A disabled “Next” button despite mapped columns typically indicates hidden validation errors, required field issues, or data format problems that HubSpot’s interface doesn’t clearly communicate to users.

Here’s how to get transparent validation feedback and successfully import your Excel contact data without guessing what’s wrong.

Get clear validation feedback with Coefficient

HubSpotCoefficientUnlike’s wizard which may disable the Next button without explanation,provides explicit validation results in your spreadsheet. You’ll see exactly which cells contain invalid data, why they’re invalid, and how to fix them before attempting the import.

The system identifies common hidden validation issues like malformed email addresses, date format conflicts, missing required field data, character limit violations, and duplicate email detection that would silently block HubSpot’s native import process.

How to make it work

Step 1. Connect your Excel file to Coefficient.

Install Coefficient and connect to your Excel file containing the contact data. The system will analyze your data against HubSpot’s validation requirements before attempting any import.

Step 2. Run pre-validation checks.

Use Coefficient’s validation features to check data quality before attempting the HubSpot import. You’ll get detailed feedback about email format issues, date formats that don’t match HubSpot’s requirements, and text fields exceeding character limits.

Step 3. Fix identified validation errors.

Review the validation results and correct any identified issues directly in your Excel file. The system shows specific errors about required field problems and property limit violations, so you know exactly what to fix.

Step 4. Execute the successful import.

Once validation passes, use Coefficient’s export-to-HubSpot functionality to import your contacts. The system imports all valid records while clearly identifying any that still need correction, using batch processing to isolate problem records.
