Requires a Node.js-compatible runtime.

node . Timeline.json

Extracted data

Note

Updated: March 2026

Google changes their output annoyingly often. Please open an issue if the script is not compatible with the current export format.

• semanticSegments[].timelinePath[].point
  • ./time
• semanticSegments[].visit.topCandidate.placeLocation.latLng
  • (if ../../probability > 0.5)
  • (and ../probability > 0.25)
  • ../../../startTime
  • ../../../endTime
• semanticSegments[].activity.start.latLng
  • ../../startTime
• semanticSegments[].activity.end.latLng
  • ../../endTime
• semanticSegments[].activity.parking.location.latLng
  • ../startTime
• rawSignals[].position.LatLng
  • ./timestamp
  • ./accuracyMeters? (not supported as CSV column)
  • ./altitudeMeters?
  • ./speedMetersPerSecond?

Example

This script outputs a CSV file:

GPSDateTime,GPSLatitude,GPSLongitude,GPSAltitude,GPSSpeed (m/s)
2026:02:09 16:04:53+00:00,52.6972529,-1.6781693,107.19999,1.059999
