Google Health Profile Export Format
Google is deprecating the Fitbit API on September 30th, 2026. After this date, Fitbit data will only be available through Google Health. Please refer to the Migrating Fitbit to Google Health article for additional information.
This export contains the Google Health profile information for each participant who has connected a Google Health account — their age, account membership start date, and running/walking stride length. See Google's user profile documentation for how these values are calculated.
