When HubSpot’s import wizard won’t advance from the mapping step despite correct mappings, you’re likely dealing with hidden data validation errors, session timeouts, or property limit conflicts that aren’t surfaced to users.

How to make it work

Install Coefficient and connect to your Excel or Google Sheets file containing the contact data. The connection works with files stored locally or in cloud storage.

Step 2. Use Coefficient’s HubSpot export function.

Select the HubSpot export option and choose the Contacts object. This bypasses all the problematic wizard stages that cause mapping failures.

Step 3. Configure contact property mapping.

Review the automatic field mapping suggestions and make adjustments as needed. You can apply up to 25 filters to import only clean, validated data and see exactly how your data will map to HubSpot properties before import.

Step 4. Execute the import with real-time error feedback.

Run the import process, which includes detailed error tracking that shows which specific records failed and why. You can import data in smaller batches to identify problematic records or run incremental imports to handle large datasets.
