“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.”
The “MAP to Details” transition failure in HubSpot’s import wizard often stems from validation errors that aren’t properly displayed or browser compatibility issues that prevent the process from advancing.
Here’s how to bypass this problematic workflow stage entirely and get your Excel contact data imported successfully.
Use a direct Excel-to-HubSpot connection with Coefficient
CoefficientHubSpotprovides a more reliable alternative that completely sidesteps the MAP to Details transition point where users commonly experience failures. Instead of relying on’s multi-stage import wizard, you get a direct connection that validates your Excel data before any import attempt.
This approach eliminates browser dependency issues, handles large datasets without timeout problems, and provides detailed error logs when validation issues occur.
How to make it work
Step 1. Install Coefficient and connect your Excel file.
Set up Coefficient in your spreadsheet environment and connect to your Excel file containing the contact data. This works whether your file is stored locally, in OneDrive, or SharePoint.
Step 2. Select the Export to HubSpot option.
Choose “Export to HubSpot” from Coefficient’s menu, then select the Contacts object. This bypasses HubSpot’s problematic import wizard interface entirely.
Step 3. Map your Excel columns to HubSpot contact properties.
Review the automatic mapping suggestions and adjust as needed. Coefficient supports custom contact properties and provides clear field mapping previews so you can see exactly how your data will transfer.
Step 4. Validate and execute the import.
Run real-time validation to catch date format issues, email validation problems, or missing required fields before the import starts. Once validation passes, execute the import or schedule it for automatic execution.
