If you're trying to make a large spreadsheet easier to read, you'll likely want to format certain items to highlight what's important for the reader. While you could go in and format each cell by hand, Google Sheets allows you to automate this task with Conditional Formatting Rules.
You can set up a variety of rules for Sheets to obey, including determining whether a cell is empty or not, if it contains a date that is before or after a specific point in time or if it contains text that starts or ends with a particular phrase. Here are our step-by-step instructions for how to use conditional formatting in Google Sheets.
