Please note, the list of all fields you can map is far greater, and can be found in the mappings step during your import.
If you have any questions on a particular mapping, feel free to chat with us and we can walk you through it!
1. Industry is an example of a picklist field. You must have the same list of options setup in the field as those that exist in your CSV file in order for the mapping to work. The same logic applies for any other picklist fields you wish to map on the Company record.
2. Owner is a lookup mapping, which means that it will look at the users that exist in your HubSpot account. You must have the owner setup prior, and have their identifying information in your CSV file (like email address, or name) which matches what is in HubSpot, in order for the mapping to work.
3. Hubspot assigns the create date when you import the record. This cannot be changed, and is not included in the list of available mappings.
