Why convert XXX to SEW?
XXX is the Singer/Compucon format, read by Singer Futura series machines and Compucon EOS software. Convert to SEW when your older Janome or Elna model reads SEW. SewFlow re-encodes your existing stitches for the new format — it never re-digitizes, so the design sews out identically.
What happens to thread colours
XXX and SEW both store thread colours, so your colour sequence transfers automatically — SewFlow re-encodes each thread into Janome palette indices. The XXX file keeps an RGB thread-colour table alongside the stitch data; the converted SEW file stores thread colours as Janome palette indices, like JEF.

Frequently asked questions
Will my design stitch out the same after converting XXX to SEW?
Yes. SewFlow re-encodes the same stitches rather than re-digitizing: stitch paths, jump and trim commands, and colour stops are preserved exactly, so the SEW file sews out identically to the original XXX design.
Which machines read SEW files?
SEW (Janome SEW format) is read by older Janome and Elna machines (Memory Craft 8000/9000 era) and some Bernina models. Copy the file to the memory card or USB medium your machine reads.
