Why isnt WooCommerce importing my .csv?

im too have a problem with woocommerce importer .
I want to import from csv file with my products but when downloading I can put only 30 products after then I removed first 30 products which could downloading and continue loading and yours importer starts uploading only 4 products.
dont know what to do !

I had trouble importing the products as well. It was 17 and it did not matter at all. I had to register everything manually and I still think it must have spoiled something on my site because there were problems that did not exist before. Such as shortcode of best selling products and identification of new products.

See https://docs.woocommerce.com/document/product-csv-importer-exporter/ and https://github.com/woocommerce/woocommerce/wiki/Product-CSV-Import-Schema

Why do you have ID = 0 in your CSV? If the product doesn’t exist in WooCommerce yet, don’t set an ID. Also be aware of what selecting “merge existing products” does when checked/unchecked.
