Microsoft interop supported files

Question

I searched a lot but I was unable to find what excel files are supported by Microsoft Interop. I want to make a full 97-2013 excel support on a project and I don't know if Inrerop can support old files. Can anyone to help me ? Thanks!

You might be asking the wrong question (which is probably why you did not find this information online).

Interop is just an interface layer to the installed version of Office. If the Excel version installed supports the files you are interested in, it does so as well when remote-controlled through interop. If it doesn't, interop won't add this functionality.
