Reproduce Steps

Here is the code: CellRangeAddressList addressList = new CellRangeAddressList(); addressList.AddCellRangeAddress(1, 12, 1, 12); XSSFDataValidationHelper helper = new XSSFDataValidationHelper(pSheet); XSSFDataValidationConstraint constraint = (XSSFDataValidationConstraint)helper.CreateExplicitListConstraint( listConstraintValues); XSSFDataValidation validation = (XSSFDataValidation)helper.CreateValidation(constraint, addressList);

validation.ShowErrorBox = true; validation.CreateErrorBox("Title", pErrorMsg); validation.SuppressDropDownArrow = pIsSuppressDropDownArrow; pSheet.AddValidationData(validation);

Issue Description

if listConstraintValues contains double quote (") in a form that c# can handle (\"), then excel will return error. Excel uses double quote different way. See excel attached: M2 cell should be validated Without double quote it works fine. Error.xlsx
