Hi am a novice at coding. When I try to analyze my data of my excel file I get an error regarding utf-8: " UnicodeDecodeError: 'utf-8' codec can't decode byte 0x82 in position 16: invalid start byte". But when i save it as a csv utf-8 file I get "AttributeError: 'str' object has no attribute 'update' "

my .xlsx data is structured as such:
A
0
1
2
3
4
5
6
7
8
9
10
11
12
13

15
16
17
If you could help me out I'd be grateful. Thank you!
