Open the text file as a Word Processing document. (Select Word Processing as document type.)
Choose Find/Replace from the Edit menu.
Enter: "," (quote comma quote) in the Find box, and enter: \\t (the symbol for a tab) in the Change box. Click on Change All.
Now do one more Find/Replace, this time enter: " (quote) in the Find box, and enter a space in the Change box. Click on Change All.
Choose Save as... from the File menu for this document and save it as Text.
Now you have a tab separated text document. When you open this document as a Database (select Database as document type) it will create the fields and convert the data automatically.
This works great for data such as names and addresses, but can be a little tricky if you are importing fields with quotes or tabs contained in the text.
