Which GPS Format Should I Use?

Format Best For Pros Watch Outs
GPX Universal tracks and waypoints Simple XML and broad support Can get large with many points
KML Google Earth and route previews Good for styled viewing and map sharing Heavier XML, styling varies by app
TCX Fitness workouts Useful for laps and sensor-rich workouts App support can vary compared to GPX
FIT Garmin and modern wearables Efficient binary format with more sensor detail Needs decoding before manual editing

Best Practices

Use-Case Playbooks

Fitness & Coaching: merge weekly FIT or TCX files, export to CSV, then analyze pace, laps, and heart rate trends.

Field Operations: convert logs to XLSX, filter by time window, then export a GPX route for handoff.

Delivery & Service: build KML route previews for Google Earth and team reviews.

Research & GIS: export GPX, clean it in a spreadsheet, then import into GIS software.

FAQs & Troubleshooting

Do my files upload anywhere? No. Everything runs locally in your browser.

My FIT file won’t parse. Some devices export different variants. Re-export from the vendor app and try again.

Data looks shifted or empty. Check time zones and make sure lat/lon columns are numeric.

Very large files feel slow. Close heavy tabs and consider splitting or downsampling routes.
