Trying to read MS Excel file, version 2016. File contains several lists with data. File downloaded from DataBase and it can be opened in MS Office correctly. In example below I changed the file name.
EDIT: file contains russian and english words. Most probably used the Latin-1 encoding, but encoding='latin-1' does not help
import pandas as pd
with open('1.xlsx', 'r', encoding='utf8') as f:
data = pd.read_excel(f)
Result:
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xa8 in position 14: invalid start byte
Without encoding ='utf8'
'charmap' codec can't decode byte 0x9d in position 622: character maps to <undefined>
P.S. Task is to process 52 files, to merge data in every sheet with corresponded sheets in the 52 files. So, please no handle work advices.
The problem is that the original requester is calling read_excel with a filehandle as the first argument. As demonstrated by the last responder, the first argument should be a string containing the filename.
I ran into this same error using:
df = pd.read_excel(open("file.xlsx",'r'))
but correct is:
df = pd.read_excel("file.xlsx")
Most probably you're using Python3. In Python2 this wouldn't happen.
xlsx files are binary (actually they're an xml, but it's compressed), so you need to open them in binary mode. Use this call to open:
open('1.xlsx', 'rb')
There's no full traceback, but I imagine the UnicodeDecodeError comes from the file object, not from read_excel(). That happens because the stream of bytes can contain anything, but we don't want decoding to happen too soon; read_excel() must receive raw bytes and be able to process them.
Most probably the problem is in Russian symbols.
Charmap is default decoding method used in case no encoding is beeing noticed.
As I see if utf-8 and latin-1 do not help then try to read this file not as
pd.read_excel(f)
but
pd.read_table(f)
or even just
f.readline()
in order to check what is a symbol raise an exeception and delete this symbol/symbols.
