Easy way to show .fit files in Excel to create own plots?

Hi,

i am very suprised that it seems that there is no easy way to export the raw data from recorded activities to excel.

I just want to create my own plots and comparisons which is actually not possible with garmin connect. I found out that it is possible to view the tcx files easily in excel, but in these files not all data is in.
I have an app on my garmin which is called Auxiliary Heart Rate. This app builts up a connection to my chest strap and records the Heart rate from the chest strap whereas the watch is recording the Heart rate from the optical sensor.  So I have 2 Heart rates recorded at the same time. So far I know both heart rates are saved in the .fit file. In garmin connect I can also show both heart rates at the same time, but the problem is, that they are on 2 different y-axis, so you cannot compare them. I would need both on the same y-axis, but that is not possible. Thats the reason why I want to create my own plots in excel.

I found somethung on github for converting a fit file to csv, but thats much to complicated for me, i am no IT specialist Disappointed

I do not understand why there is no function in garmin connect for an export to excel. That cannot be so difficult?!

Maybe you have an advice for me

Thanks and regards,

Peter
