What version of Excel was used?
Tip:
Since an XML-based file format has been used since Microsoft Office 2007, you have another option here:
1. Take an XLSX (or XLSM) file and change the file extension to .zip.
2. Then open this zip archive and open the app.xml file in the "docProps" folder.
4. In this you will find the entry "AppVersion".
In the inserted file it would be: officeDocument / 2006 / extended-properties
The whole thing can certainly be done programmatically - but the source code should be a little longer, so not really easy either.
In the inserted Excel file you will find a small VBA code to recognize the Excel version. Is only up to Excel 2019, not fully tested (as I said, on the fast :), but it works for my Excel 2016.
File formats that are supported in Excel
Note: Whenever you save a file in another file format, some of its formatting, data, and features might not be transferred.

Hope I was able to help you with this tip / information / link.
