csv to dxf conversion is sometimes used to translate vectors (coordinates) saved in CSV (comma separate value) files to standard DXF format. This is often used for embroidery, quilts and similar design purposes, but sometimes even for technical drawings.
The software options depend on what kind of content and to which format you need to convert it, it's hard to give specific answer simply because of too many possible variants.
