google2osmand.js

// Convert Google Maps Locations export to GPX-Data for OSMAnd i.e.
// (build 202006241545)
//
// Howto
// 1. You need a Javascript runtime like Node.js (https://nodejs.org/en/)
// 2. Copy the script into the same directory as your downloaded JSON-File
// 3. Change the "filename" in the script to your JSON-filename
// 4. Run the script on a commandline like "node google2osmand.js"
// 5. Copy/Paste the printed text into a new file which must be called "favourites.gpx"
// 6. Force OsmAnd-App on your mobil to stop. 
// 7. Copy the file to your OsmAnd directory on your mobil /storage/emulated/0/Android/data/net.osmand/files (overwrite)
// 8. Run OsmAnd again and then you should have a new directory of locations called "Google Import"
//
//
