KNIME Openpyxl - unable to read workbook

Hello,

I’m encountering an issue with KNIME openpyxl module. I’m attempting to load an excel workbook that is saved in the same folder as my project (and not corrupted).

wb = loadworkbook('file manipulation.xlsx', readonly=False)

However, I receive the below error message whenever I try it. This is strange because there’s nothing unusual about the workbook and the code works fine when in a standard Python environment. Is there any reason why this would cause be causing problems in KNIME?

:x: ValueError: Unable to read workbook: could not read worksheets from file manipulation.xlsx. This is most probably because the workbook source files contain some invalid XML. Please see the exception for more details. Traceback (most recent call last): File “”, line 3847, in File “”, line 27, in run_code File “”, line 3843, in returnexceltemplate File “”, line 92, in openopenpyxlfile File “C:\Users\Public\KNIME\bundling\envs\orgknimepythonscripting\Lib\site-packages\openpyxl\reader\excel.py”, line 346, in load_workbook reader.read() File “C:\Users\Public\KNIME\bundling\envs\orgknimepythonscripting\Lib\site-packages\openpyxl\reader\excel.py”, line 307, in read raise ValueError(

Any help would be much appreciated, thanks !
