Help! need to sell unique downloable files in woocommerce

Hello beautiful people, I have a question for you and I hope to explain myself well for you to understand me as it is a bit complicated to explain, and my english doesn’t help.

I have an online store with wordpress and WooCommerce installed… I need to sell downloadable products (about 100 .doc files with a unique code inside for my clients)

The problem I have is that I need to have one product to sell those .doc.
When my client buy the product, he has to receive a link to download a .doc with a unique code, and that another customer receives a different .doc with a different code and so on until all 100 .doc files I have created run out of stock.

Is this possible to do these in WooCommerce? or perhaps do you know of a plugin to help me do it? or the only option is to hire someone to write a code for me?

The only solution so far that I can think, is for example, create 100 products fully equal in the description, photos, etc … and that each of those 100 products have a Word document with a different code each.

The problem with this solution is that my clients can get confused a lot to see in my store 100 products totally equal and with the same price ….. I hope you have understood me the problem I have.

Any help is very welcome.
