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.

Step 3. Preview and test your data export.

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.
