What is new in this release?
We are pleased to announce the new release of Aspose.Cells for .NET 7.7.1. It has been released with over 80 useful new features, enhancements and bug fixes. This new release supports reading large Excel files with LightCells API. This is a useful feature. Sometimes you need to read data from a huge Microsoft Excel workbook with millions of records and you always worry about the performance. You want it to take less time and memory to process big files. The LightCells API is useful in that scenario: to read huge Excel spreadsheets, it uses less memory, so you get better performance and efficiency. Another valuable feature is to find the cells with some particular style or formatting. Aspose.Cells supports finding all cells that have a common style or formatting. It provides the FindOptions.Style property which you can use to specify the style to search cells for. You can now create transparent images of Microsoft Excel worksheet. Sometimes, you need to generate an image of your worksheet as a transparent image. For example, you might want to apply transparency to all the cells which have no fill color. Aspose.Cells provides the ImageOrPrintOptions.Transparent property which applies transparency to a worksheet image. When this property is false, then the cells with no fill color are drawn with white background, and when it is true, cells with no fill color are rendered transparent. In this version, we have refactored the PivotTables module. We've made tremendous enhancements and fixed several issues. Several important issues and other enhancements have been addressed in this release as well. For example, issues around reading and writing Microsoft Excel file formats, manipulating conditional formatting, rendering and manipulating pivot tables, rendering images from Excel worksheets, reading and writing HTML files, rendering shapes and controls, Smart Markers, manipulating embedded OLE objects, rendering and manipulating charts, rendering images files from charts and exporting Excel workbooks to PDF format have been resolved. A few improvements are also made pertaining to the formula calculation engine of Aspose.Cells for .NET, it now supports the BITAND function (Microsoft Excel 2013).
