如何将 excel 文件转换/保存为 pdf？我正在使用 java play framework 生成一些 excel 文件，现在要求更改为 pdf。我不想重新编码一切。
有没有办法转换成pdf？
我生成的 excel 文件来自模板；我读取了 excel 模板文件，写入更改，然后另存为新的 excel 文件。这样，模板就不会改变。它包含边框、图像和其他格式。
最佳答案
您需要以下 Java 库和关联的 JAR 文件才能使程序运行。 兴趣点 v3.8 iText v5.3.4
试试这个例子将 XLS 转换为 PDF
接受 Excel 电子表格数据作为输入并将其转换为 PDF 表格数据的完整 Java 代码如下所示:
import java.io.FileInputStream;
import java.io.*;
import org.apache.poi.hssf.usermodel.HSSFWorkbook;
import org.apache.poi.hssf.usermodel.HSSFSheet;
import org.apache.poi.ss.usermodel.*;
import java.util.Iterator;
import com.itextpdf.text.*;
import com.itextpdf.text.pdf.*;
public class excel2pdf {
public static void main(String[] args) throws Exception{
FileInputStream input_document = new FileInputStream(new File("C:\\excel_to_pdf.xls"));
// Read workbook into HSSFWorkbook
HSSFWorkbook my_xls_workbook = new HSSFWorkbook(input_document);
// Read worksheet into HSSFSheet
HSSFSheet my_worksheet = my_xls_workbook.getSheetAt(0);
// To iterate over the rows
Iterator<Row> rowIterator = my_worksheet.iterator();
//We will create output PDF document objects at this point
Document iText_xls_2_pdf = new Document();
PdfWriter.getInstance(iText_xls_2_pdf, new FileOutputStream("Excel2PDF_Output.pdf"));
iText_xls_2_pdf.open();
//we have two columns in the Excel sheet, so we create a PDF table with two columns
//Note: There are ways to make this dynamic in nature, if you want to.
PdfPTable my_table = new PdfPTable(2);
//We will use the object below to dynamically add new data to the table
PdfPCell table_cell;
//Loop through rows.
while(rowIterator.hasNext()) {
Row row = rowIterator.next();
Iterator<Cell> cellIterator = row.cellIterator();
while(cellIterator.hasNext()) {
Cell cell = cellIterator.next(); //Fetch CELL
switch(cell.getCellType()) { //Identify CELL type
//you need to add more code here based on
//your requirement / transformations
case Cell.CELL_TYPE_STRING:
//Push the data from Excel to PDF Cell
table_cell=new PdfPCell(new Phrase(cell.getStringCellValue()));
//feel free to move the code below to suit to your needs
my_table.addCell(table_cell);
break;
}
//next line
}
}
//Finally add the table to PDF document
iText_xls_2_pdf.add(my_table);
iText_xls_2_pdf.close();
//we created our pdf file..
input_document.close(); //close xls
}
}
