Convert Garmin FIT files to GPX, TCX, JSON, or CSV in seconds.
Output format
GPS Exchange — universal
Convert turns a Garmin or Wahoo FIT file into the format you need — GPX for universal compatibility, TCX for structured workout data, JSON for developers, or CSV for spreadsheets. Drop the file, pick a format, and download.
It runs entirely in your browser, so your activity is never uploaded. Power, heart rate, cadence, and temperature are carried through wherever the target format supports them.
FIT is a compact Garmin format that many apps and maps will not open. GPX is the universal GPS exchange format — converting lets you upload to services, edit in route tools, or open the track anywhere.
GPX for the widest compatibility, TCX when you need structured laps and workout data, JSON for developers working with the raw data, and CSV to open the records in Excel or Google Sheets.
Yes, where the target format supports it. GPX and TCX carry heart rate, cadence, and power via extensions; CSV and JSON expose every recorded field as columns or keys.
No. The conversion runs entirely in your browser, so the file never leaves your device.
