Woocommerce Add Functionality to Plugin that exports orders

I am using the "Woocommerce quick export" plugin that exports from Woocommerce all orders and details about the orders. The export is in the form of a csv file. The plugin does not export the variations for each product. I want a small modification of the plugin, so that next to each product, its variation is extracted as well. I will provide the plugin. I have also a second plugin "Simply Order Export", that exports variations (although its other functionality is not useful to me). I can give you the second plugin, if you need it, so as to see how the variations are extracted. In the attached excel file, you can see two sheets. The first sheet is the extracted orders from first plugin and the second sheet is the extracted orders from the second plugin. You will deliver the modification to the plugin. All modifications should be documented.
