I've just moved to Garmin last month, and would like to bring over some historic data from Fitbit. I've exported everything through Google Takeout, and created CSVs that on the face of it should be able to be imported to Garmin Connect.
Every file I try results in the unhelpful message "An error occurred with your upload. Please try again." No option for further details or help on what the error was!
I can't find much about the proper structure of the file on any formal help page - only forums or reddit/etc. See below for what I'm trying. (I've cut it back to only one date with dummy data, just to get the thing working before I try to bring in 6 years' worth of stuff! This forum also won't seem to let me attach the file as a sample)
Anyone had any luck with this? I'm not holding my breath - so many other similar threads seem to have gone dead.
This is the file content, saved as a UTF-8 CSV:
