Hmmm, Google keep now allows you to export individual notes to Evernote and other apps (https://www.thetechminute.com/export-google-keep-notes-to-evernote/). But, that is a time-consuming task as one can't send all the notes at once. But, why does Evernote has Import from OneNote option but not Google Keep? Does it have anything to do with the unavailability of Google Keep Desktop client?
