Exporting Sessions as GPX, KML, or CSV

Your detecting data isn't locked inside the app. You can export any session in four different formats depending on what you want to do with it — view tracks in Google Earth, import them into a Garmin, analyse finds in a spreadsheet, or share with a detecting partner.

The Four Formats

SweepTrack JSON — the full-fidelity format. Includes everything: GPS track, finds with all metadata, timestamps, session stats, detector settings. Use this for backups or transferring data between devices running the app.

GPX (GPS Exchange Format) — the universal GPS format. Your track appears as a sequence of waypoints with timestamps. Find locations are saved as named waypoints. Works with Google Earth, Garmin BaseCamp, GPS Visualizer, and almost every mapping tool. This is the format to use if you want to view your track on a computer.

KML (Keyhole Markup Language) — Google Earth's native format. Similar to GPX but with styling information. Your track renders as a coloured line and finds appear as labelled pins. Open the file directly in Google Earth for a 3D flyover of your session.

CSV (Comma-Separated Values) — a flat spreadsheet of your track points and finds. Each row is a data point with latitude, longitude, timestamp, and any find data. Open in Excel, Google Sheets, or any spreadsheet tool. Good for analysing patterns, calculating statistics, or creating custom charts.
