IndexError: list index out of range

[Hyperrick]

Hello,

I want to use pyxlsb2 for reading an .xlsb file. I found some files which doesn't seem to open while other work. Opening with pyxlsb works, pyxlsb2 not.

I have two files:

1. x.xlsb (works)
2. y.xlsb (doesn't work)

Source code:

from pyxlsb2 import open_workbook

with open_workbook("y.xlsb") as wb:
    for sheet in wb.sheets:
        print(sheet)

I can't find any difference in the files. Their both are .xlsb. files. I need to see if the files have any hidden worksheets. This is not possible with pyxlsb only with pyxlsb2 as I know so far.

Best regards

Patrick
