将CSV转换为JSON，使用C++

将CSV转换为JSON

Aspose.Cells支持将CSV转换为JSON。为此，API提供了ExportRangeToJsonOptions和JsonUtility类。ExportRangeToJsonOptions类提供导出范围至JSON的选项。ExportRangeToJsonOptions类具有以下属性：

• GetExportAsString()：导出单元格的字符串值给JSON。
• GetHasHeaderRow()：指示范围是否包含标题行。
• GetIndent()：指示缩进。

JsonUtility类使用ExportRangeToJsonOptions类设置的导出选项导出JSON。

以下代码示例演示了如何使用 ExportRangeToJsonOptions 和 JsonUtility 类加载 源 CSV 文件 并在控制台中打印 JSON 输出。

示例代码

#include <iostream>
#include "Aspose.Cells.h"
using namespace Aspose::Cells;

int main()
{
    Aspose::Cells::Startup();

    // Source directory
    U16String srcDir(u"..\\Data\\01_SourceDirectory\\");

    // Create load options for CSV format
    LoadOptions loadOptions(LoadFormat::Csv);

    // Load CSV file
    Workbook workbook(srcDir + u"SampleCsv.csv", loadOptions);

    // Get the last cell in the worksheet
    Cell lastCell = workbook.GetWorksheets().Get(0).GetCells().GetLastCell();

    // Set JsonSaveOptions
    JsonSaveOptions jsonSaveOptions;

    // Create a range from the first cell to the last cell
    Range range = workbook.GetWorksheets().Get(0).GetCells().CreateRange(0, 0, lastCell.GetRow() + 1, lastCell.GetColumn() + 1);

    // Export the range to JSON
    U16String data = JsonUtility::ExportRangeToJson(range, jsonSaveOptions);

    // Print JSON
    std::cout << data.ToUtf8() << std::endl;

    Aspose::Cells::Cleanup();
}
