Hi,
When a column with the same information exists already in HikaShop, you have to change the column name to match with the one in HikaShop.
For the information which doesn't have an equivalent in HikaShop, you can create a custom product field with the same column name and the import will import the data in the custom field.
The best is to create one or two products to have them display like you want. Then, use the "export" button of the products listing to get a CSV with these products and check the data for each column in the CSV from HikaShop so that you know what column name you want to change in your CSV to match with the ones in HikaShop.
If you want to automate the process and not rename the columns, you can use the HikaShop product cron update plugin to import the CSV regularily with a columns conversion system:

That way, you can avoid renaming the columns each time in the CSV, you just have to upload the new CSV on top of the old one used by the import plugin and wait for it to do the import.
