Hello
In relation to the previous query sharing a xlsx file which has this issue.

About code even trying to load the file and save it without any changes the issue arises sharing that code snippet as well, using spire xls python.

Code:
wb = Workbook()
wb.LoadFromFile('test/Test_Spire.xlsx')

wb.SaveToFile('test/demo.xlsx')
