I would like to write it in an excel sheet. What I tried:

from pandas import ExcelWriter

writer = ExcelWriter('spread32.xlsx')
yourdf.to_excel(writer)
writer.save()

But nothing written in the excel file, it remains empty.

Is it because I am using jupyter notebook? The excel file already exists.

Answer 1

for completeness sake:
when you save a file with a relative path, it will be in relative to where you are running from. its not always immediately clear where jupyter is running so either use a full path or do %pwd to check where you actually are
