Formatting Every Other Row

You can use Excel's conditional formatting feature to highlight every other row in a spreadsheet, similar to the old-style green bar paper. To do so, select the portion of the spreadsheet that you wish to format, and then choose Format | Conditional Formatting. Change Cell Value Is to Formula Is and enter this formula:
=MOD(ROW(),2) <> 0
Click the Format button, and then under Patterns select the color of your choice. Click OK twice.
