Hi I am trying to convert my df to binary and store it in a variable.
my_df:
df = pd.DataFrame({'A':[1,2,3],'B':[4,5,6]})
my code:
import io
towrite = io.BytesIO()
df.to_excel(towrite) # write to BytesIO buffer
towrite.seek(0) # reset pointer
I am getting AttributeError: '_io.BytesIO' object has no attribute 'write_cells'
Full Traceback:
AttributeError Traceback (most recent call last)
<ipython-input-25-be6ee9d9ede6> in <module>()

I solved the issue by upgrading pandas to newer version.
import io
towrite = io.BytesIO()
df.to_excel(towrite) # write to BytesIO buffer
towrite.seek(0)
print(towrite)
b''
print(type(towrite))
_io.BytesIO
if you want to see the bytes-like object use getvalue,
print(towrite.getvalue())
