Why convert EXP to SEW?
EXP is the Melco Expanded format, read by Bernina home machines and Melco commercial embroidery machines. 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
EXP files carry no thread-colour information (the format stores raw stitch data with no thread-colour table), so SewFlow assigns a preview palette to each colour block. The stitch sequence and colour stops stay exactly as digitized — check every block in the free preview before downloading.

Frequently asked questions
Will my design stitch out the same after converting EXP 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 EXP 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.
What happens to thread colours when converting EXP to SEW?
EXP files carry no thread-colour information (the format stores raw stitch data with no thread-colour table), so SewFlow assigns a preview palette to each colour block. The stitch sequence and colour stops stay exactly as digitized — check every block in the free preview before downloading.
