We are pleased to announce the new release of Aspose.Cells for .NET 8.8.0. This release contains some valuable features along with critical bug fixes and other enhancements. As per default behaviour, if a numeric value is larger than the threshold, the API converts such values to exponential notation while importing HTML segment/files to Aspose.Cells object model. In past, we could use the HTMLLoadOptions.ConvertNumericData property to control the conversion of textual values to numeric data, however, this approach has its own drawbacks. For instance, if there are more than one columns containing the numeric values, setting the HTMLLoadOptions.ConvertNumericData property to false will direct the Aspose.Cells APIs to keep all values in textual format. In such case, all formatting from the numeric values will be lost. In order to handle the situations where users wish to retain the format of all numeric values as well as keep the data in its original state, the Aspose.Cells for .NET 8.8.0 has exposed the HTMLLoadOptions.KeepPrecision property. The Boolean property allows controlling the conversion of large numeric values to exponential notation. When set to true, the numeric values larger than 15 digits will be imported as it is. A simple usage scenario demonstrating the usage of HTMLLoadOptions.KeepPrecision property to avoid the conversion of large numbers to exponential notation while importing data from Html is provided on blog announcement page. It has exposed the HTMLLoadOptions.DeleteRedundantSpaces property to control the preservation of redundant spaces after the line break tag (
tag) in HTML. If the aforementioned property is set to true the API will delete all the redundant spaces while importing the HTML in Aspose.Cells object mode. The HTMLLoadOptions.DeleteRedundantSpaces property has the default value as false, that means, all the redundant spaces are preserved in the resultant spreadsheet. The most notable other enhancements in this release includes, Ability to use image markers while grouping data in smart markers, ability to find Query Tables and List Objects related to external data connections and improved PDF rendering engine for chart objects. This release includes several enhanced features and bug fixes as listed below
