Hello,
This can be an Excel add-on, with its own icon on Excel's Ribbon. I will need both files (sample tax data file and the e-faktur template file). It will be ready in max 3 days, including all necessary tests.
A few words about me: I'm developing VBA programs for more than 15 years and I'm a VBA and Excel trainer (all levels) for 12+ years. As you can guess, I have created a plethora of VBA programs of almost any kind, for both training purposes and business.
Looking forward to hear from you,
Kind regards,
Chriskerpini
