Comma-Delimited Differences for PC and Mac

Excel allows you to save worksheet data in a comma-delimited format, so you can use it with other programs. Comma-delimited files are often referred to as CSV (comma-separated value) files, and are often used for exchanging data between programs.

When selecting how to export you data, you need to be sure that you pick the export format that is appropriate for the system on which it will be used. There are actually three CSV formats included with Excel:

• CSV (Comma delimited) (*.csv)
• CSV (Macintosh) (*.csv)
• CSV (MS-DOS) (*.csv)

You can choose any of these CSV options by using the Save As Type drop-down list at the bottom of the Save As dialog box. There are subtle differences between all three formats, but for most people, the first and third formats are essentially the same—they both work on the PC. The second format, for the Macintosh, is worth noting, however.

If your export file is destined for use on a Macintosh, you should choose the second CSV option. This option results in a CSV file where each record (each line in the file) is terminated with a carriage return, as expected by the Mac. In the PC world, lines are terminated with a carriage return/line feed combination, which can muck things up on the Macintosh.

If you are creating the CSV export file on the Mac for later use on the PC, you will want to make sure that you select a CSV format appropriate for the target system. The Mac includes CSV options for both Windows and MS-DOS systems. You should be able to choose either option and have the file work just fine.
