What is new in this release?

The long awaited version of Aspose.Cells for Java 8.6.3 has been released. This month’s release contains many useful features and improvements along with some critical bug fixes. Aspose.Cells APIs provide a set of classes for the developers to influence the spreadsheet loading mechanism. While using the LoadOptions & LoadDataOptions classes, the developers can set a number of options such as force the API to load specific worksheets, where the worksheets can be specified via their indices or names. It has exposed another useful property for the LoadDataOptions class which allows to load only the visible worksheets from an existing spreadsheet, where the hidden worksheets will be simply ignored and will not be available in the Aspose.Cells object model for any processing. The newly exposed property is of type Boolean; setting it to true means that the API will ignore the hidden worksheets and load only the visible worksheets for further processing. It has exposed a method that can be used to create an object of the Style class that corresponds to one of the built-in styles offered by the Excel application. The Workbook.createBuiltinStyle method accepts a constant from the enumeration BuiltinStyleType. Please note, with previous releases of the Aspose.Cells APIs, same task could be accomplished via StyleCollection.createBuiltinStyle method but as the recent releases of Aspose.Cells APIs have removed the StyleCollection class from the public API therefore the newly exposed Workbook.createBuiltinStyle method can be considered as an alternative approach to achieve the same goal. The most notable enhancements in this release includes, It has exposed the ImportTableOptions.setHtmlString attribute which directs the API to parse the HTML tags while importing data onto the Worksheet and set the parsed result as cell value. Please note, Aspose.Cells APIs already provide the Cell.setHtmlString attribute to perform this task for a single cell, however, while importing data in bulk, the ImportTableOptions.setHtmlString attribute (when set to true) tries to parse all the supported HTML tags and sets the parsed results to the corresponding cells, This release has addressed some formatting issues reported for the XML Spreadsheet 2003 to XLSX conversion and Enhanced the PDF rending engine to maximize the fidelity for the Excel Chart objects. This release includes several enhanced features and bug fixes as listed below
