This example converts the contents of the Clipboard, which contains a space-delimited text table, into separate columns on Sheet1. You can create a simple space-delimited table in Notepad or WordPad (or another text editor), copy the text table to the Clipboard, switch to Microsoft Excel, and then run this example.
Worksheets("Sheet1").Activate
ActiveSheet.Paste
Selection.TextToColumns DataType:=xlDelimited, _
ConsecutiveDelimiter:=True, Space:=True
