Auto-Fit Columns, Rows While Importing HTML & Get List of Fonts Used in Spreadsheet using Java

Aspose team is pleased to announce the new release of Aspose.Cells for Java 17.2.0. This release includes many new features and enhancements along with some critical bug fixes that further improve the overall stability of the API. The release notes also list any changes made to the public API such as added, renamed, removed or deprecated members as well as any non-backward compatible change made to Aspose.Cells for Java. This release offers the metered licensing mechanism in parallel to its traditional licensing. In order to provide the usage based licensing, Aspose.Cells for Java has exposed the Metered class that allows the developers to set public and private keys by calling its setMeteredKey method. The metered licensing system monitors the regular usage of Aspose.Cells API and keeps track of the Aspose API licenses. It has exposed the getFonts method for the Workbook class. The Workbook.getFonts method returns the list of individual fonts used to format the cell contents for a given spreadsheet. The list returned by the Workbook.getFonts method is in the form of an array of type com.aspose.cells.Font. The newly exposed method is useful in scenarios where the developers require to extract the list of the fonts used in a particular spreadsheet. The extracted list can further be used to match the available fonts on the machine before rendering the spreadsheet. This is because, if Aspose.Cells APIs are not able to find the required fonts, they try to replace the required font with some other suitable font which is present on the system. By comparing the system’s font list against the fonts used in the spreadsheet, the developers can devise some mechanism to either pick the required fonts from a custom location or substitute a particular font with a list of available fonts. Aspose.Cells for Java has now added the HTMLLoadOptions.AutoFitColsAndRows property which indicates if the API should auto-fit columns and rows while importing the HTML in its object mode. The Boolean type property has the default value as false which means that the cell heights & widths will be imported as they are, however, when the aforementioned property is set to true, the API tries to adjust the column widths and row heights according to the contents. Latest revision of Aspose.Cells for Java has exposed the Cells.textToColumns method in order to mimic the Excel’s Text to Columns feature. Excel provides this feature from the command group Data Tools under the Data tab as highlighted in the snapshot on blog announcement page.This release has exposed the WarningCallback property for the LoadOptions class in order to get or set the warning callbacks. Developers have to implement the IWarningCallback interface in order to get custom warnings in their applications. This revision of Aspose.Cells for Java has exposed Boolean type TrimLeadingBlankRowAndColumn property for the TxtSaveOptions class that indicates whether leading blank rows and columns should be trimmed like Excel does while exporting data to CSV or Tab-delimited formats. The default value of aforementioned property is false. In case the data on the worksheet does not start from the first cell, that is: A1, the Excel application removes the leading blank rows and columns while exporting the data to CSV or Tab-delimited formats, however, Aspose.Cells APIs by default, retain the blank rows & columns for the same sample in order to keep the data location retained if the exported CSV or Tab-delimited files have to be imported back using Aspose.Cells APIs. It has enhanced its core for more stability as well as fixed a few critical bugs. Moreover, there are numerous minor enhancements in order to improve the overall usage of the API. It enhanced Support to load Excel 2016 chart types, Enhanced HTML rendering engine for shapes & handled a few exceptions.
