HubSpot CSV import
Fix HubSpot CSV import errors before mapping contacts
Clean up structural CSV issues that commonly block HubSpot imports, including duplicate headers, inconsistent rows, and formatting problems.
What this problem usually means
HubSpot imports rely on clean columns and predictable mapping. Even when HubSpot accepts .csv, .xlsx, and .xls files, the import still depends on usable headers and consistent row structure. ImportFix helps clean the file before you go through HubSpot's mapping workflow.
Why it happens
- The file was exported from another CRM or spreadsheet and no longer has clean import-ready structure.
- Duplicate headers or blank columns make HubSpot mapping harder to review.
- Some rows are malformed, leaving contacts with missing or shifted values.
What ImportFix checks
- Duplicate headers, empty rows, and empty columns
- Row-length consistency against the expected header shape
- Whitespace, duplicate rows, and delimiter problems
- Previewable repairs before the file reaches HubSpot import mapping
Common repairs
Rename repeated headers for safer field mapping
Normalize row lengths and clean blank rows
Trim extra whitespace around names, emails, and other values
Export a cleaner CSV for the next HubSpot import attempt
When to review manually
Structural cleanup will not choose HubSpot properties for you. After repairing the file, review the column mapping carefully in HubSpot and confirm a few records before importing at scale.
