This script combines Google Fit data from the "Daily activity metrics" folder of a Google Takeout export into a single CSV for further analysis or other uses. The main intent was using the Health CSV Importer app for iOS, which will import CSV data into Apple Health, allowing someone to export Google Fit data into Apple Health.

Thanks to Ben on Stack Exchange for the initial script.

As of my conversations with Lionheart Software on November 8, 2021, below are the currently supported date and time formats which can then be used in combination with each other e.g. yyyy-MM-dd HH:mm:ss.SSSZ

I have made recommendations to the developers to include timezone separators like +/- to more closely align with the ISO 8601 standard as this would alleviate some import issues with the format Google currently uses.

• MM-dd-yyyy (e.g. 04-16-2020)
• dd-MM-yyyy (e.g. 16-04-2020)
• yyyy-MM-dd (e.g. 2020-04-16)
• yyyy-dd-MM (e.g. 2020-16-04)
• yyyyMMddHHmmssZ
• MMMM d, yyyy (e.g. April 16, 2020)

• HH:mm
• hh:mm a
• HH:mm:ss
• hh:mm:ss a
• HH:mm:ss Z
• hh:mm:ss a Z
• HH:mm:ssZ
• HH:mm:ss.SSSZ
