Aspose.Cells 支持将工作簿转换为 Json(JavaScript 对象表示法)文件。
将Excel工作簿转换为JSON
Aspose.Cells API 提供了将电子表格转换为 JSON 格式的支持。要导出工作簿到 JSON,请将 SaveFormat.Json 作为 Workbook.save(string, SaveFormat) 方法的第二个参数传递。你还可以使用 JsonSaveOptions 类来指定导出工作表到 JSON 的其他设置。
以下代码示例演示如何使用 SaveFormat.Json 枚举成员将活动工作表导出为 JSON。请参阅代码,将 source file 转换为 输出 JSON 文件。以作参考。
