Using Google Sheets for conditional formatting based on a range’s own values is simple. Formatting based on another range of cells’ values is a bit more involved. Following are step-by-step instructions to format a range of cells using values in another range of cells.

## What is conditional formatting

Conditional formatting is used to highlight to the reader of the spreadsheet certain values that meet certain criteria. It can be used to show items over/under a certain amount, later/earlier than a certain date, or only the widgets sold by Joan.

## Conditional formatting based on another cell

#### Our objective in this example is to highlight all of the dates on which Joan had a sale.

Select the range that you want to have highlighted. Even though you are going to be referencing another range of cells, you still only need to select the range that you are going to be formatting. In this example, we’ll be highlighting the date column.

Click *Format* in the top menu then *Conditional formatting…*

The Conditional Formatting menu option will pop up a *Conditional format rules* menu on the right side of the screen (on the desktop version of Sheets).

Click the plus sign to begin adding the rule. In the drop-down menu for *Format cells if* choose the last option which is *Custom formula is*.

In the box that appears below *Custom formula is* enter `=B1="Joan"`

. Note that you have to start the formula with a = sign just like any other spreadsheet formula. Also, note that you need to surround the word Joan with “s since it is a word instead of a number.

Now you have the sales data with dates highlighted on which Joan made sales.

## Extending to the entire row

## Nadena Gibson says:

Is there a way to do this if a cell contains one of two things. For instance, in your example data is there a formula that says highlight the cell in column A if column B says “Joan” or “Gill”?

## Prolific Oaktree says:

Yeah, sure. Just start it with the OR function.

## Scott Azevedo says:

Rather than format a color in, can I format a 1 instead. =B2″furlough”. If B2=furlough, then I want a 1 in B1. Is this doable? Thanks

## Prolific Oaktree says:

That wouldn’t require conditional formatting. Just use an IF statement.

## n says:

we cannot study your sheet because “format” is grayed out

Thank you for your guide, it was very helpful, but I have a question!

Backstory – I record all my Apple Activity stats on a Google Sheet per month. I have columns for everything I like to keep an eye on (move ring, exercise ring, water, steps etc). Most of them I can have finite numbers for, e.g. the Stand ring is always complete at 12 hours, so I can have conditional highlighting on ‘greater than or equal to 12’ which works for all conditional highlighting except 1 column.

I would like to conditionally format column D (the number that Apple Health gives me for my Move stat) based on whether it’s equal to or greater than column c (which is the Move goal I set myself and this changes every week).

Because this number changes, I can’t put ‘is greater than or equal to 600’ for example, because this might not always be the number in column C. I can’t seem to find a way to be able to have column D dependent on column C for each cell.

I don’t know if I’m explaining this right but hopefully you can understand that I mean! I know it must be simple, but I’ve read so many guides and I just can’t work it out!

Thanks ðŸ™‚

## Prolific Oaktree says:

You have to use a custom formula which is the last option in the conditional formatting drop down. Then do something like IF(C2

## Iver says:

Is there a way to use the empty/not empty formula for another cell? I would like to color one cell if another cell is empty. Is that possible?

## Prolific Oaktree says:

Sure. You can use the ISBLANK function and just reference that other cell. Enter the formula using the Custom formula input box.

## Anthony Tiseo says:

What if you want to format it if multiple cells fit a condition? What about a percentage of cells in a range?

## Prolific Oaktree says:

You can do all of that. Start by looking into the AND function. You’ll have to wrap a few functions together inside of it. Practice in a spreadsheet cell first then copy and paste into conditional formatting.
