For bulk Outlook contact imports, converting XLSX to VCF is usually the cleanest approach. Outlook accepts vCard files, but Excel spreadsheets need proper formatting first.
A good converter should offer:
Bulk conversion without file size limits
Field mapping (Name, Email, Mobile, Company)
Single or separate VCF export options
Duplicate contact removal

Excel to vCard Converter is one option that handles large Excel contact lists and creates Outlook-ready VCF files. It also provides a preview before export, which helps avoid missing fields or incorrect mapping.
This saves a lot of time compared to manual CSV import issues.
