Apple Health to Garmin CSV (Python Version)

🩺→🖥→ 📊 A lightweight Python script to convert Apple Health export data into a Garmin-compatible CSV for weight tracking.

📊 What it does

This script parses export.xml from Apple Health and extracts:

• Body weight (kg)
• Body Mass Index (BMI)
• Body Fat Percentage (%)

Then it generates a fitbit_full.csv file compatible with Garmin Connect's Fitbit CSV import.
