# Add-ExcelDataValidationRule

## SYNOPSIS

Adds data validation to a range of cells

## SYNTAX

```text
Add-ExcelDataValidationRule [[-Range] <Object>] [-WorkSheet <ExcelWorksheet>] [-ValidationType <Object>]  [-Operator <ExcelDataValidationOperator>] [-Value <Object>] [-Value2 <Object>] [-Formula <Object>]  [-Formula2 <Object>] [-ValueSet <Object>] [-ShowErrorMessage] [-ErrorStyle <ExcelDataValidationWarningStyle>]  [-ErrorTitle <String>] [-ErrorBody <String>] [-ShowPromptMessage] [-PromptBody <String>]  [-PromptTitle <String>] [-NoBlank <String>] [<CommonParameters>]
```

## DESCRIPTION

Excel supports the validation of user input, and ranges of cells can be marked to only contain numbers, or date, or Text up to a particular length, or selections from a list. This command adds validation rules to a worksheet.

## EXAMPLES

### EXAMPLE 1

```text
PS\>Add-ExcelDataValidationRule -WorkSheet $PlanSheet -Range 'E2:E1001' -ValidationType Integer -Operator between -Value 0 -Value2 100 \`
     -ShowErrorMessage -ErrorStyle stop -ErrorTitle 'Invalid Data' -ErrorBody 'Percentage must be a whole number between 0 and 100'
```

This defines a validation rule on cells E2-E1001; it is an integer rule and requires a number between 0 and 100. If a value is input with a fraction, negative number, or positive number &gt; 100 a stop dialog box appears.

### EXAMPLE 2

```text
PS\>Add-ExcelDataValidationRule -WorkSheet $PlanSheet -Range 'B2:B1001' -ValidationType List  -Formula 'values!$a$2:$a$1000'
       -ShowErrorMessage -ErrorStyle stop -ErrorTitle 'Invalid Data' -ErrorBody 'You must select an item from the list'
```

This defines a list rule on Cells B2:1001, and the posible values are in a sheet named "values" at cells A2 to A1000 Blank cells in this range are ignored.

If $ signs were left out of the fomrmula B2 would be checked against A2-A1000, B3, against A3-A1001, B4 against A4-A1002 up to B1001 beng checked against A1001-A1999

### EXAMPLE 3

```text
PS\>Add-ExcelDataValidationRule -WorkSheet $PlanSheet -Range 'I2:N1001' -ValidationType List    -ValueSet @('yes','YES','Yes')
        -ShowErrorMessage -ErrorStyle stop -ErrorTitle 'Invalid Data' -ErrorBody "Select Yes or leave blank for no"
```

Similar to the previous example but this time provides a value set; Excel comparisons are case sesnsitive, hence 3 versions of Yes.
