This is how you can get it.
1. Get the file content in to a data item using Calc stage with LoadFile("<FilePath>") passing the file path in to the function.
2. Use Utility String vbo and Split Lines action to get them in to a collection with two rows
3. Use Loop stage on each row and use 'Split Text' action passing comma (,) as delimiter to split the row content in to a collection.
Disadvantage is that, you will get a collection for each row and have to use 'Merge' action from Collections Manipulations VBO if you wish to end up with single collection at the end. Note: if the same column names exist in collections, 'Merge' will return an error. You have to change the Field names before Merging.
Hope this helps!
