Customizing Data Validation Criteria - Data Validation in Excel

Excel is a powerful tool that can be used to store and manage large amounts of data. With the help of data validation, you can ensure that the data entered in your Excel sheet meets specific criteria. In this tutorial, we will explore how to customize data validation criteria in Excel.

Getting Started with Customizing Data Validation Criteria

Syntax:

The syntax for customizing data validation criteria in Excel involves the following steps:

1. Select the cell or range of cells where you want to apply data validation.
2. Go to the Data tab in the ribbon and select Data Validation.
3. In the Data Validation dialog box, select the type of validation.
4. Customize validation criteria using the input options.

Example:

Let's assume we want to validate an email address entered in a cell. Here are the steps to customize data validation criteria in Excel:

1. Select the cell where you want to apply data validation.

2. In the Data tab, select Data Validation.

3. In the Data Validation dialog box, select Custom under Validate.

4. In the Formula field, enter the validation criteria as shown below:

   =AND(ISERROR(FIND("@",A1,FIND(".",A1))=FALSE),LEN(A1)-LEN(SUBSTITUTE(A1,"@",""))=1)
   

5. Customize other settings as needed, such as Error Alert and Input Message.

Output:

The output of the custom data validation is a cell or range of cells that only accept data that meets specific criteria. If the data entered does not meet the validation criteria, an error message is displayed.

Explanation:

Excel's data validation tool allows you to customize validation criteria in various ways. By default, you can use various built-in validation types, such as whole numbers, dates, and text lengths. However, you can also customize validation criteria using formulas such as AND, OR, and NOT.

By customizing validation criteria, you can ensure that the data entered in your Excel sheet is consistent, accurate, and error-free.
