While you are downloading the latest build, here is a look at the most worth mentioning features in this release

Create Chart PDF with Desired Page Size

You can create chart’s PDF file with your desired page size using Aspose.Cells and specify how you want to align the chart inside the page as top, bottom, center, left, right etc. Besides this, the output chart can be created in stream or on disk. Please see the following article for more detail on this topic.

Rotate Text with Shape inside the Worksheet

You can add text inside any shape using Microsoft Excel. If you add shape using the older Microsoft Excel 2003, then text will not rotate with shape. But if you add shape using newer versions of Microsoft Excel e.g. 2007, 2010, 2013 or 2016 etc. then text will be rotated with shape. You can control if the text should rotate with shape or not using the ShapeTextAlignment.RotateTextWithShape property.

Read/Write TSV (Tab-Separated Values) Files

TSV files are used to contain spreadsheet data but without any formatting. The format is same with Tab Delimited where data is arranged in rows and columns such as tables and spreadsheets. To open tab delimited files, developers should call the LoadOptions method and select the TSV value, predefined in the FileFormatType enumeration. Please see the following sample code and the related article for your reference.

// Creating TSV LoadOptions object.
LoadOptions loadOptions = new LoadOptions(FileFormatType.TSV);

// Creating an Workbook object with TSV text file path and the LoadOptions object.
Workbook workbook = new Workbook(dirPath + "SampleTSVfile.tsv", loadOptions);

// Print success message.
System.out.println("TSV workbook has been opened successfully.");

Get All Hidden Rows Indices after Refreshing AutoFilter

When you apply auto filter on worksheet cells, then some of the rows get hidden automatically. But it might be the case that some of the rows are already hidden manually by MS Excel end user and they are not hidden by auto filter feature. It therefore makes difficult to know which of the rows are hidden by auto filter and which rows are hidden manually by MS Excel end user. Aspose.Cells deals with this problem using the int[] AutoFilter.refresh(boolean hideRows) method. This method returns the row indices of all the rows that are hidden by auto filter and not by manual way in MS Excel.

Avoid Blank Page in Output Pdf when there is Nothing to Print

When the Excel file is empty and user saves it to PDF using Aspose.Cells, it renders blank page in output PDF. Sometime, this default behavior is undesirable. Aspose.Cells provides the PdfSaveOptions.OutputBlankPageWhenNothingToPrint property to deal with this issue. If you will set it as false, then CellsException will occur whenever there is nothing to print in the output PDF.

Find Type of X and Y Values of Points in Chart Series

Sometime, you want to know the type of X and Y values of chart points in a series. Aspose.Cells provides ChartPoint.XValueType and ChartPoint.YValueType properties that can be used for this purpose. Please note, you will have to call Chart.calculate() method before you could use these properties effectively.

Get HTML5 string from Cell

Aspose.Cells returns the HTML string of the cell using the string Cell.getHtmlString (boolean html5) method. If you pass “false” as parameter, it will return you Normal HTML but if you pass “true” as parameter, it will return Html5 string.

Hiding Overlaid Content with CrossHideRight while saving to Html

When you save your MS Excel file to HTML, you can specify different cross types for cell strings. By default, Aspose.Cells generates HTML as per Microsoft Excel but when you change cross type to CrossHideRight then it hides all the strings from the right side of the cell which are overlaid or overlapping with cell string.

  • Hiding Overlaid Content with CrossHideRight while saving to Html

Specify the Language of the Excel File using Built In Document Properties

You can change the Language of MS Excel file by right clicking the file and then selecting Properties > Details and then editing the Language field. Please use BuiltInDocumentPropertyCollection.Language property to change it programmatically using Aspose.Cells APIs.

Specify the Far East and Latin Name of the Font in Text Options of Shape

Sometimes you want to display text in Far East language font e.g. Japanese, Chinese, Thai etc. Aspose.Cells provides TextOptions.FarEastName property that can be used to specify the font name of Far East language. Besides, you can also specify the Latin font name using TextOptions.LatinName property. Please see the following article for more detail on this topic.

Save Workbook to Strict Open XML Spreadsheet Format

Aspose.Cells allows you to save the workbook in Strict Open XML Spreadsheet format. For that purpose, it provides the Workbook.Settings.Compliance property. If you set its value as OoxmlCompliance.ISO_29500_2008_STRICT, then the output Excel file will be saved in Strict Open XML Spreadsheet format.

