How to validate a cell value

If you are designing an excel sheet for other users to enter data, or even for your own use, it is a good idea to use the data validation feature to insure that only correct data will be entered. hear is how you do it:

  1. Select the cell you want to validate.
  2. On the Data menu, click Validation, the Data Validation dialogue box will be shown.

  1. Click the Settings tab.
  2. Specify the type of validation you want. Suppose you have a numeric value and you want to allow only values between 1 and 99, then:
    1. In the Allow combo box select ‘Decimal’.
    2. In the Data combo box select ‘Between’.
    3. In the Minimum edit box enter ‘1’.
    4. In the Maximum edit box enter ‘99’.

To show an error message when an invalid data is entered:

  1. Click the Error Alert tab.
  2. Fill the Title and Error Message edit boxes with appropriate text. (See example).

To remove data validation, click the Clear All button in the Settings tab.
