This came up in a support forum post: Importing Data into an Existing Table
Airtable would be able to address more of my clients’ CRM use cases if it had the ability to import data into existing tables. Lead management is an example. Over time a company gets batches of leads in a spreadsheet that they need to be able to import into a Leads app. Duplication detection and record updates are key features that ensure the lead qualification process ends up being as efficient as possible.
Copy and paste is a workable solution but there are a bunch of other reasons why Airtable needs the ability to import from a spreadsheet into an existing table. This additional import functionality would need to be able to set up data keys, driving an update for any existing records with the same key and creating new records for ones that don’t already exist in the table.
