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”)
print(wb1.sheetnames)

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

wb1.close()
wb1.save(“file saving location”)

I am writing this code python script node and when i am executing this code in the node i am getting below error.

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

@shubham_knime you could take a look at this example removing a specific sheet from an excel file:

use Python package openpyxl to remove an existing worksheet from an Excel file...

@shubham_knime

del wb1[i]

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:

wb.remove_sheet(i)
