GPX FIT TCX to CSV Converter
Email [email protected]. Include the Windows version, the app version from About, and what you expected to happen. A short description is enough. Do not attach a track that shows your home unless we ask and you agree.
What the free app does
You can open GPX, FIT, TCX, KML and KMZ files, review the route, elevation, point table, laps and data checks, and save one file at a time as CSV. You can choose columns, metric or imperial units, and how times are written.
What Pro adds
Pro is a one-time unlock at $9.99 in the Microsoft Store, with no subscription. It adds spreadsheet workbooks, GeoJSON, GPX and KML output, converting a folder, merging files, a privacy zone around the start and end, point thinning, and a GPS-only filter. The purchase button uses the Microsoft Store price shown on your account. Restore purchase checks the same Microsoft account. Pro is not live until the parent app is published, the add-on is released, and a Store-installed purchase and restore have been tested.
If a file will not open
The app reads activity, course and route data in the formats above. A damaged file is reported in the list instead of crashing the window. FIT files with a checksum mismatch are still read when the contents can be parsed, and the Checks tab says so. Files with no track points can still show waypoints.
If the numbers differ from your watch
Distance prefers a steady distance recorded in the file. Speed prefers a recorded speed. Climb ignores elevation changes under 3 metres. Moving time counts gaps where the point-to-point speed is above 0.5 m/s. Another device can use a different threshold, so the totals will not always match.
