This quick tutorial guides how to split merged cells in Excel using Node.js. It has the details to set the IDE for the development, a list of steps required for writing the application, and a sample code demonstrating how to unmerge cells in Excel using node.js. You can perform this operation on any of the platforms of your choice without installing any third-party tools for spreadsheets.

Steps to Unmerge Cells using Node.js

1. Set the IDE to use Aspose.Cells for Node.js via Java to unmerge cells
2. Load the source Excel file into the Workbook object for splitting the cells
3. Access the target sheet and create a range for the merged cells
4. Call the Range.unMerge() method to remove the merging
5. Save the output file

These steps summarize how to unmerge cells without losing data using Node.js. Commence the process by selecting the target sheet in the source Excel file and creating a range around the cells where you want to split the cells. Call the Range.unMerge() method to remove the splitting of the cells and place the existing data in the top-left cell of the removed range.

Code to Split Merged Cells using Node.js

This code shows how to unmerge cells in Excel. If you have a list of all the merged areas, create a range for each cell area and call the unMerge() method for deleting merged areas from the complete collection. For clearing the merged cells in the sheet, call the clearMergedCells() method which only deletes the contents of the merged cells.
