Macros for validating data in excel
So, for weekdays (Mon to Fri) the result of the formula should be less than 6, and for weekends (Sat and Sun) greater than 5.
Allow only workdays: In many situations, you may want to use today's date as the start date of the allowed date range.
If you want to validate cells with your own criteria, create a custom validation rule based on a formula.
Here's how: Optionally, you can add a custom input message and Error alert that will show up when the user selects the validated cell or enters invalid data, respectively.
Data Validation Example | Create Data Validation Rule | Input Message | Error Alert | Data Validation Result Use data validation in Excel to make sure that users enter certain values into a cell. On the Data tab, in the Data Tools group, click Data Validation.
In this example, we restrict users to enter a whole number between 0 and 10.
Please pay attention that we lock the range with absolute cell references (A:$A) and use a relative reference for the top cell (A2) to get the formula to adjust properly for each cell in the validated range.
Excel date validation provides quite a lot of predefined criteria to restrict users to entering only dates between the two dates you specify, greater than, less than, or equal to a given date.
In yesterday's tutorial we started to look at Excel Data Validation - what its purpose is, how it works, and how to use built-in rules to validate data in your worksheets.
But this can be easily done with a custom data validation formula based on the ISNUMBER function, like this one: Where D2 is the uppermost cell of the selected range.
If all values in a certain range should begin with a particular character or substring, then do Excel data validation based on the COUNTIF function with a wildcard character: In the above formula, the LEFT function extracts the first 3 characters from cell A2, and EXACT performs a case-sensitive comparison with the hard-coded substring ("AA-" in this example).
To better illustrate the point, please consider the following example.
Supposing, you want to restrict data entry in cells D2 to D5 to whole numbers between 1 (minimum value) and the result of dividing A2 by B2.
