Error com_error: (-2147221005, 'Invalid class string', None, None) while writing dataframe into excel binary notebook

问题

I am trying to write a data frame into excel sheet(xlsb), which is having formulas, using xlwing library:

app = xw.App()

book = xw.Book('ABC.xlsb')

sheet = book.sheets('SL Dump')

sheet.range('A1').values=final_merge_dataframe

After running the above code, I am getting this error:

com_error: (-2147221005, 'Invalid class string', None, None)
