How do you convert FIT to CSV? Use our free FIT to CSV Converter to instantly transform your Garmin FIT files into CSV format. Simply upload your FIT file, click convert, and download the CSV file ready for analysis in Excel or Google Sheets.
The conversion process preserves all your workout data including timestamps, GPS coordinates, heart rate, power, cadence, and speed—making it perfect for detailed training analysis.
Why Convert FIT Files to CSV?
FIT (Flexible and Interoperable Data Transfer) files are the native format used by Garmin devices and many fitness trackers. While efficient for storage, FIT files are binary and can't be opened directly in spreadsheet applications.
Converting to CSV gives you:
- Full data access: View every data point from your workout
- Spreadsheet compatibility: Open in Excel, Google Sheets, or LibreOffice
- Custom analysis: Create your own charts, graphs, and calculations
- Data portability: Share and archive your training data in a universal format
- Research applications: Export data for academic or personal research projects
What Data Is Preserved in the CSV?
When you convert a FIT file to CSV, these data fields are extracted:
| Data Field | Description | Common Uses |
|---|---|---|
| Timestamp | Date and time for each record | Time-based analysis |
| Latitude/Longitude | GPS coordinates | Route mapping |
| Altitude | Elevation in meters | Climb analysis |
| Heart Rate | BPM from heart rate monitor | Zone analysis |
| Power | Watts from power meter | Training load |
| Cadence | Steps/revolutions per minute | Running/cycling form |
| Speed | Velocity in km/h or mph | Pace analysis |
| Temperature | Ambient temperature | Environmental factors |
| Distance | Cumulative distance | Progress tracking |
The exact fields depend on what sensors your device recorded. Indoor activities may not have GPS data, while outdoor runs without a power meter won't have power data.

Common Questions
Can I convert FIT files from any device?
Yes! The converter works with FIT files from:
- Garmin watches (Forerunner, Fenix, Venu, etc.)
- Garmin bike computers (Edge series)
- Wahoo devices
- Other FIT-compatible fitness trackers
What if my FIT file has no GPS data?
Indoor activities (treadmill, stationary bike) won't have GPS coordinates. The CSV will simply have empty latitude/longitude columns, but all other sensor data will be preserved.
Can I convert the CSV back to FIT?
CSV to FIT conversion requires specialized tools and isn't commonly needed. If you need to move data between platforms, consider using our other converters like FIT to GPX or FIT to TCX.
How large can my FIT files be?
The browser-based converter handles typical workout files easily. Very long activities (24+ hours) may take a few extra seconds to process.
