HubSpot companies CSV template: fast prep guide

Getting your companies CSV right before import saves time and avoids rejected rows.

Recommended starting columns

• name — required by HubSpot for companies
• domain
• phone
• city
• country

Common mistakes to avoid

• Duplicate headers — causes the mapping step to fail entirely.
• Mixed date formats in the same file — normalize before export.
• Malformed domain values — strip protocols (https://) where not expected.
• Blank name values — every company row needs a name.
