Specific HubSpot field types consistently break during Excel reimports, causing frustrating upload failures. Date fields, multi-select properties, and association data are the biggest culprits behind import errors after deduplication.
Here’s how to identify and prevent the field-level issues that derail your clean data uploads.
Prevent field formatting disasters with native data handling using Coefficient
CoefficientHubSpotsidesteps the formatting issues that plague traditional CSV imports by maintaining nativefield formatting throughout your deduplication process.
How to make it work
Step 1. Preserve date and datetime field formatting.
HubSpot requires ISO 8601 formatting (YYYY-MM-DDTHH:MM.sssZ) for datetime fields. Excel exports often corrupt timezone information, but Coefficient maintains original HubSpot date formatting automatically. No manual conversion needed.
Step 2. Handle multi-select properties correctly.
Multi-select fields need semicolon-separated values, not commas. Traditional Excel processing converts these to comma separation or corrupts special characters. Coefficient preserves the exact formatting HubSpot expects: “Option 1;Option 2;Option 3”.
Step 3. Maintain object association integrity.
Association data between contacts, companies, and deals gets lost in manual CSV exports. Coefficient’s Association Management feature keeps all object relationships intact during deduplication, preventing the relationship breaks that require manual fixing.
Step 4. Skip calculated and formula properties.
HubSpot’s calculated fields are read-only and cause import failures when included in uploads. Coefficient automatically recognizes and excludes calculated properties from update operations, preventing these validation errors.
Step 5. Preserve enumeration property values.
Dropdown and radio select properties require exact value matching. Excel processing introduces case sensitivity issues and spacing problems. Coefficient maintains original enumeration values without corruption: “Sales Qualified Lead” stays exactly as “Sales Qualified Lead”.
