Analyses using Apple Watch data

Download the data from the Apple Health app on your iPhone. You can do this by going to the Health app, clicking on your profile picture in the top right corner, and selecting "Export All Health Data". This will create a zip file that you can share with yourself. Download the zip file and extract the contents. The important file in this extract is export.xml. I have this file saved in a folder data/apple_health_export in this repository. I have the data folder in the .gitignore file so that the data is not uploaded to this GitHub repository.

To convert the export.xml file to a CSV file, I found this great resource with sample code. I've copied their parsing function to convert_xml_to_csv.py in this repository.

To see the xml data as json within the terminal, run the following command in the Terminal:

python convert_xml_to_csv.py data/apple_health_export/export.xml

To convert the xml data to a csv file, run the following command in the Terminal:

python convert_xml_to_csv.py data/apple_health_export/export.xml | jq -r '[.startDate, .endDate, .type, .unit, .value] | @csv' > data/apple_health_export/export.csv

This requires the JSON parser jq to be installed. I installed jq via Homebrew on my Mac with: brew install jq.
