Hi,
It will take a bit of time to get used to;
The spreadsheet contains details/instructions on the first page.
The second page is where you enter the info ( almost similar to turbolister), it also gives an example and red corner tabs with further instruction when you hover over.
The third page contains the catagori numbers eg if you are selling Antiques : Architectural Antiques : Tiles cat no 4675 you would enter 4675 into second page column B Category id.
etc etc.
