“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.”
HubSpot contact imports get stuck between MAP and Details steps due to server-side validation processes that don’t communicate results back to the UI, browser compatibility issues with large datasets, JavaScript errors, and data formatting conflicts that trigger silent validation failures.
Here’s how to eliminate this specific bottleneck by using a completely different import architecture that bypasses the browser-based wizard entirely.
Eliminate the MAP-to-Details transition with alternative architecture
Coefficienteliminates this specific bottleneck by providing a completely different import architecture. You get direct API integration that bypasses the browser-based wizard entirely, a streamlined process with no multi-step wizard navigation that can break between stages, stable data processing with server-side processing without browser memory constraints, and transparent progress with real-time feedback instead of silent processing stages.
How to make it work
Step 1. Format your contact data in a spreadsheet environment.
HubSpot’sPrepare your contact information in Google Sheets or Excel Online with consistent formatting for dates, phone numbers, and email addresses. This eliminates data formatting conflicts that cause the MAP-to-Details transition to fail innative wizard.

Step 4. Track import progress with detailed status updates.
Monitor your contact import with real-time progress tracking that shows exactly what’s happening throughout the process. You’ll see specific feedback instead of the silent processing that causes HubSpot’s wizard to appear stuck.
Step 5. Handle large contact lists without UI limitations.
Process large datasets through Coefficient’s server-side infrastructure without the browser memory constraints that cause the MAP-to-Details transition to fail in HubSpot’s interface.
