Convert Text to Columns using Aspose.Cells for JavaScript via C++
Possible Usage Scenarios
You can convert text to columns using Microsoft Excel. This feature is available from Data Tools under the Data tab. In order to split the contents of a column into multiple columns, the data should contain a specific delimiter such as a comma (or any other character) based on which Microsoft Excel splits the contents of a cell into multiple cells. Aspose.Cells for JavaScript via C++ also provides this feature via Cells.textToColumns(number, number, number, TxtLoadOptions).
Convert Text to Columns using Aspose.Cells for JavaScript via C++
The following sample code explains the usage of Cells.textToColumns(number, number, number, TxtLoadOptions) method. The code first adds some people’s names in column A of the first worksheet. The first and last names are separated by a space character. Then it applies the Cells.textToColumns(number, number, number, TxtLoadOptions) method on column A and saves it as an output Excel file. If you open the output Excel file, you will see that first names are in column A while last names are in column B as shown in this screenshot.
