Step 3. Set up the export with automatic field mapping.

Use Coefficient’s “Export to HubSpot” feature and select the INSERT action to create new contact records. The system automatically suggests field mappings based on your column headers. Map address fields to HubSpot’s specific address properties like Street, City, State, and Postal Code.

Step 4. Test and schedule ongoing exports.

Run a test export with a small subset of your customer data to verify field mapping and data formatting. Once confirmed, set up scheduled exports to automatically sync new customers as you update your spreadsheet.
