There are many tools in Magento which allow you to view or generate and download different reports. So, we can conclude that Magento system has integrated tools for CSV and XML files generation. It might help in the situation when you need to generate a report for some feed or just export a list of structured data. We would like to demonstrate the small example that adds an ability to generate and download CSV files.
Let’s assume that you have already created your custom extension and wish to add a CSV export functionality. If it’s not the case and you can’t guess how to create an extension, then you can always find the light in our previous articles, for example this one. We called our extension Atwix_Tweaks so in the code examples below we will use this title.
