The problem this solves
Google moved Maps Timeline on-device only in late 2024 — there's no web view, no Google Takeout export for new data, and older history was deleted unless you backed it up. So your whole location history now sits in a Timeline.json file on your phone with no easy way out.
Most converters are websites that ask you to upload your entire location history to a stranger's server, or desktop Python scripts. Timeline Exporter does the conversion right on the device where the file already lives — nothing is uploaded, ever.
Export to anything that reads GPS tracks
How to convert Timeline.json to GPX on Android
- On your phone: Settings → Location → Location services → Timeline → Export Timeline data. This saves a
Timeline.json. - Open the file in Timeline Exporter (or share it to the app from your files).
- Preview the track on a map and filter by date if you only want part of it.
- Export to GPX, KML, GeoJSON or CSV and open it in any GPS app.
