How to make an extensive product page (Not Store) in wordpress.

thanks for taking the time to read this, and I hope you can point me in the right direction. So, my employer wants me to make a site (surprise) for a Brand we carry, this brand has very many products, of all different types, and sub-brands. There are something like 6000+ seperate model numbers / products that we wish to have cataloged on the site.

My question is, what would be the best way to automatically generate these items on a page, preferably in a gridded format ( just image, product # and name, no cost / shopping cart functionality ). We have excel files and .csv’s of all the products available, but need to know the best way to upload these, and generate them ( as automatically as possible, as 6000 manual entries would cause me to blow my brains out ).

If there is a plugin, or a few plugins, that would help me accomplish this, please share it with me. ?? I look forward to any reply and guidance. Thanks in advance, you’ve never failed me yet, and I hope that doesn’t change. <3

Sincerely,

Toker.
