Restricting input to specific values

Limiting input length
Data validation is used to limit the length of input in a cell. Such as a maximum character limit for text input.
Validating data based on formulas

How to use data validation in Excel?
After understanding what is data validation in excel, let’s get to know how to use it. What are the different steps in using data validation in excel? Let’s understand all the steps needed for applying the data validation option in excel, the types of data validation and the data validation process.
Steps used in the data validation process
In Brief, we can say that to use data validation in Excel, you can follow these steps:
- Select the cell or range of cells where you want to apply data validation.
- Go to the “Data” tab in the Excel ribbon and click on “Data Validation” in the “Data Tools” group.
- In the “Data Validation” dialog box, select the type of data you want to allow, such as whole numbers, decimals, dates, or times.
- Set additional criteria or rules, such as minimum or maximum values, specific text or values, or custom formulas.
- Specify the error message to display if the data entered does not meet the validation criteria.
- Click the “OK” tab so that data validation can be applicated to the selected cells.
- Once data validation is applied to a cell or range of cells, users can only enter data that meets the specified criteria. If they attempt to enter data that does not meet the validation rules, they will see an error message explaining why the data is invalid.
Data validation process
Launch data Validation Tab
Data validation in excel starts with selecting the range of cells in your data or worksheet where you want to apply data validation. Then go to the data validation tab in the ribbon above the worksheet. Click on that and launch the dialogue box for data validation in excel. This data validation tab has three options which are data validation, circle invalid data and clear validation circles. To launch the next step which is the setting tab you need to click on the data validation option out of these three options.
This part of the data validation process allows you to set validation criteria for your data. when you click on the setting tab, there are eight options for choosing the criteria or we can say that it’s an excel validation list from the table. These are
1. Any value
Any value in the excel validation list from the table means no validation or specific criteria at all. Basically, it removes the restriction and allows any value in the selected cell or range of cells.
2. Whole Number
This option in the excel validation list from the table allows the user to enter only whole numbers. After clicking the whole number you will get more options to apply rules for making it more specific related to whole numbers, for example, less than, more than, equal to and in between are the options which help in making data more accurate.
This option allows the user to enter data with decimals. Hence, It’s similar to whole numbers only difference is here user can enter very specific and accurate data.
However, in this option of data validation user has to choose an option from the drop-down list. Thus we can consider this as a typical type of data validation where the user has to choose one option from the predefined data.
This option allows users to enter the data in the form of date value only. However, we can create the validation criteria like previous dates or future dates also we can set the range of dates as one option.
Moreover the next option which is time is similar to the date one. Here user can enter the data in the form of dates for instance 9 am, 8 pm etc.
7. Text length
Moreover, this data validation option allows the user to enter the data of a particular text length which means data entered by the user is validated by the number of digits or characters.
However, this is an advanced option for data validation where you can define a custom formula to validate the data entered by the user.
After choosing the right validation criteria in allow dropdown, the next step is to go to the input message tab.
Input Message Tab
The input tab in data validation is an optional tab. It can display the message to the user to explain what kind of data is allowed to enter. You just need to click on the input message tab . Then choose the title and message you want to display.
Error Alert Tab
This is again an optional tab. The error alert tab is used to display the message when a user tries to enter invalid data. To activate this option u need to check out the ta” Show error alert after invalid data is entered”. Along with the message you can also choose the style of the message also. Enter the title and message you want to show and press ok to complete the action.
