Schöne sache
Vielleicht hat jemand lust diese mit adodb und DispHelper zu realisieren.
Dann läuft es auch, ohne das Excel installiert wurde.

Es wird problematisch, da ADODB nicht über die Befehlreferenz von Excel verfügt. Daher die Möglichkeit z. B. SetColor, PageSetup u.s.w. fehlen. Datenzugriff ist jedoch möglich, aber ziemlich eingeschränkt.
Ich habe die Code von Kiffi etwas modifiziert:
