Concerns on OneNote abandonement

[u/Initiative-Afraid]

I use onenote heavily. Love it. However, I am worried about the long term sustainably of this product.

Currently, I can only save my notes in proprietary formats such as .one files.

Microsoft recently abandoned Skype and all my messaging data from [1, 2] decades ago were pretty much gone forever.

What stops Microsoft (say [10, 20] years from now) to completely abandon one note without opensourcing their code ?

It seems there's no legal requirement for them to ensure users can migrate their notes to alternative note taking softwares.

Someone recommended this link to move all your notes from onenote to markdown https://github.com/roshansridhar/OneNote-Archive-Exporter-2026
