'How operating 32Bit Excel from 64bit EXE
I was able to operate 32bit Excel using Microsoft.Office.Interop.Excel from an application built on x64. I often see that it has to be a 32-bit EXE, but no problem?
Is PIA doing the conversion for us?
windows 10 20H2, .net framerowk ver 4.6.2, Microsoft.Office.Interop.Excel ver 15.0.0.0

No conversion necessary - all Office apps (Excel included) are exposed as out-of-proc COM servers, so the bitness does not have to match: you can access 32 bit Excel from a 64 bit process.
Both 32 and 64 bit versions of Office apps expose the same type library (whcih the interop dll wraps), it is not bitness specific.
