Importing products with CSV - Separate products as product variations

[vivalaskip]

Hi there!

So I have to import this csv file from a partner, but it has over 5000 products. The thing is that I saw that product variations are separate products in the file.

For example: A red t-shirt with the sizes L, XL and S in this file are different rows with almost the same characteristics. The product name column is something like "Product name color size".

I know this might seem impossible (and maybe it is) but if there's a slightly small chance, please help  Also, if someone can make a script or something, I am waiting for a price and timig. Thank you!
