Export Workout from Health App in .tcx Format?

Hello dgford,

Thank you for using Apple Support Communities! I understand that you're wanting to know if you can export the health data on your iPhone in .TCX format instead of XML in order to use it with Garmin Connect.

Health data is exported in XML format by default, and there's no way to choose another format when exporting:

Since Garmin Connect does not support this file type, you would need to utilize a third-party method of converting it like you're currently doing:

Take care.

Hi dgford,

You're very welcome. Please reach out if you have questions we can help answer in the future.

Cheers!
