使用Aspose.Cells，您可以将CSV文件转换为Excel、OpenOffice、Pdf、Json和许多其他不同的格式。
打开 CSV 文件
逗号分隔值（CSV）文件包含记录，其中值由逗号分隔。 数据存储为表格，其中每列由逗号字符分隔并由双引号字符引用。 如果字段值包含双引号字符，则用一对双引号字符进行转义。 您还可以使用 Microsoft Excel 将电子表格数据导出到 CSV。

打开 CSV 文件并替换无效字符
在 Excel 中，打开具有特殊字符的 CSV 文件时，字符会自动替换。 Aspose.Cells API 也采用相同的方法，示例如下所示的代码示例。

打开制表符分隔文件
制表符分隔（文本）文件包含电子表格数据，但没有任何格式。数据按行和列排列，就像在表格和电子表格中一样。基本上，制表符分隔文件是一种带有每个列之间制表符的特殊类型的纯文本文件。

打开制表符分隔数值（TSV）文件
制表符分隔数值（TSV）文件包含电子表格数据，但没有任何格式。它与制表符分隔文件相同，其中数据按行和列排列，就像在表格和电子表格中一样。
