Copying from the ERP system to the clipboard is a very ineffective way of handling data. Any system worth its salt should be able to export to a CSV file.
You can then use a variety of techniques to load that CSV file into Excel.
If you need to clean up the data, i.e. get rid of specific columns, you could use Power Query. This is a free add-in from Microsoft for Office 2010 and 2013 and it is built into Excel 2016 in the Data ribbon as "Get and Transform".
The beauty of Power Query is that it records every step you take to transform your data and whip it into the shape you need it to be for your Excel processing. Every step of Power Query will be recorded and can be repeated.
Let your ERP system create a CSV file in a location like S:\ERP\Exports\JSDiver\TheData.csv
You can then point Power Query to open that file, delete columns and do other stuff, like removing unwanted characters, extracting years and months from dates to help with grouping for reports, etc.
Next week/month, let the ERP system dump another file in exactly the same path with exactly the same file name. Open the Excel file with the Power Query and click "Refresh All" and the data from the CSV file will be read, shaped, transformed, just as you did manually the first time.
This may take a while to sink in.
Power Query is the best thing that has happened to Excel in the last 5 years. If you work with data, Power Query is an invaluable tool.
