可能的使用场景
可以使用Microsoft Excel将文本转换为列。此功能在数据工具下的数据标签中提供。为了将一列内容拆分为多列，数据中应包含特定分隔符（如逗号或其他字符），Microsoft Excel会根据此分隔符将单元格内容拆分成多个单元格。Aspose.Cells for JavaScript通过C++也提供了此功能。
使用Aspose.Cells for JavaScript通过C++将文本转换为列。
以下示例代码说明了 Cells.textToColumns(number, number, number, TxtLoadOptions) 方法的用法。代码首先在第一个工作表的 A 列添加一些人名。名和姓用空格字符分隔。然后对 A 列应用 Cells.textToColumns(number, number, number, TxtLoadOptions) 方法，并将结果保存为输出的 Excel 文件。如果你打开 输出 Excel 文件，会看到名字在 A 列，姓在 B 列，如截图所示。
