Access and Update Portion of Rich Text in Excel using Java

Aspose.Cells for Java API provides easy to use a mechanism to access the format related properties of each character from a cell containing Rich Text. The API has exposed the getCharacters & setCharacters methods for the Cell class that allows to access & update the portion of the Rich Text in a cell. The Cell.getCharacters method returns an array of FontSetting objects where each object represents the styling of an individual character. The Cell.setCharacters method also accepts an array of FontSetting objects to set the styling for individual characters of a cell.

The following sample code explains the usage of Cell.getCharacters & Cell.setCharacters methods to access and manipulate the styling of Rich Text.

Aspose.Cells APIs are capable of converting all supported spreadsheet formats to HTML with the highest fidelity. The conversion process is efficient as well as configurable, that is; users can customize the HTML generation process as per their application requirement. Aspose.Cells APIs have exposed the HtmlSaveOptions class that is mainly responsible for the conversion process and provides a vast array of features to influence the HTML generation.

This release of Aspose.Cells for Java API has exposed an enumeration namely HtmlLinkTargetType along with a new property HtmlSaveOptions.LinkTargetType that together allows to set the target type for the links in spreadsheet while conversion to HTML format. The possible values of the HtmlLinkTargetType enumeration are as follow where the default value is SELF.

  • HtmlLinkTargetType.BLANK: Opens the linked document/page in a new window or tab.
  • HtmlLinkTargetType.PARENT: Opens the linked document/page in parent frame.
  • HtmlLinkTargetType.SELF: Opens the linked document/page in the same frame where the link was clinked.
  • HtmlLinkTargetType.TOP: Opens the linked document/page in the full body of the window.

Here is the simplest usage scenario of newly exposed APIs to set the link target type.

Detect If VbaProject is Signed

Aspose.Cells for Java 8.6.1 has exposed the VbaProject.isSigned property that can be used to test if a VbaProject in a Workbook is signed or not. Boolean type property returns true if the project is signed.

Following is the simple usage scenario.

//Load a spreadsheet
Workbook workbook = new Workbook(inputFilePath);

//Retrieve the VbaProject from the Workbook
VbaProject project = workbook.getVbaProject();

//Test if VbaProject is signed
if (project.isSigned())
    System.out.println("VBA Project is Signed");
	System.out.println("VBA Project is not Signed");
