Fitbit's interface only lets you export one month of data at time. This Python script exports all months.
- Selenium (
pip install seleniumshould do it).
- An empty
Downloadsfolder (there will be one CSV file for every month of data the script retrieves).
- Chromedriver on the same folder your script is (or provide the full path to it on line 11).
- Tweak lines 6, 7, 8 to provide your e-mail, password, and how many months back you want to go.
