I have a task to import products from m1 to m2.
I having the CSV file with products(from Magento 1 export) at the moment. When I try to "Check Data" on the import page - is always loading.
How can I import products from m1 to m2 via CSV file or another approach except for data-migration-tool?
P.S magento 1 - 1.9.3.1, magento 2 - 2.3.0
