How to create zebra stripes with conditional formatting
In this video, we'll look at how to use conditional formatting to shade every other row in a table. This is sometimes called "zebra striping".
In this spreadsheet, we have a table of employees with a small amount of formatting. To get shading on every other row, we could just convert this table to a proper Excel table using Control + T, then customize the format as desired.
This is a good option, especially if you want the table for other reasons as well.
However, you can also apply dynamic zebra striping with conditional formatting and a formula.
The classic formula for zebra striping uses the MOD function. MOD takes a number and a divisor, then returns the remainder. So, if I use the ROW function without a reference to get number of the current ROW, and then use 2 as the divisor, the MOD function returns zero when the row is an even number and 1 if not.
If I copy this formula across multiple cells, you can see we get rows of ones and zeros. We can use these results directly in a conditional formatting rule, since 1 and zero are equivalent to TRUE and FALSE.
So, to add the striping, I can just create a new conditional formatting based on a formula...then add the formula, and set a fill color.
If you'd rather shade even rows, just add "= 0" to the formula to change the logic.
Later versions of Excel allow you to use two special functions, ISODD, and ISEVEN in conditional formatting rules.
So, instead of this MOD formula, I could just use ISEVEN with ROW.
To shade odd, rows, I just need to replace ISEVEN with ISODD.
If you want to shade columns instead of rows, you can just substitute the COLUMN function for the ROW function
Finally, in case you ever want to create a checkerboard effect, you can use ROW and COLUMN together. The formula is simply + ROW + COLUMN, wrapped in ISODD or ISEVEN.
The Excel ROW function returns the row number for a reference. For example, ROW(C5) returns 5, since C5 is the fifth row in the spreadsheet. When no reference is provided, ROW returns the row number of the cell which contains the formula.
The Excel COLUMN function returns the column number for a reference. For example, COLUMN(C5) returns 3, since C is the third column in the spreadsheet. When no reference is provided, COLUMN returns the column number of the cell which contains the...
