Eesh. I had a look at your file and Strava have localised the column headers in the csv files! I am going to have to switch to using indexes if non-en and hope they don’t insert columns. I will sort that out on Wednesday.
head -1 activities.csv
Aktivitäts-ID,Aktivitätsdatum,Name der Aktivität,Aktivitätsart,Aktivitätsbeschreibung,Verstrichene Zeit,Distanz,Max. Herzfrequenz,Relative Leistung,Pendeln,Hinweis zur Privatsphäre für Aktivitäten,Aktivitätsausrüstung,Dateiname,Sportlergewicht,Fahrradgewicht,Verstrichene Zeit,Bewegungszeit,Distanz,Höchstgeschw.,Durchschnittliche Geschwindigkeit,Höhenzunahme,Höhenunterschied,Min. Höhe,Max. Höhe,
I am going to be sorting it out for German on Sunday. Part of that will be detecting unrecognised languages and saving the column headers so I can quickly support all the others that Strava uses.
