Implementation Guide

Overview: Removing hyperlinks from shapes or charts can declutter your spreadsheets, making them more manageable.

Steps to Implement:

  1. Load Your Document Start by loading the Excel document using Watermarker with appropriate load options:

    import com.groupdocs.watermark.Watermarker;
import com.groupdocs.watermark.contents.SpreadsheetContent;
import com.groupdocs.watermark.options.SpreadsheetLoadOptions;

public class RemoveHyperlinks {
    public static void run() {
        SpreadsheetLoadOptions loadOptions = new SpreadsheetLoadOptions();
        Watermarker watermarker = new Watermarker("YOUR_DOCUMENT_DIRECTORY/spreadsheet.xlsx", loadOptions);

        // Your code continues here...
    }
}

  2. Access Content and Modify Hyperlinks Get the spreadsheet content to access specific shapes or charts:

    SpreadsheetContent content = watermarker.getContent(SpreadsheetContent.class);

// Remove hyperlinks from a chart in Worksheet 1
content.getWorksheets().get_Item(0).getCharts().get_Item(0).setHyperlink(null);

// Similarly, remove hyperlink from a shape in Worksheet 1
content.getWorksheets().get_Item(0).getShapes().get_Item(0).setHyperlink(null);

  3. Save and Close Once modifications are done, save your changes:

    watermarker.save("YOUR_OUTPUT_DIRECTORY/spreadsheet_modified.xlsx");
watermarker.close();

Overview: Replacing hyperlinks is useful for updating links to more current or relevant URLs.

Steps to Implement:

  1. Load Your Document Similar to removing, start by loading the document as shown above.

  2. Access Content and Update Hyperlinks Modify the hyperlinks as needed:

    // Replace hyperlink for a chart in Worksheet 0
content.getWorksheets().get_Item(0).getCharts().get_Item(0).setHyperlink("https://www.aspose.com/");

// Replace hyperlink for a shape in Worksheet 0
content.getWorksheets().get_Item(0).getShapes().get_Item(0).setHyperlink("https://www.groupdocs.com/");

  3. Save and Close Save the document with updated links:

    watermarker.save("YOUR_OUTPUT_DIRECTORY/spreadsheet_modified.xlsx");
watermarker.close();
