I have heard that PanX allows importing contents of the clipboard into a database, but I can’t seem to find out how to do this.
Create a new empty Pan X document. Then use the menu command File > Import > Import Text File into Current Database … . The text import wizard appears and allows to import from the clipboard (see the Import Data menu).
You could also write a simple procedure to import the data into an existing database or create a new database and then import the data:
newdatabase importtext clipboard()
