emb to art conversion is actually export between two embroidery design files, from EMB format used in Orchida/Wilcom software to a format specific in Bernina Artista machines.
Not every embroidery design tool might support both of these formats, so a direct conversion can be a little problematic sometimes. But you can always use SVG vector format as exchange medium to transfer the vector data between different software/machines.
