getting this error. do you have an idea?

Traceback (most recent call last): File ConvertGoogleHistory.py", line 52, in for row in reader: File ConvertGoogleHistory.py", line 33, in make_reader yield [time.isoformat(), float(longitude), float(latitude)] ValueError: could not convert string to float: '12.0679108Â'

I got that error as well. For some reason it's seeing a "Â" character in the long + lat data before the degree sign. Not sure why that's the case. If you add lines to remove that character from both the long and lat in each segment type (vist, activity, position, and timelinePath) after the long+lat are created it will then work.

ie:
if 'visit' in segment:
latitude, longitude = segment['visit']['topCandidate']['placeLocation']['latLng'].replace('°', '').split(', ')
latitude = latitude.replace('Â', '')
longitude = longitude.replace('Â', '')

Worked as charm, thank you as lot.

@sitz I get this error
