Workflow cleans Excel data by isolating duplicates and appending only unique records to the cleanup sheet

Describe the problem/error/question

I have been trying to automate the workflow by creating the worksheet in workbook and trying to add the headers in the created worksheet but not able to do that as there is no node or the excel nodes available didn’t provide the functionality, tried by writing the code as well as by creating the table its creating headers with column name column1, column2, column3 and so on but unable to update the header name as required. so is there any approach to automate header creation and append the data after that

What is the error message (if any)?

cannot match the properties

Please share your workflow
