Import2 can’t maintain deal-activity associations because it processes single objects rather than complex relationships between multiple HubSpot records.

Here’s why this happens and how to import deals with their associated activities intact.

Import deals with activity associations using Coefficient

Coefficienthandles multi-object relationships that CSV-based tools like Import2 simply can’t manage. Instead of losing activity associations during import, you maintain complete deal context with all related activities, contacts, and companies.

HubSpotThe key difference is Coefficient’s association management capabilities, which let you import deals while preserving their relationships to otherobjects.

How to make it work

Step 1. Set up multi-object import with association mapping.

Connect your Excel data to Coefficient and select deals as your primary object. Then configure which associated objects (activities, contacts, companies) should be included in the import process.

Step 2. Choose your association display format.

Select how you want associated activities to appear: Primary Association shows the main activity, Comma Separated lists multiple activities in one cell, or Row Expanded creates separate rows for each activity association.

Step 3. Map activity relationships using unique identifiers.

Use HubSpot Object IDs or other unique identifiers in your Excel data to maintain proper associations between deals and activities. Coefficient validates these relationships before importing.

Step 4. Execute the import with real-time association tracking.

Run the import while monitoring association status. Coefficient provides feedback on which relationships were successfully created and flags any association issues for review.
