This project allows you to convert the Saved Places.json file that you get from downloading data from the "Your data in Maps" screen in Google Maps. Both GPX and KMZ options are available.
The bookmark name will be set to the name property if available, otherwise to the address, and if neither is available, to the GeoJSON coordinates.
Other metadata fields in the GeoJSON properties such as address, date, and google_maps_url are stored in the export description field, with labels bolded and line breaks.
Note
For converting CSV saved places exports from Google Takeout, there is a Python script available that will require you to generate a Google API key.

This project uses the tokml library from Mapbox, and the togpx library from tyrasd.
This project began as a way to convert Google Maps saved places to Organic Maps. Since CoMaps is a fork of Organic Maps, it can still be used for that purpose. However, due to governance concerns with Organic Maps, the project transitioned to explicitly supporting CoMaps instead.
