This is one of the most frustrating HubSpot CSV import bugs. When semicolons separate multiple checkbox values within a cell, HubSpot’s parser incorrectly interprets them as column delimiters, breaking the entire import structure.

Here’s how to eliminate this parsing error completely by using direct API integration instead of CSV files.

Bypass CSV parsing entirely using Coefficient

Coefficientcompletely eliminates this parsing error by using direct API integration instead of CSV files. You can keep your data in Google Sheets or Excel with natural formatting and use any delimiter you prefer – Coefficient handles the conversion automatically.

How to make it work

Step 1. Keep your data in your preferred spreadsheet format.

Use commas, semicolons, or any delimiter you prefer in cells. For example, your spreadsheet cell can contain “Option A; Option B; Option C” without any formatting concerns.

Step 2. Configure an export to HubSpot through Coefficient’s interface.

HubSpotHubSpotConnect your spreadsheet toandusing Coefficient. The tool automatically converts your preferred format to HubSpot’s required structure: [“Option A”, “Option B”, “Option C”].

Step 3. Send properly formatted data directly to HubSpot’s API.

Coefficient bypasses CSV parsing entirely, sending data directly through HubSpot’s API. No CSV file generation means no delimiter conflicts or parsing errors.

Step 4. Schedule regular syncs and use formulas for dynamic selections.

Set up automated syncs to keep checkbox values updated and use spreadsheet formulas to dynamically build checkbox selections. Maintain your spreadsheet as the source of truth while avoiding all CSV-related formatting issues.

Never deal with CSV delimiter conflicts again

HubSpot’snative Excel import often provides limited visibility into contact matching failures until after import completion. When contacts don’t match existing records, you typically get cryptic error messages without clear guidance on which specific records failed or why.

Here’s how to proactively identify and resolve contact matching issues before any data touches HubSpot.

Prevent contact matching errors with proactive validation using Coefficient

CoefficientHubSpotprovides superior error handling by letting you identify and resolve contact matching issues in the spreadsheet environment before executing anyoperations. This prevents the reactive cleanup typically required after failed imports.

How to make it work

Step 1. Import existing HubSpot contacts for reference validation.

Pull all your HubSpot contacts with Contact IDs, email addresses, and any other identifiers you’ll use for matching. This creates a complete reference database for validation.

Step 2. Create match verification formulas in Google Sheets.

Use VLOOKUP or INDEX/MATCH to identify which contacts in your Excel data have existing HubSpot records: =IF(ISERROR(VLOOKUP(B2,HubSpot_Contacts!B:A,1,FALSE)),”NEW”,”EXISTING”). This flags each contact as new or existing before any import attempts.

Step 3. Build validation columns for common error sources.

Create columns that flag potential issues: invalid email formats with =IF(ISERROR(FIND(“@”,C2)),”Invalid Email”,”Valid”), missing required fields with =IF(D2=””,”Missing Data”,”Complete”), and duplicate entries within your import data.

Step 4. Separate matched and unmatched contacts into different operations.

Create separate datasets for contacts that matched existing HubSpot records (for UPDATE operations) and new contacts (for INSERT operations). This prevents the mixed-operation errors that cause many import failures.

Step 5. Execute staged processing with error tracking.

Process matched and unmatched contacts in separate Coefficient operations. This lets you resolve matching issues for one group without affecting successful updates for the other group.

Step 6. Create error resolution workflows.

For contacts that don’t match existing records, use spreadsheet formulas to suggest potential matches based on similar email domains or names, making manual review more efficient.

HubSpot’snative Excel import struggles with complex retroactive purchase data because it can’t handle multiple product purchases per contact or properly map to custom deal properties. The standard import tool often fails when dealing with historical purchase data that needs to link to existing contact and deal records.

Here’s how to successfully map and import retroactive product purchase data with proper field mapping and association management.

Handle complex purchase data mapping using Coefficient

CoefficientHubSpot’sovercomeslimitations by providing flexible field mapping for custom properties and the ability to manage complex data relationships. You can validate and structure your purchase data in spreadsheets before pushing clean, properly mapped data to HubSpot.

How to make it work

Step 1. Structure your purchase data with proper field mapping.

Organize your Excel data with columns for purchase date, product name, quantity, value, and contact identifiers. Use Google Sheets formulas to ensure purchase dates are properly formatted (YYYY-MM-DD) and product values are calculated correctly.

Step 2. Create custom properties for purchase history in HubSpot.

Set up custom contact properties for purchase history data like “Last Purchase Date,” “Total Purchase Value,” or “Product Categories Purchased.” Make note of the internal property names for mapping.

Step 3. Import existing contacts to ensure proper associations.

Pull your current HubSpot contacts into Google Sheets to create a reference for contact matching. This prevents creating duplicate contacts when adding purchase history.

Step 4. Map purchase data to contact custom properties.

Use Coefficient’s field mapping to connect your Excel columns to HubSpot custom properties. The system handles data type validation and ensures purchase history maps to the correct contact records.

Step 5. Create associated deal records for individual purchases.

For detailed purchase tracking, use Coefficient’s association management to create deal records for each purchase and link them to the appropriate contacts. This maintains proper CRM relationship structure.

Step 6. Execute batch updates without file size restrictions.

Process your purchase data in batches using Coefficient’s support for large datasets (50,000+ rows). This avoids the file size limitations that cause HubSpot’s native import to fail with extensive historical data.

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.

This error occurs when HubSpot’s CSV parser catastrophically misreads the file structure, typically because delimiter conflicts cause it to interpret the entire row as a single field. This is especially common with multiple checkbox data where internal delimiters conflict with CSV column separators.

Here’s how to eliminate this parsing error entirely and get clear visibility into how your data maps to HubSpot fields.

Eliminate CSV parsing errors with direct API integration using Coefficient

Coefficientbypasses this parsing error entirely by avoiding CSV format. The direct API connection means no CSV file generation, so your spreadsheet structure is preserved exactly as displayed with no delimiter conflicts possible.

How to make it work

Step 1. Import your problematic data into your spreadsheet.

Take the data that’s causing CSV parsing issues and organize it in Google Sheets or Excel. Verify the data displays correctly in separate columns as you intended.

Step 2. Connect Coefficient to HubSpot and map fields visually.

HubSpotHubSpotUse Coefficient’s interface to connect toand. Map your spreadsheet columns to HubSpot fields using the visual mapping interface, which shows exactly how your data will be interpreted.

Step 3. Preview and test your data export.

Use Coefficient’s preview feature to see exactly what data will be sent to HubSpot before the actual export. Test with small batches before running full imports to ensure everything maps correctly.

Step 4. Export data directly with clear error reporting.

Send data directly through the API with no CSV parsing involved. If issues occur, Coefficient provides clear error messages that specify exact field and row problems instead of ambiguous “all columns as one field” errors.
