How to Convert FIT to CSV

Why convert FIT to CSV?

FIT files are great for fitness devices but impossible to open in a spreadsheet. Converting to CSV gives you a simple, row-per-trackpoint format that you can open in Excel, Google Sheets, or load into Python with pandas.

This is useful for:

• Analyzing heart rate zones or pacing strategy across a workout
• Creating custom charts and visualizations
• Comparing data across multiple activities
• Academic or coaching research on training data

What data is included?

FitConvert exports every trackpoint with the following columns:

• timestamp — ISO 8601 format
• latitude and longitude — GPS coordinates
• altitude_m — elevation in meters
• heart_rate_bpm — heart rate
• cadence_rpm — cadence (running or cycling)
• speed_mps — speed in meters per second
• distance_m — cumulative distance in meters

Fields that aren't present in the original file are left blank, so the CSV still opens cleanly.
