Introduction
In this article, we will be discussing how to convert Excel to PDF using Java. Excel is a widely used spreadsheet application, while PDF is a popular format for sharing documents. Converting an Excel file to PDF is often required to ensure that the document remains the same across different devices and platforms.
Why convert Excel to PDF?
Excel files are often used for creating financial statements, invoices, and other important documents. However, these files can be easily edited by anyone who has access to them. Converting an Excel file to PDF ensures that the document remains intact and cannot be edited. PDFs are also easier to share and can be opened on any device or platform.
Using Java to convert Excel to PDF
Java is a popular programming language that can be used to convert Excel files to PDF. There are various libraries available in Java that can be used for this purpose, such as Apache POI and iText. In this article, we will be using Apache POI to convert Excel to PDF.
Step 1: Add Apache POI dependency to your project
To use Apache POI, you need to add its dependency to your project. You can do this by adding the following code to your pom.xml file: “`xml
Step 2: Read Excel file using Apache POI
Once you have added the dependency, you can start reading the Excel file using Apache POI. You can do this by creating an instance of the XSSFWorkbook class, which represents the Excel workbook. “`java FileInputStream file = new FileInputStream(new File(“path/to/excel/file.xlsx”)); XSSFWorkbook workbook = new XSSFWorkbook(file); “`
Step 3: Convert Excel to PDF using Apache POI
Once you have read the Excel file, you can convert it to PDF using Apache POI. You can do this by creating an instance of the PdfDocument class, which represents the PDF document. “`java PdfDocument pdfDoc = new PdfDocument(new PdfWriter(new FileOutputStream(“path/to/pdf/file.pdf”))); Document doc = new Document(pdfDoc); PdfPTable table = new PdfPTable(3); for (int i = 0; i < workbook.getNumberOfSheets(); i++) { XSSFSheet sheet = workbook.getSheetAt(i); for (int j = 0; j < sheet.getPhysicalNumberOfRows(); j++) { XSSFRow row = sheet.getRow(j); for (int k = 0; k < row.getPhysicalNumberOfCells(); k++) { XSSFCell cell = row.getCell(k); table.addCell(cell.toString()); } } } doc.add(table); doc.close(); ```
