I've tried to install Easy Populate but I need some changes because of my setup. The shop also used Custom_META_Tags_per_Item and therefore there are some product attributes that needs to be added to the Easy Populate script.
The tasks are therefore:
Check Easy Populate installation
Make needed changes
Test and verify that the Easy populate can export data into an excel file and that you can add new product and create them by uploading the file
Additional task: Upgrade to latest version
