hello @jwelton,
If you navigate to the Hardware asset table - "alm_hardware." Click the list option "hamburger." Select the "import" option.
This will open a new window. SN will give you an option to create an "excel template" with all the columns in the table.
I have attached the template to this. Keep in mind the template I have attached is only OOTB columns. If you have created any custom columns, you will have to do the steps above to get a template that matches your table.
Please mark it as helpful (or) correct if it fixes your issue.
