You are using an Output Excel node to write the output, but reading it in using a CSV File node; It's a different format, so it is complaining a lot, and it just happens that the Excel file has 18,000 lines in it.
You want to either use an Excel File node to read the output you are creating, or save the output using the Delimited Output node to create a CSV file.
Sorry it took me so long to get back to you on this.
