Convert Synology Note Station to Microsoft OneNote -- 2

I am seeking a simple Windows-based (can be command line run) utility/script to batch convert 1,000+ notes that are held in a Synology Note Station .NSX export format (which is a compressed file) into something that can be read by Microsoft OneNote. Based on my internet research there appears to be a couple of options: 1) Convert NSX to Evernote format, then run the free Microsoft OneNote import tool 2) Convert NSX to a series of HTML files, then run an existing shareware utility called OneNote Batch 3) Something else I am not thinking of As background, there is an existing utility ([login to view URL]) that can convert NSX files to markdown, but that can't be read by OneNote. I also have posted this question to Synology's forum but have not received a solution ([login to view URL]). Thank you for your consideration and please feel free to reach out with any questions about this job.
