OpenXml Validation Spreadsheet Value Between Two Numbers – C#

Hi everyone,

Just a quick post on how to validate a numeric cell to ensure that the value is between two numbers when using OpenXml:

// Restrict min and max values
var dataValidations = new DocumentFormat.OpenXml.Spreadsheet.DataValidations { Count = 0 };
DocumentFormat.OpenXml.Spreadsheet.DataValidation dataValidation;
dataValidation = new DocumentFormat.OpenXml.Spreadsheet.DataValidation {
Type = DataValidationValues.Decimal,
AllowBlank = false,
SequenceOfReferences = new ListValue() { InnerText = $”{columnName}2:{columnName}1048576″ },
Operator = DataValidationOperatorValues.Between,
Formula1 = new Formula1 { Text = “10 “},
Formula2 = new Formula2 { Text = “20 “},
};
dataValidations.Append(dataValidation);
dataValidations.Count++;
worksheetPart.Worksheet.Append(dataValidations);

The snippet above will ensure that any values are between 10 and 20. I didn’t come across any examples for this while searching, so hopefully this will be able to help someone else out!

Thanks,
Chris
