Openpyxl.utils.exceptions.IllegalcharacterError

Question

I have the following code to write processed words into excel file. The words are about 7729

From openpyxl import *
book=Workbook ()
sheet=book.active
sheet.title="test"
for x in range (7729):
    sheet.cell (row=1,column=x+1).value=x
book.save ('test.xlsx')

This is the code I used looks like. But when I run it it gives me an error that says

openpyxl.utils.exceptions.IllegalCharacterError

This is my first time using this module, I would appreciate any kind of help.

with open("temp.txt") as myfile :

    while text !="":
            sheet.cell (row=1,column=x+1).value=str(text).encode("ascii",errors="ignore")
            x+=1
            text = myfile.readline()

book.save ('test.xlsx')

Answer 2

You missed to add the value for cell sheet.cell (row=1,column=x+1).value =

Try like this

from openpyxl import *
book = Workbook ()
sheet = book.active
sheet.title = "test"
for x in range (7):
    sheet.cell (row=1,column=x+1).value = "Hello"
book.save ('test.xlsx')
