“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.”
HubSpotCustom field mappings betweenand Google Sheets often break when fields are renamed, modified, or when connectors map by display name instead of stable field identifiers.
Here’s how to create persistent field mappings that survive HubSpot schema changes and maintain data integrity across refreshes.
Persistent field mapping with ID-based connections using Coefficient
Coefficientsolves custom field mapping stability by connecting to HubSpot field IDs rather than display names. This means when you rename a custom property in HubSpot, your Google Sheets mapping doesn’t break because the underlying field ID remains the same.
The system preserves column headers and their connections to HubSpot fields, maintains previous column positions during re-imports, and supports all custom property types with proper data type preservation. This creates stable mappings that work reliably over time.
How to make it work
Step 1. Establish baseline mappings with field ID tracking.
Install Coefficient and connect to HubSpot. When selecting fields for import, custom properties appear with clear labels and their data types. Choose your fields and import to establish the baseline mapping. Coefficient automatically maps by field ID, so these connections remain stable even if you rename fields in HubSpot later.
Step 2. Protect and document your mapping structure.
Lock row 1 in your Google Sheet to prevent accidental header changes that could break formulas. Create a reference sheet that documents which HubSpot field corresponds to each column. Use named ranges for your imported data areas so formulas reference stable names instead of cell ranges that might shift.
Step 3. Configure field aliasing for readable column names.
Use Coefficient’s field aliasing feature to rename columns in Google Sheets while maintaining the HubSpot connection. For example, you can display “Lead Score” as the column header while it remains connected to HubSpot’s “hubspot_score” field. This gives you readable headers without breaking the underlying mapping.
Step 4. Handle schema changes gracefully.
When you add new custom fields in HubSpot, they automatically appear in Coefficient’s field selector for future imports. If fields are modified in HubSpot, changes reflect in the next refresh without breaking existing formulas. If source fields are removed, Coefficient shows clear error messages so you can update your imports accordingly.
Step 5. Set up two-way sync validation.
If you’re using Coefficient’s export features to update HubSpot from Google Sheets, the bidirectional mappings work automatically. Custom fields can be updated from Sheets back to HubSpot with validation to ensure data types match before pushing updates. Association fields maintain their relationships during two-way sync.
