Jack, Jesus, If we were talking about data formatting only, without additional benefit of actually embedding the formulas, I would advise against .ods due to its sheer complexity – which Jack already mentioned. HTML is flexible enough to support all our regular 'static' reports needs, and the generated report can be exported to .PDF of .ODS easily. Moreover, Skrooge already supports adding additional HTML reports via store.kde.org and I would look into supporting their API to make the reports universally compatible: https://store.kde.org/p/1206640/
As for embedding the formulas, that would definitely be a nice to have but potentially also a nightmare to manage in C++. Python, on the other hand, would be absolutely perfect for this, due to the number of libraries readily available, e.g. http://docs.pyexcel.org/en/latest/ I recently suggested adding support for Python plugins as one of the milestones for KMM: https://invent.kde.org/office/kmymoney/-/milestones/4 . It actually wouldn't be that difficult to implement, given that Krita already did it and most of the work would be literally just copy-n-pasting. -- Regards, Dawid
