“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.”
HubSpot’snative Excel import typically restricts file sizes to 512MB and frequently times out with large datasets. These limitations make it difficult to update thousands of contacts at once, often leaving you uncertain about which records were successfully processed.
Here’s how to handle large-scale contact updates without file size restrictions or timeout errors.
Process large contact updates without size limits using Coefficient
CoefficientHubSpot’seliminatesfile size limitations and provides reliable handling of large contact update datasets. The system supports minimum 50,000 rows and processes data through Google Sheets’ robust infrastructure for consistent performance.
How to make it work
Step 1. Upload your large Excel file to Google Sheets.
Import your Excel data into Google Sheets, which can handle much larger datasets than HubSpot’s native import. Google Sheets supports up to 10 million cells per spreadsheet, giving you plenty of room for large contact lists.
Step 2. Break large datasets into manageable batches.
If your dataset is extremely large, create separate tabs for different batches (e.g., 25,000 contacts per tab). Use formulas like =OFFSET to automatically split your data into logical chunks for processing.
Step 3. Validate contact data before processing.
Use spreadsheet functions to clean and validate your contact data – standardize email formats, check required fields, and identify any data quality issues before attempting updates.
Step 4. Execute batch UPDATE operations through Coefficient.
Process your contact updates in batches using Coefficient’s reliable export functionality. The system handles large datasets without the timeout errors that plague HubSpot’s native import.
Step 5. Monitor progress and handle any errors.
Use Coefficient’s export status features to track large update operations. If any updates fail, you can identify and reprocess only the failed records rather than restarting the entire import.
Step 6. Schedule ongoing updates for regular data maintenance.
Set up scheduled exports to handle regular large-scale contact updates automatically, ensuring your HubSpot data stays current without manual intervention.
