how to save the print data in excelshet using windows forms?

If you mean you want to print a file and save the printed data to an Excel file, you can try capturing the printed data by handling the PrintDocument.PrintPage event; and then within the event handler, try to use the printed data and save it to Excel file as shows in the following forum:

I did not try this, but this might work.

I remember that leadtools had virtual printing features that can capture printed data and save it to different document formats. I found the following link that might help:

Thanks in advance.
