gotoextr

Small and durty program to extract GPX data from Google Takeout Location History.

Hence the name: Google Takeout Location History Extractor → gotoextr.

Usage

1. Download your location history from Google Takeout as zip archive.
2. Run gotoextr with the downloaded archive as argument. For example to extract data for January 1, 2023 run:

gotoextr -s 2023-01-01 takeout-20230501T000000Z-001.zip

The output will be written to the file history_2023-01-01.gpx.

You can also manually extract Records.json and use it as parameter. Once extracted this file is quite big (several hundred MB).

Why?

I use my travel history to geotag my photos. I often use a tracking application to record my positions, but occasionally (often?) I forget to launch it. In this case, Google Takout (Location history) helps me by extracting my tracks in GPX format.

Inspiration

This software is strongly inspired by location-history-json-converter 🙏. But since the pyton application is rather slow, I decided to make one in go that is about 10x faster. The original application is also more complete, I only implemented the features I needed.