// Create workbook.
Workbook wb = new Workbook();

// Specify - Strict Open XML Spreadsheet - Format.
wb.getSettings().setCompliance(OoxmlCompliance.ISO_29500_2008_STRICT);

// Add message in cell B4 of first worksheet.
Cell b4 = wb.getWorksheets().get(0).getCells().get("B4");
b4.putValue("This Excel file has Strict Open XML Spreadsheet format.");

// Save to output Excel file.
wb.save(dirPath + "outputSaveWorkbookToStrictOpenXMLSpreadsheetFormat.xlsx", SaveFormat.XLSX);

Specify Individual or Private Set of Fonts for Workbook Rendering

Generally, you specify the fonts directory or list of fonts for all the workbooks but sometime, you have to specify individual or private set of fonts for your desired workbooks. Aspose.Cells provides IndividualFontConfigs class that can be used to specify the individual or private set of fonts for your workbook. Please see the following article for more detail on this topic.

Add Cells to Microsoft Excel Formula Watch Window

Microsoft Excel Watch Window is a useful tool to watch the cell values and its formulas conveniently in a window. You can open the Watch Window using Microsoft Excel by clicking the Formulas > Watch Window. It has Add Watch button that can be used to add the cells for inspection. Similarly, you can use Worksheet.getCellWatches().add() method to add cells into Watch Window using Aspose.Cells API. Please see the following article for more detail on this topic.

Working with Slicers using Aspose.Cells API

Slicers are used to filter data quickly. It provides buttons that user can click to filter Table or Pivot Table data. Whenever, Slicer buttons are selected or deselected, it shows the current filtering state that helps the user to understand what precisely has been filtered in the Pivot Table. Please see the following articles that explain how to work with Slicers using Aspose API.

The following sample code loads an Excel file that contains an existing Slicer. It unselects the 2nd and 3rd items of Slicer to refresh it. It then applies formatting/style of the Slicer and finally describes on how to remove the Slicer.

// Load sample Excel file containing slicer.
Workbook wb = new Workbook(dirPath + "sampleUpdatingSlicer.xlsx");
 
// Access first worksheet.
Worksheet ws = wb.getWorksheets().get(0);
 
// Access the first slicer inside the slicer collection.
Slicer slicer = ws.getSlicers().get(0);
 
// Access the slicer items.
SlicerCacheItemCollection scItems = slicer.getSlicerCache().getSlicerCacheItems();
 
// Unselect 2nd and 3rd slicer items.
scItems.get(1).setSelected(false);
scItems.get(2).setSelected(false);
 
// Refresh the slicer.
slicer.refresh();

// Set the slicer style/formatting.
slicer.setStyleType(SlicerStyleType.SLICER_STYLE_LIGHT_6);

// Remove slicer.
ws.getSlicers().remove(slicer);

Add Custom XML Parts and Select them by ID

Custom XML Parts are the XML data that is stored inside the Microsoft Excel documents and are used by the applications that deal with them. There is no direct way of adding them using Microsoft Excel UI at the moment. However, you can add them programmatically in various ways e.g. using VSTO, using Aspose.Cells etc. Please use Workbook.getCustomXmlParts().add() method if you want to add Custom XML Part using Aspose.Cells API. You can also set its ID, using the CustomXmlPart.ID property. Similarly, if you want to select Custom XML Part by ID, you can use Workbook.getCustomXmlParts().selectByID() method.

Get Address, CellCount Offset, EntireColumn and EntireRow of the Range

Aspose.Cells has added few new utility methods inside the Range object that help the user finding Address, Cell Count, Offset, Entire Column and Entire Row of the Range object. Please see the following article for more detail on this.

Extract Text from the Gear Type SmartArt Shape

Aspose.Cells can extract text from the Gear Type Smart Art Shape. In order to do so, you should first convert Smart Art Shape to Group Shape using the Shape.getResultOfSmartArt() method. Then you should get the array of all the Individual Shapes forming the Group Shape using the GroupShape.getGroupedShapes() method. Finally, you can iterate all of Individual Shapes one by one in a loop and extract their text using the Shape.getText() method.
