“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.”
An infinite loop at the mapping stage occurs when HubSpot’s import wizard encounters validation errors that cause it to continuously revert to the mapping screen without progressing, creating a frustrating cycle where you can’t complete your import.
Here’s how to break this loop and get your contact data imported successfully using a more reliable method.
Break the loop with an alternative import method using Coefficient
CoefficientHubSpotcompletely bypasses’s problematic import wizard, eliminating the infinite loop scenario entirely. Instead of relying on the browser-based interface, Coefficient uses direct API connections that process imports reliably without getting stuck in validation loops.
HubSpotThe infinite loop usually stems from hidden required fields, data format mismatches, property limit conflicts, or association errors that aren’t properly surfaced. Coefficient’s comprehensive pre-validation identifies these issues upfront, and its incremental processing imports valid records while isolating problematic ones without session dependencies that contribute toinfinite loops.
How to make it work
Step 1. Connect your Excel or Google Sheets data to Coefficient.
Install Coefficient and establish a connection to your spreadsheet containing the contact information. This creates a direct pathway that doesn’t depend on HubSpot’s browser-based wizard interface.
Step 2. Use the Export to HubSpot feature.
Select the “Export to HubSpot” option and choose the Contacts object. This linear process prevents the circular validation loops that plague HubSpot’s native wizard.
Step 3. Review comprehensive validation results.
Run Coefficient’s validation check to see detailed error reporting that shows exactly which rows and fields have issues instead of generic mapping errors. Fix any identified problems with data formats, required fields, or property limits.
Step 4. Execute the import successfully.
Once validation issues are resolved, run the import process. Coefficient’s incremental processing handles large datasets without the browser-related issues that contribute to infinite loops, and provides detailed error logs for any remaining issues.
