将JSON转换为CSV

Contents
[ ]

Aspose.Cells支持将简单和嵌套的JSON转换为CSV。为此,API提供了JsonLayoutOptionsJsonUtility类。JsonLayoutOptions类提供了JSON布局的选项,比如IgnoreArrayTitle(如果数组是对象的属性,则忽略标题)或者ArrayAsTable(将数组处理为表)。JsonUtility类使用与JsonLayoutOptions类设置的布局选项处理JSON。

以下代码示例演示了如何使用JsonLayoutOptionsJsonUtility类加载source JSON file并生成output CSV file

示例代码

// For complete examples and data files, please go to https://github.com/aspose-cells/Aspose.Cells-for-Java
//Source directory
String sourceDir = Utils.Get_SourceDirectory();
//Output directory
String outputDir = Utils.Get_OutputDirectory();
// Read JSON file
String str = new String(Files.readAllBytes(Paths.get(sourceDir + "SampleJson.json")));
// Create empty workbook
Workbook workbook = new Workbook();
// Get Cells
Cells cells = workbook.getWorksheets().get(0).getCells();
// Set JsonLayoutOptions
JsonLayoutOptions importOptions = new JsonLayoutOptions();
importOptions.setConvertNumericOrDate(true);
importOptions.setArrayAsTable(true);
importOptions.setIgnoreArrayTitle(true);
importOptions.setIgnoreObjectTitle(true);
JsonUtility.importData(str, cells, 0, 0, importOptions);
// Save Workbook
workbook.save(outputDir + "SampleJson_out.csv");
