“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’s CSV import has column count limitations and requires headers for every column. This causes “too many columns” errors when your CSV contains more fields than the validator can process.
Here’s how to handle large CSV files with unlimited columns and transform data for optimal HubSpot integration.
Import large CSV files without column limits using Coefficient
Coefficient provides superior CSV handling by separating data ingestion from HubSpot integration. Your CSV can have any structure or column count while Coefficient transforms that data into HubSpot-compatible contact records.
How to make it work
Step 1. Import large CSV files without restrictions.
Use Coefficient to import CSV files with unlimited columns into your spreadsheet environment. This eliminates HubSpot’s column count constraints while preserving all your contact data for processing.
Step 2. Select specific fields for HubSpot contact creation.
Choose exactly which columns from your CSV should become HubSpot contact fields. This selective approach eliminates the “too many columns” constraint by focusing only on relevant contact information.
Step 3. Transform CSV data for optimal HubSpot structure.
Use spreadsheet functions to combine, split, or reorganize CSV data before exporting to HubSpot. This optimizes your data for HubSpot’s field structure without the limitations of the native CSV import validator.
Step 4. Set up automated CSV processing workflows.
Schedule regular imports from large CSV files with automatic field selection and data transformation. This creates a sustainable process for handling complex CSV data without column restrictions.
Handle CSV complexity without HubSpot limitations
This approach treats CSV files as flexible data sources rather than rigid import formats. Column count becomes irrelevant when you can selectively process and export only the contact data you need. Start with Coefficient to eliminate CSV import restrictions.
