I am trying to migrate all my Magento 1.9 customers (and maybe orders/invoice history as well. Products not needed to transfer) to new Magento 2.3.5 site. I thought I could easily export a.csv file to import to M2, boy was I wrong. I need to find the easiest way to so. Hopefully I don't have to purchase an extension for this.
Any guidance would be appreciated.
