Hi @arjundelara, can you confirm if your Server has access to the folder from which the workflow is trying to read the excel files? If access isn't a problem, please check the URL you are using in the Input and Output tools to ensure you are using relative network paths.
If this is a Dynamic Input tool you are using, make sure to include the Table Names (excel sheet names) as part of the file location URL, i.e. \\someNetworkPath\sample.xlsx|||Sheet1
Do I need to add the sheet name in the macro "update value" position? I have the same problem
