I would like to create a module ,where i can read and excel file & add
products & categories from the code. I am new to magento so
i don't now how to get started. Setting up a new module is no problem. There a very useful tutorials on the web.
Reading my excel file is not the problem, but how can ,i add products & categories. Should ,i work with the API or directly with product entities ?
Is there any guide on how to add categories & products via my module code?
