Aspose.Cells for .NET logo Aspose.Cells for .NET 8.1.0 has been released. The new release contains many useful improvements. It also includes several fixes and other enhancements. Before you go ahead and start exploring the new features and other enhancements, we will list here some major features and other enhancements in this month’s release.

New Enhancements to the PivotTable Class

Aspose.Cells has exposed the getter/setters for the DisplayNullString & NullString properties for the PivotTable class to handle the pivot table option “For empty cells show” offered by Microsoft Excel. These properties allow users to set display option for the empty cells inside the Pivot Table to any specified string. Please check the detailed article on Setting Pivot Table Option - For empty cells show.

Enhancements to the HtmlSaveOptions Class

Aspose.Cells for .NET API now provides ExportHiddenWorksheet property exposed by the HtmlSaveOptions class. The Boolean property allows users to choose whether to render the hidden worksheets or not. The default value is true which means that the hidden worksheet will be rendered as HTML; switching the to false excludes hidden worksheets from the rendering process. More details on this topic can be found on the Prevent Exporting Hidden Worksheet Contents while Saving to HTML.

Added Cell.StringValueWithoutFormat Property

The StringValueWithoutFormat property has been added to the Cell Class, in order to let developers retrieve the cell value without formatting applied. The code snippet below demonstrate how to use Cell.StringValueWithoutFormat property as compared to the Cell.DisplayStringValue by creating a spreadsheet from the scratch and applying the number format to one of the cells.

 //Create an instance of Workbook 
Workbook book = new Workbook();

//Access first worksheet
Worksheet sheet = book.Worksheets[0];

//Access A1 cell
Cell cell = sheet.Cells["A1"];

//Put a value cell and convert it to number
cell.PutValue("123456", true);

//Create a new Style object and add it to Workbook's Style Collection
Style style = book.Styles[book.Styles.Add()];

//Set Number format for Style object
style.Number = 3;

//Set the style of A1 cell
cell.SetStyle(style, new StyleFlag() { NumberFormat = true });

//Get formatted string value
string formatted = cell.DisplayStringValue;

//Get un-formatted string value
string unformatted = cell.StringValueWithoutFormat;
