MOD and Conditional Formatting

I was told in a course that I could use MOD() for Conditional formatting - shading every other row -- but wasn't told how. Can someone please tell me how to do this?

Good morning,

Certainly. If you want to shade every other row use:

=MOD(ROW(),2)

You can use similar logic to shade every third row, every other column, etc.

Best of luck,

Where do I put the formula and how does it know to shade?

Sorry I left off the last of the formula.

It should read:

=MOD(ROW(),2)=1

Go to conditional formatting and select the option to use your own formula. Paste that in and set your formatting.

MOD takes the remainder. This takes the row # divided by two, so even rows will have a remainder of 0, while odd rows will have a remainder of 1. All of the 1's get formatted and all of the 0's are blank.
