使用 aspose 库在 Java 中将 Excel 文件另存为 Word

Question

我有一个 excel 文件，我想在 java 中保存为 Document (word)，我尝试使用 Aspose 库，我没有找到从 excel 转换为 word 的方法，所以我将 excel 文件转换为 pdf然后从pdf到word。

这就是我所做的：

       import com.aspose.cells.PdfSaveOptions;
       import com.aspose.cells.SaveFormat;
       import com.aspose.cells.Workbook;
       import com.aspose.pdf.Document;

         .....

      Workbook workbook1 = new Workbook("file.xlsx");

      // Create PDF options
      PdfSaveOptions options = new PdfSaveOptions();
      options.setOnePagePerSheet(true);

      // Save the document in PDF format
      workbook1.save("file1.pdf", options);

第一个问题我得到带有红色签名的pdf文件，如何删除它？

之后我将pdf转换为word：

      Document pdfDocument = new Document("file1.pdf");
        //Save the file into MS document format
      pdfDocument.save("file2.docx", SaveFormat.DOCX);
     

问题是 doc 文件完全是空的，我得到一个异常：

此处指定的行 (RcController.java:333) ->

  pdfDocument.save("file2.docx", SaveFormat.DOCX); 

有什么想法吗？还是有其他库可以用来直接从 excel 转换为 doc？

Answer 1

Aspose.Cells 在较新版本（例如 Aspose.Cells for Java v21.9）中引入了新的Excel to DOCX 功能，可以直接将 Excel 电子表格转换为 DOCX（不使用中间 PDF）。因此，如果您的文件不复杂，您可以尝试一下。请参阅您可以尝试的示例代码： 例如

示例代码：

Workbook workbook = new Workbook("f:\\files\\ExcelFile.xlsx");
workbook.save("f:\\files\\out1.docx", SaveFormat.DOCX);

如果您的文件没有通过直接方法正确转换为 DOCX，请分享您输入的 Excel 文件。我们会尽快检查您的问题。此外，对于复杂的 Excel 文件，您仍然可以使用现有的方法，即通过 Aspose.Cells for Java 将 Excel 转为 PDF，然后通过 Aspose.PDF 将 PDF 转为 DOCX。我们还建议您在专用的forums 上使用资源文件发布您的问题（以防您无法使用最新版本的 API 解决问题），我们可以准确地解决您的问题。
