Hey friends—back in Google Sheets again. In this tutorial I show you how to use conditional formatting to automatically change how cells look based on the numbers you type in, so your spreadsheet basically “calls out” what matters without you having to scan every row. I use a super simple sales tracker example (team members across a few months) to keep it practical, because conditional formatting is one of those features that instantly makes data easier to read. First, I select a range (in my example it’s B2 to D5), then go to Format > Conditional formatting. From there, I create an easy rule: anything less than 0 turns red—because negative numbers are really bad and I want to spot a bad month at a quick glance. Then I add another rule for the same range: anything greater than or equal to 1,000 turns green, so standout months pop immediately. I also show where the existing rules live, how to add another rule, and how to delete a rule with the trash can. The big takeaway is simple: using color-based rules helps you digest data really, really quickly and draws your attention to the cells that are important.
