Converting One Note to Markdown

This is an example of how to convert notes from OneNote into Markdown to use in other, less annoying Note applications. I am using PowerShell on Windows here, but other shell/scripting environments would work as well. If you want separate .md files, you'll need to export your OneNote pages separately. Exporting a section, or a selection of pages creates a single .docx file.

Download and install Pandoc
Export each of your note pages to a .docx (Word) format using OneNote export from the File menu
Gather all of these .docx files into a directory
Open directory in File Explorer
Open Powershell from the File Explorer using File -> Open Windows Powersell
Run the following command:

ForEach ($result in Get-ChildItem | select Name, BaseName) { pandoc.exe -f docx -t markdown_strict -i $result.Name -o "$($result.BaseName).md" --wrap=none --atx-headers }

markdown-strict is the type of Markdown. Other variants exist in the Pandoc documentation
--wrap=none ensures that text in the new .md files doesn't get wrapped to new lines after 80 characters
--atx-headers makes headers in the new .md files appear as # h1, ## h2 and so on
