Why logical functions handle conditions in Google Sheets - Why Use It

Introduction

Logical functions in Google Sheets help you check if something is true or false. They let you make decisions in your spreadsheet, like showing different results based on conditions.

When you want to check if a number is greater than another and do something based on that.

When you need to see if a cell is empty or has a value before calculating.

When you want to combine multiple conditions, like checking if a score is above 50 and attendance is above 80%.

When you want to return different text or numbers depending on a condition, like 'Pass' or 'Fail'.

When you want to highlight or filter data based on true/false checks.

Steps

Step 1: Click

- a cell where you want the result

The cell is selected and ready for input

Step 2: Type

- the selected cell

The formula bar shows your typed formula

💡 Start with an equal sign (=) to tell Sheets you are entering a formula

Step 3: Enter

- the formula: =IF(A1>10, "Yes", "No")

The cell shows 'Yes' if A1 is greater than 10, otherwise 'No'

💡 IF is a logical function that checks a condition and returns one value if true, another if false

Step 4: Try

- other logical functions like AND, OR

You can check multiple conditions together, for example: =AND(A1>10, B1<5) returns TRUE only if both are true

Before vs After

Before

Cell A1 has the number 8, cell B1 is empty

After

Cell C1 with formula =IF(A1>10, "Yes", "No") shows 'No' because 8 is not greater than 10

Settings Reference

Formula input

📍 Formula bar

Where you type logical functions and formulas

Default: Empty cell

Calculation settings

📍 File > Settings > Calculation

Controls when formulas recalculate

Default: On change

Common Mistakes

Typing the formula without the equal sign, like IF(A1>10, "Yes", "No")

Sheets treats it as text, not a formula, so it does not calculate

Always start formulas with =, like =IF(A1>10, "Yes", "No")

Using wrong quotation marks or missing them around text values

Sheets will show an error or treat text incorrectly

Use straight double quotes " " around text in formulas

Summary

Logical functions let you check conditions and make decisions in your spreadsheet.

They return true/false or different results based on what you want to test.

Always start formulas with = and use correct syntax for conditions.
