What data is included in the CSV file?

The CSV file includes timestamps, GPS coordinates, heart rate, power (if available), cadence, speed, altitude, and other metrics from your FIT file.

Can I open the CSV file in Excel?

Yes, the CSV file can be opened in any spreadsheet software including Microsoft Excel, Google Sheets, and LibreOffice Calc.

Will I lose any data during conversion?

The converter preserves all essential workout data. Some device-specific metadata might not be included as it's not relevant for analysis.

How do I analyze FIT data in Excel after conversion?

After converting to CSV, open the file in Excel, then use charts for visualizing heart rate or power over time, and formulas like AVERAGE and MAX for calculating key metrics. See our Excel analysis guide for detailed instructions.

What is the difference between FIT and CSV formats?

FIT is a compact binary format used by Garmin devices that stores structured workout data efficiently. CSV is a text-based format that can be opened in any spreadsheet application, making it ideal for data analysis and visualization.

Can I convert multiple FIT files to CSV at once?

Yes! Our converter supports bulk processing. You can select up to 10 FIT files at once and convert them sequentially. Each file is processed individually, and you can download them all when complete.

How do I export FIT files from Garmin Connect?

Log into Garmin Connect, open the activity you want to export, click the gear icon in the top right corner, and select "Export Original" to download the .fit file to your computer.

Our FIT to CSV Converter extracts every data field from your Garmin FIT file and writes it as a CSV ready to open in Excel, Google Sheets, or any spreadsheet tool — all processing happens in your browser, so your file is never uploaded to a server.

What Data Is Included in the CSV?

All fields present in your FIT file are exported. Common fields include:

Data Field	Description
Timestamp	Date and time for each recorded data point
Latitude / Longitude	GPS coordinates in decimal degrees
Altitude	Elevation in metres (barometric or GPS-derived)
Heart Rate	Beats per minute from chest strap or wrist sensor
Speed	Instantaneous speed in m/s (or converted to km/h)
Distance	Cumulative distance from the start of the activity
Cadence	Steps per minute (running) or RPM (cycling)
Power	Watts from a power meter (cycling/running, if available)
Temperature	Ambient temperature in °C (if recorded by the device)
Lap Markers	Auto or manual lap boundaries with lap summary data

How to Analyze Your FIT Data in Excel or Google Sheets

Once converted, open the CSV in Excel or Google Sheets to create heart rate charts, calculate average power, or build pace-over-distance graphs. Use Excel's Insert > Chart to plot any column against the timestamp. For more detailed analysis workflows, see our step-by-step guides:
