How to use excel function if

The IF function returns a true value when the specified condition is met, otherwise it returns a false value. The syntax is: IF(logical_test, value_if_true, value_if_false). After entering the logic test, enter true and false values ​​respectively based on its results. The IF function supports nesting and can implement complex conditional judgments.

Usage of Excel function IF

Introduction to IF function

The IF function is a conditional judgment function in Excel, used to return different values ​​based on specified conditions. The syntax is:

<code>IF(logical_test, value_if_true, value_if_false)</code>

Use steps

1. Enter logical test: Specify the condition to be judged, and the result is TRUE or FALSE.
2. Enter true value: The return value returned if the logical test is TRUE.
3. Enter false value: The return value returned if the logical test is FALSE.

Example

Suppose there is data 100 in cell A1, we want to determine whether it is greater than or equal to 50, and return the corresponding value based on the result. You can enter the following formula:

<code>IF(A1>=50, "合格", "不合格")</code>

If the value in A1 is greater than or equal to 50, the formula will return "Qualified"; otherwise, it will return "Unqualified".

Nested IF function

IF functions can be nested to create more complex conditional judgments. For example:

<code>IF(A1>=50, "合格", IF(A1>=80, "优秀", "良好"))</code>

This formula determines whether the value in A1 is greater than or equal to 50, and returns the corresponding evaluation. Returns "Excellent" if greater than or equal to 80; "Good" if greater than or equal to 50 but less than 80; otherwise, returns "Failed".

Note

• Logical tests must be Boolean (TRUE or FALSE).
• True and false values ​​can be numbers, text, or references.
• IF function can only return two values. If you need to return multiple values, you can use the IFERROR function or nested IF functions.
