Imagine you’re importing a data file using HubSpot’s native import tool. In the preview window, you receive an error notification with the error code, “Could not parse date.” What does this error indicate?

This error occurs because HubSpot's system attempts to interpret a date column using a specific sequence (such as MM/DD/YYYY or DD/MM/YYYY), but encounters data rows that violate those structural rules. For example, if the import settings are configured to read the file as MM/DD/YYYY, but a spreadsheet row contains the date written as 28/05/2026, HubSpot will flag a parsing failure because it recognizes "28" as an impossible 28th month of the year. To resolve this, you must ensure that your spreadsheet data strictly aligns with the formatting option designated during the initial steps of the import wizard.
