Aspose.Cells is a .NET component for spreadsheet reporting without using Microsoft Excel. It supports a robust formula calculation engine, pivot tables, VBA, workbook encryption, named ranges, spreadsheet formatting, drawing objects like images, OLE objects, and importing or creating charts. You can also create Excel files using a designer spreadsheet, smart marker, or API and apply formulae and functions. It supports CSV, SpreadsheetML, PDF, and all file formats from Excel 97 to Excel 2007.

Changes:
In this release, several important issues have been addressed. For example, issues around formatting cells, rendering PivotTables and charts, rendering Excel files, and rendering image files from charts / worksheets have been resolved. Issues pertaining to the formula calculation engine have also been fixed. Pivot table borders were incorrectly visible, and green ellipse word art/picture was incorrectly rendered around the chart; this is now fixed
