When i am trying to delete some sheet from excel file i am getting “XML file reading error” i am using below python code to delete sheet with the name of “Evaluation”.

import openpyxl as xl

wb1 = xl.load_workbook(“file location with path”)

for i in wb1.sheetnames:
if(i.find(“Evaluation”) == 0 or i.find(“Evaluation”.lower()) == 0):
del wb1[i]

wb1.save(“file saving location”)

Hi @shubham_knime -

Can you upload an example workflow and Excel file that reproduces the problem? It seems like this mystery file “xmlfile.xml” is missing, but you don’t show the exact path that you’re trying to read.

Maybe @mlauber71 will have some insight, he is quite familiar with openpxyl. But having an actual workflow for us to debug is crucial :slight_smile:

I think the “del” command would remove an entire object in Python in this case a definition of the workbook you just set. I fear this might cause problems. This command might be better:
