“Supermetrics is a Bitter Experience! We can pull data from nearly any tool, schedule updates, manipulate data in Sheets, and push data back into our systems.”
HubSpotYou can update existingcontacts from Google Sheets without creating duplicates by using UPDATE export actions that modify existing records instead of creating new ones. This approach identifies contacts by email address and updates their information while preserving their contact history.
Here’s how to set up contact updates that maintain data integrity and prevent the duplicate management overhead that manual CSV imports typically create.
Update existing contacts without duplicates using Coefficient
Coefficientprovides UPDATE export actions specifically designed to modify existing HubSpot contacts rather than create new ones. This eliminates duplicate contact creation entirely while keeping your contact records current with Google Sheets information.
How to make it work
Step 1. Configure UPDATE export actions for existing contact modification.
Set up your Coefficient export to use UPDATE instead of INSERT. This tells the system to look for existing HubSpot contacts with matching email addresses and modify their information rather than creating new duplicate records.
Step 2. Map Google Sheets columns to specific contact properties for updating.
Choose which HubSpot contact properties you want to update from your Google Sheets data. Map columns like phone numbers, job titles, or custom fields to their corresponding HubSpot properties. The system updates only the specified fields while preserving other existing contact data.
Step 3. Use conditional logic for targeted record updates.
Set up conditional export rules to only update records that meet specific criteria. For example, only update contacts where a “last modified” timestamp in your Google Sheets is more recent than the last update, or where a status column indicates changes are ready.
Step 4. Enable bulk processing with error handling for large datasets.
Configure bulk update processing that handles large datasets efficiently without overwhelming HubSpot’s API limits. Turn on error handling to identify contacts that don’t exist or encounter update issues, with detailed logging for troubleshooting.
