Wonder how extensively VBA is used in today's Excel. I know that macros are considered dangerous but would love to know if there are exceptions for that rule.
On the other hand I wonder why aren't they run in such a sandbox where the most destructive action they can do is to wipe the sheets.
You need a genuine licensed excel to run the file and prepare returns. Thankfully you can file same returns online on the portal for free so they get a safe pass that way.
Edit: it's actually 50klocs since the pyOpenVBA dependency is from the same author and has been made the week-end before.
