To export your Surfer profile to an ASCII data file:
- Select the Profile you wish to export in the Contents window.
- In the Properties window, on the Plot tab, click the Save to File button in the Export profile data field.
- In the Save As dialog, give your output file a name and click Save.
This will give you a DAT file, but you can easily open this file in Surfer's worksheet and use the File | Save As command to save to another ASCII format like XLSX or CSV, if you have need for a specific type of output file.
