Public API and Backwards Incompatible Changes

The following is a list of 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. If you have concerns about any change listed, please raise it on the Aspose.Cells support forum.

Added HTMLLoadOptions.AutoFitColsAndRows Property

This release of the Aspose.Cells for Java API has 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 the contents.

Here is the simple usage scenario of the HTMLLoadOptions.AutoFitColsAndRows property.

 // Create an instance of HTMLLoadOptions

HTMLLoadOptions loadOptions = new HTMLLoadOptions();

// Set the AutoFitColsAndRows property to true


// Create an instance of Workbook and load HTML while passing

// the object of HTMLLoadOptions class created above

Workbook book = new Workbook(dir + "sample.htm", loadOptions);

Added WorkbookSettings.WarningCallback & LoadOptions.WarningCallback Properties

Aspose.Cells for Java 17.02.0 has exposed the WarningCallback property to the LoadOptions and WorkbookSettings classes in order to get or set the warning callback. Developers have to implement the IWarningCallback interface in order to get custom warnings in their applications.

Here is a simple usage scenario of LoadOptions.WarningCallback property to get warnings when an input spreadsheet contains duplicate named ranges.

 public class WarningCallback implements IWarningCallback


	public void warning(WarningInfo warningInfo)


        if (warningInfo.getWarningType() == WarningType.DUPLICATE_DEFINED_NAME)


            System.out.println("Duplicate Defined Names Found as " + warningInfo.getDescription());




Here is how to use the custom class defined above.

 // Create an instance of LoadOptions class

LoadOptions options = new LoadOptions();

// Set the WarningCallback property to custom class

options.setWarningCallback(new WarningCallback());

// Load a sample spreadsheet in an instance of Workbook while 

// passing the object of LoadOptions class as defined above

Workbook book = new Workbook(dir + "sample.xlsx", options);

Added Cells.textToColumns Method

Latest revision of Aspose.Cells for Java APIs have exposed the Cells.textToColumns method in order to mimic the Excel’s Text to Columns feature. Excel provides this feature from Data Tools under the Data tab. Please note, in order to split the contents of a column to multiple columns, the data should contain a specific delimiter such as a comma (or any other character) based on which the API tries to split the contents of a cell to multiple cells.

Here is a simple usage scenario to demonstrate the usage of newly exposed API.

 // Create an instance of Workbook and load a sample

Workbook book = new Workbook(dir + "sample.xlsx");

// Retrieve the cells collection of the first worksheet in the sample

Cells cells = book.getWorksheets().get(0).getCells();

// Create an instance of TxtLoadOptions

TxtLoadOptions options = new TxtLoadOptions();

// Specify the separator


// Split the data in range B2:B4

cells.textToColumns(1, 1, 3, options);

Added Workbook.getFonts Method

Aspose.Cells for Java 17.02.0 has exposed the getFonts method for the Workbook class. The Workbook.getFonts method returns the list of individual fonts used to format the cells contents of a given spreadsheet. The return type of the aforementioned method is an array of typeFont class.

Following code snippet demonstrates the usage of Workbook.getFonts method.

 // Create an instance of Workbook and load a sample

Workbook book = new Workbook(dir + "sample.xlsx");

// Retrieve the list of fonts used in spreadsheet

Font[] fonts = book.getFonts();

// Iterate the list and write font name

for (int i = 0; i < fonts.length; i ++)


	Font font = fonts[i];



Added TxtSaveOptions.TrimLeadingBlankRowAndColumn Property

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.

Here is a simple usage scenario of the TrimLeadingBlankRowAndColumn property.

 // Create an instance of Workbook and load a sample

Workbook book = new Workbook(dir + "sample.xlsx");

// Create an instance of TxtSaveOptions

TxtSaveOptions options = new TxtSaveOptions();

// Set TrimLeadingBlankRowAndColumn property to true


// Export to CSV format while removing the leading blank rows & columns + "output.csv", options);

Added BuiltInDocumentPropertyCollection.Revision Property and Obsoleted BuiltInDocumentPropertyCollection.RevisionNumber Property

Please use BuiltInDocumentPropertyCollection.Revision property instead.

Added Shape.TextShapeType Property

The Shape.TextShapeType property gets or sets the preset text shape type from a list of predefined types stored in AutoShapeType enumeration.
