Add PDF Bookmarks with Named Destinations using Node.js via C++

Possible Usage Scenarios

Named Destinations are special kinds of bookmarks or links in PDF that do not depend on PDF pages. It means, if pages are added or deleted from PDF, bookmarks may become invalid but named destinations will remain intact. To create Named Destination, please set the PdfBookmarkEntry.getDestinationName() property.

Add PDF Bookmarks with Named Destinations

Please see the following sample code, its source Excel file, and its output PDF file. The screenshot shows the bookmarks and named destinations inside the output PDF. The screenshot also describes how to view Named Destinations and that you need Professional version of Acrobat Reader.

Sample Code

const path = require("path");
const AsposeCells = require("aspose.cells.node");

// Load source Excel file
const dataDir = path.join(__dirname, "data");
const workbook = new AsposeCells.Workbook(path.join(dataDir, "samplePdfBookmarkEntry_DestinationName.xlsx"));

// Access first worksheet
const worksheet = workbook.getWorksheets().get(0);

// Access cell C5
let cell = worksheet.getCells().get("C5");

// Create Bookmark and Destination for this cell
const bookmarkEntry = new AsposeCells.PdfBookmarkEntry();
bookmarkEntry.setText("Text");
bookmarkEntry.setDestination(cell);
bookmarkEntry.setDestinationName("AsposeCells--" + cell.getName());

// Access cell G56
cell = worksheet.getCells().get("G56");

// Create Sub-Bookmark and Destination for this cell
const subbookmarkEntry1 = new AsposeCells.PdfBookmarkEntry();
subbookmarkEntry1.setText("Text1");
subbookmarkEntry1.setDestination(cell);
subbookmarkEntry1.setDestinationName("AsposeCells--" + cell.getName());

// Access cell L4
cell = worksheet.getCells().get("L4");

// Create Sub-Bookmark and Destination for this cell
const subbookmarkEntry2 = new AsposeCells.PdfBookmarkEntry();
subbookmarkEntry2.setText("Text2");
subbookmarkEntry2.setDestination(cell);
subbookmarkEntry2.setDestinationName("AsposeCells--" + cell.getName());

// Add Sub-Bookmarks in list
const list = [];
list.push(subbookmarkEntry1);
list.push(subbookmarkEntry2);

// Assign Sub-Bookmarks list to Bookmark Sub-Entry
bookmarkEntry.getSubEntries = function() {
return this.subEntries || (this.subEntries = []);
};
bookmarkEntry.getSubEntries().push(...list);

// Create PdfSaveOptions and assign Bookmark to it
const opts = new AsposeCells.PdfSaveOptions();
opts.setBookmark(bookmarkEntry);

// Save the workbook in Pdf format with given pdf save options
workbook.save(path.join(dataDir, "outputPdfBookmarkEntry_DestinationName.pdf"), opts);
