I think I heard that the 830 also reads EXP format and that is readily available in the conversion options.
Wow, was surprised to see that my Buzz tools buzzxplore doesn't convert to ART format. Thanks for asking the question as now I will look closer at software available for multi format conversion.
Just Bernina software converts to ART.
None of the others do it.
Pulse Ambassador will convert to the Pes files that are used by Bernina and Babylock machines.
You need the Bernina software, no other programme can convert TO art, though most can concert FROM it.
Try "Wilcom True Sizer" that is what I use to convert to JEF. It has many other formats to convert to.
