Question

我们希望数据占位符在excel中。我们以json格式输入数据。我们如何使用aspose.cell在运行时在提供的xlsx中将数据映射到占位符并生成excel输出？

有没有办法为pdf定义模板，可以从json加载数据？

使用aspose的转换例程在几行代码中将json转换为xls格式和pdf格式。即

创建工作簿
将数据映射到工作簿

是否有一个样本我可以在xlsx和pdf中引用aspose占位符？

我们担心，您无法直接将数据从JSON放到Aspose.Cells Workbook中。您必须先从JSON创建数据表或数组列表，然后才能根据需要使用智能标记功能。您将在Excel文件中指定一些标签，它将被称为模板Excel文件或Designer Excel文件。然后，您将从各种数据源将数据导入其中，例如列表或数据表等。

除此之外，您还可以使用Aspose.Cells API将数据导入工作表或从工作表中导出数据。

最后，您可以将工作簿或Excel文件保存为Pdf格式。

请参阅在线Aspose.Cells文档中的这些文档，以获取更多帮助和示例代码。

以下智能标记说明了如何使用重复动态公式

&=&=Sum(E{r}:F{r})

整个智能标记如下

Country Age1    Age2    Repeat Dynamic Formula
&=Person.Country(group:merge,skip:2)    &=Person.Age    &=Person.Age    &=&=Sum(E{r}:F{r})

请参阅以下屏幕截图。它显示包含智能标记的模板Excel文件和输出Excel文件以及单击显示公式时的输出Excel。

关于Aspose.PDF API，一旦将JSON数据转换为数据表或数组列表，就可以将文本添加到PDF文档中的任何占位符。您可以使用下面的代码段在PDF页面上添加文字。

// Open document
Document pdfDocument = new Document(dataDir + "input.pdf");

// Get particular page
Page pdfPage = (Page)pdfDocument.Pages[1];

// Create text fragment
TextFragment textFragment = new TextFragment("main text");
textFragment.Position = new Position(100, 600);

// Set text properties
textFragment.TextState.FontSize = 12;
textFragment.TextState.Font = FontRepository.FindFont("TimesNewRoman");
textFragment.TextState.BackgroundColor = Aspose.Pdf.Color.FromRgb(System.Drawing.Color.LightGray);
textFragment.TextState.ForegroundColor = Aspose.Pdf.Color.FromRgb(System.Drawing.Color.Red);

// Create TextBuilder object
TextBuilder textBuilder = new TextBuilder(pdfPage);

// Append the text fragment to the PDF page
textBuilder.AppendText(textFragment);

dataDir = dataDir + "AddText_out.pdf";

// Save resulting PDF document.
pdfDocument.Save(dataDir);
