DsExcel Java enables users to render Excel cell ranges inside PDF.
This feature is useful especially when you're dealing with bulk data in the spreadsheets and you want to render only specific Excel range inside an existing PDF file. For instance - let's say you have a worksheet containing large amounts of sales data with fields such as "Number of Products Sold", "Area Sales Manager", "Region" etc. but you want to export only a chunk of useful data (like only "Number of Products Sold" and "Region") at some location in a PDF file and not all the data (you don't want to include the "Area Sales Manager" information). In this scenario, the "Render Excel Range Inside PDF" feature can be used to select some specific ranges in the worksheet and render them to specific location in a PDF file to generate full PDF reports.
In order to render Excel range inside the PDF file, you need to first create an instance of the PrintManager class and then use the draw() method to render the Excel range on a PDF page at a location. In case, you want to add some extra information in your PDF file (data which is not present in your Excel file), you can use the appendPage() method of the PrintManager class after configuring all the pagination settings. Finally, call the updatePageNumberAndPageSettings() method in order to update the indexes of the page number and the page settings for each page. When everything is done, simply save your PDF file using the savePageInfosToPDF() method.
Refer to the following example code to allow users to render Excel ranges inside the PDF file .
