问题
I have tried using August William's solution to this issue, but that also didn't work. I am not switching workbook types, i.e. .xlsm to .xlsx, which appears to be a separate issue. I have looked through Openpyxl's Manual trying to find maybe a bug report or bug fix, but to no avail. The below is my very simple code. Following that is the python error message which results in a workbook being created, but it is corrupted and fails to load. Any help is appreciated. -Thanks!!
from openpyxl import Workbook
dashbrd = Workbook()
fp = dashbrd.active
fp.title = 'Sheet Name Goes Here'
fp['A1'] = 'Header'
fp['B1'] = '2nd Header'
fp['C1'] = '3rd Header'
fp['D1'] = '4th Header'
fp['E1'] = '5th Header'
fp['F1'] = 'You get the idea'
fp['G1'] = 'Another Header'
fp['H1'] = 'Blah blah blah'
fp['I1'] = 'Yadda yadda yadda'
dashbrd.save("S:\\folder1\\folder2\\folder3\\MyBook.xlsx")

Like I said above , yesterday I had the same problem ..I found the solution in this link:
https://python-forum.io/Thread-Need-help-in-understanding-this-particular-Traceback-TypeError
In reference to this error : TypeError: got invalid input value of type , expected string or Element
In summary the solution was to install openpyxl to another version :
pip uninstall openpyxl
pip install openpyxl==3.0.1

I can't find a good reference, but I recall having stumbled upon the same, and the solution was to use the older format (.xls, which is a completely different format) instead. Seems like a generic problem of openpyxl that wasn't resolved at the moment.
A working way to append to .xlsx (works for me):
from openpyxl import load_workbook
writer = pd.ExcelWriter(filename, engine='openpyxl')
try:
# try to open an existing workbook
writer.book = load_workbook(filename)
# get the last row in the existing Excel sheet
# if it was not specified explicitly
if startrow is None and sheet_name in writer.book.sheetnames:
startrow = writer.book[sheet_name].max_row
# truncate sheet
if truncate_sheet and sheet_name in writer.book.sheetnames:
# index of [sheet_name] sheet
idx = writer.book.sheetnames.index(sheet_name)
# remove [sheet_name]
writer.book.remove(writer.book.worksheets[idx])
# create an empty sheet [sheet_name] using old index
writer.book.create_sheet(sheet_name, idx)
# copy existing sheets
writer.sheets = {ws.title: ws for ws in writer.book.worksheets}
except FileNotFoundError:
# file does not exist yet, we will create it
pass
if startrow is None:
startrow = 0
# write out the new sheet
df.to_excel(writer, sheet_name, startrow=startrow, **to_excel_kwargs)
# save the workbook
writer.save()

same problem for me not able to reopen a file created by openpyxl version > 3: in 3.0.3: File "D:\MyProg.py", line 251, in chargerSynthese self.wbs = load_workbook(filename=self.nomfichierXLSX) File "D:\MyPython\python3.8.2-x64\lib\site-packages\openpyxl\reader\excel.py", line 314, in load_workbook reader.read() File "D:\MyPython\python3.8.2-x64\lib\site-packages\openpyxl\reader\excel.py", line 279, in read self.read_worksheets() File "D:\MyPython\python3.8.2-x64\lib\site-packages\openpyxl\reader\excel.py", line 227, in read_worksheets ws_parser.bind_all() File "D:\MyPython\python3.8.2-x64\lib\site-packages\openpyxl\worksheet_reader.py", line 426, in bind_all self.bind_cells() File "D:\MyPython\python3.8.2-x64\lib\site-packages\openpyxl\worksheet_reader.py", line 337, in bind_cells for idx, row in self.parser.parse(): File "D:\MyPython\python3.8.2-x64\lib\site-packages\openpyxl\worksheet_reader.py", line 153, in parse row = self.parse_row(element) File "D:\MyPython\python3.8.2-x64\lib\site-packages\openpyxl\worksheet_reader.py", line 264, in parse_row self.row_counter = int(attrs['r']) ValueError: invalid literal for int() with base 10: '2.0'
attrs={'r':'2.0'} don't know where it come from (but origin in a save worksheet by openpyxl 3.0.3) then when you do this int(attrs['r']) in _reader.py: crash!
solution back to 2.6.4 version!

reply to myself!
openpyxl 3.0.3 works well but is less permissive than 2.6 versions, here is my test code you must put int in row= , not float
from openpyxl import __version__
from openpyxl import load_workbook
from openpyxl import Workbook
wbs = Workbook()
wbs.active.title = 'titi'
mycell=wbs['titi'].cell(row = 1.0, column = 1)
mycell.value=22
wbs.save('toto.xlsx')
print('openpyxl __version__:',__version__)
wbi = load_workbook(filename='toto.xlsx')
for i in range(0,30):
wbi['titi'].append([i,'tata'])
wbi.save('toto.xlsx')
