key to odp conversion is mostly searched by users that have old iWork Keynote presentations (.key) and want to export / convert these to a format useable in Windows, for example .odp format from OpenOffice.
Some sources claim that certain versions of LibreOffice Impress actually do or did support some versions of iWork Keynote presentations, but we could not reliably verify this claim.
In any case, we do not know about any converter for this, so the only remaining option would be to use some exchange format, but you will stil require access to software that can open / export .key files.
