What is new in this release?

We are pleased to announce the new release of Aspose.Cells for .NET 8.4.0 . This release contains many useful features and other enhancements including the long awaited feature to manipulate VBA codes embedded inside the spreadsheets. Many of the Aspose.Cells users had been waiting for this feature, and now it is available with the release of Aspose.Cells for .NET 8.4.0. The latest version has exposed a new namespace named Aspose.Cells.Vba and a few classes to provide the means to access the VBA code embedded inside the macro enabled spreadsheets, and to update the code as per your requirements. Aspose.Cells allows the users to extract Theme related data from Excel file. For example, you can extract Theme Name applied to workbook and Theme Color applied to cell or borders of the cell etc. Another worth mentioning feature is the support for Pivot Table removal. Aspose.Cells has provided this feature by exposing two new methods for the PivotTableCollection class that allows to delete a specific PivotTable from the collection depending upon the input parameter. Microsoft Excel has predefined layouts for the Pivot Tables as listed below. Upon choosing any of these layouts, Microsoft Excel applies formatting to the Pivot Tables accordingly.

- Compact Form
- Outline Form
- Tabular Form

Aspose.Cells for .NET 8.4.0 provides the same functionality while using the newly exposed methods for the PivotTable class that allows to dynamically set the layouts as discussed above. Detailed article and sample code snippets are available at Changing the Layout of Pivot Table. With the release of v8.4.0, the Aspose.Cells API has provided the DataBar.ToImage method to save the conditionally formatted DataBar in image format. Aspose.Cells can be used to add custom properties inside the workbook object which are visible in the Document Information Panel when accessed through Microsoft Excel using the File > Info > Properties > Show Document Panel menu. In the new version, we have also provided the following new enhancements. Customize the generated CSS file while saving Excel to HTML file format, Retain the Cell?s Number Format after using ImportTwoDimensionArray, Aspose.Pdf and other tools validates the output PDF/A-1B file by Aspose.Cells API and workbook?s RefreshChartCache works with regional and language settings. We have fixed a few exceptions that occurred while reading and writing Microsoft Excel file formats and HTML file format. We have also fixed the exceptions that occurred while manipulating Pivot tables in the template file and combining workbooks. In this release, several important issues have been addressed. For example, issues around reading/ writing Microsoft Excel file formats, combining worksheets, Smart Markers, manipulating PivotTables, applying formattings to the cells, using PageSetup options, rendering HTML file format, applying conditional formatting, manipulating shapes, rendering images from Excel worksheets, manipulating charts with formatting, rendering images files from charts and exporting Excel workbooks to PDF format have been resolved. We have also enhanced the Aspose.Cells formula calculation engine further and fixed a few relevant issues in this release. We have fixed an issue regarding customize row/column headers in the web based Grid control provided by Aspose.Cells for .NET.
