Load, map, analyze, and export route data privately in your browser with cleaner preview, stats, splits, and conversion tools.
Preview tracks on a map, compute distance and pace, build splits by km or mile, remap spreadsheet columns, and export back to GPX, KML, TCX, CSV, or XLSX without uploading your files.
This page came from hearing people complain about getting GPX from a watch into a clean map and spreadsheet, fighting with KML exports, and reformatting CSV columns by hand. So this tool was built to load, map, analyze splits, and export again — all privately in your browser.
Bring your own GPX, TCX, KML, CSV, or XLSX. The preview, stats, and exports all run locally on your device.
| Format | Best for | Pros | Watch outs |
|---|---|---|---|
| GPX | Universal tracks | Simple XML and wide support | Can get large for dense tracks |
| KML | Google Earth | Styled lines and placemarks | Heavier XML and style varies by app |
| TCX | Fitness workouts | Laps, HR, and cadence support | Support varies more than GPX |
| CSV / XLSX | Analysis and cleanup | Easy filtering and spreadsheet workflows | Needs correct field mapping |
Total distance, duration, average pace or speed, and elevation change. Units can switch between km and miles.
Per-km or per-mile time with cumulative distance. Useful for spotting surges, slowdowns, or hill sections.
My CSV won’t map. Make sure latitude and longitude columns are selected and numeric.
Times look wrong. Set the correct time format like ISO, Excel, Unix seconds, or Unix milliseconds.
Big files feel slow. Close heavy tabs and consider splitting or downsampling the route.
Do my files upload? No. Everything runs locally in your browser.
