How to remove illegal characters so a dataframe can write to Excel

Question

I am trying to write a dataframe to an Excel spreadsheet using ExcelWriter, but it keeps returning an error:

openpyxl.utils.exceptions.IllegalCharacterError
         


        

Answer 1

The same problem happened to me. I solved it as follows:

1. install python package xlsxwriter:

pip install xlsxwriter

2. replace the default engine 'openpyxl' with 'xlsxwriter':

dataframe.to_excel("file.xlsx", engine='xlsxwriter')
