Need to import multiple dates? The guide below explains how to add extra rows.
The whole process takes under two minutes. Here's exactly what to do once you have your file.
Enter your date, weight, height (so BMI auto-calculates), and optionally your body fat percentage in the tool above. Hit Download Garmin CSV. The file saves instantly — nothing is sent to a server, it all runs locally in your browser.
Go to connect.garmin.com/modern/import-data in your browser and log in. This is Garmin's official import page — it accepts both CSV and FIT files. You must use the web browser version; the Garmin Connect mobile app doesn't support CSV imports.
Drag your downloaded file onto the upload area on the Garmin Connect import page, or click the area to browse and select it. Garmin will detect it as body composition data automatically.
After the import, go to Health Stats → Weight in Garmin Connect. Your entry should appear on the correct date. If you included body fat %, it shows in the same section.
Download one CSV from the tool, then open it in a plain text editor — Notepad on Windows, or TextEdit on Mac set to plain text mode. Each row below the header is one measurement. Add as many rows as you need, one per line, following the format:
DD-MM-YYYY,weight_in_kg,bmi,body_fat_%15-04-2025,78.5,24.2,18.315-04-2025,78.5,,DD-MM-YYYY — day first, then month, then year. If you manually edit the file, follow this exactly. Getting it wrong will either cause the import to fail or silently drop the entry.Wearable Converter migrates your entire Fitbit history — weight, sleep, steps, heart rate, floors — into Garmin Connect.
