Over the last while I've been pleasantly surprised at the extent to which I can use OpenOffice on Linux to work with Word and Excel data. I've even created a few Word/Excel files and send to others without them being any the wiser that Word/Excel did not feature in there creation.
Visio however, is a tougher nut to crack. In IT Consulting the chances of not encountering Visio files is vanishingly small in my experience.
Everywhere I've looked suggests that Visio file format are just plain opaque and no tools out there can read/write 'em.
Can this be true? Say it isn't so.
