free: the ability to export your tables into Google Sheets automatically.
By specifying a view within Airtable, then copy-and-pasting into Airtable Importer, the tool can be set to pull all the data from the base and import it into a Google Sheet every 1-24 hours on a schedule. This allows duplicates or backups to be made much easier than manual entry every day (or hour!).
