export bulk data - PHP laravel

I m working on a platform and i’m stuck with few issues, please help me out.

I have built a Laravel application(Kind of ecommerce), where users will log in to our store and selects the products they want to sell in their platform(Shopify, Magento, Zencart etc.) add them to their catalog/cart. the users can add up to 15-20K products at a time to sell in their platform.

In their catalog, they have an option o export these product's details in a csv file, but it's taking to much load and end with crashing the browser. is there any way to tackle this issue? instead of loading the data over browser, can we anyhow create the CSV file in the backend of the servers and once its ready we can link it up?

Thank you all!
