It supports CSV, SpreadsheetML, PDF, and all file formats from Excel 97 to Excel 2007.

Changes:
A picture can now be added based on a desired range of cells as the data source. Some significant enhancements were made for shading a style’s fill effect for cells, opening CSV files with values longer than 32K in the cells, and copying table and list object formulae accordingly when inserting new rows. Refreshing PivotTables, saving to HTML, reading files, rendering Microsoft Excel 2007/2010 file formats, rendering PivotTables, converting Excel files to HTML format, rendering charts, rendering image files, and exporting to PDF were fixed
