How to Merge Cells in Excel Without Losing Data

This article demonstrates how to merge multiple cells into one using Microsoft Excel and IronXL programmatically.

Merge Multiple Cells into a single cell using Microsoft Excel

The built-in Merge and Center option in Excel is the quickest and simplest approach to integrate two or more cells. There are only 2 fast steps in the entire process:

• Choose the adjacent Excel cells that you want to combine into one cell.
• Click the Merge & Center button in the Home tab's Alignment group to merge two cells or multiple columns in Excel.

In this example, upper left cell A1 contains a list of fruits, and data in two adjacent empty cells (B1 and C1) is combined to create a single, sizable cell that can hold the complete list.

Merging Cells

The text is centered, and the selected cells are combined into one large cell once you click Merge and Center, as shown in the above screenshot.

Excel's options to combine multiple cells

Select the choice you want from the drop-down menu by clicking the tiny drop-down arrow next to the Merge & Center button, which will give you access to a few more merging options supplied by Excel such as Merge Across, Unmerge Cells.

Combine Cells

Using the Merge Across command, each row's individually chosen cells are combined.

Using the Merge Cells command, you can combine the selected cells into one without centering the text and without losing data.

Simply pick the merged cell and click the desired alignment in the Alignment group on the Home page to change the text alignment of only the data after merging all the cells.

There are a few things to remember when utilizing Excel's built-in functions to combine adjacent cells:

• Because only the content of the upper-left cell will remain after merging, all data in the other cells will be removed. Therefore, make sure that all the data you want to include in a merged cell is entered in the leftmost cell of the chosen range.
• The selected cells are likely in Edit mode if the Merge and Center button is grayed out. Try merging cells after exiting Edit mode by pressing the Enter key.

Merge Cell using IronXL

IronXL can merge multiple columns/cells in the existing Excel sheets. Below is the sample code to merge multiple cells.

var excelDoc = IronXL.WorkBook.LoadExcel("demo.xlsx");
WorkSheet workSheet = excelDoc.DefaultWorkSheet;
var range = workSheet["A1:C1"];
workSheet.Merge(range.RangeAddressAsString);
excelDoc.Save();

var excelDoc = IronXL.WorkBook.LoadExcel("demo.xlsx");
WorkSheet workSheet = excelDoc.DefaultWorkSheet;
var range = workSheet["A1:C1"];
workSheet.Merge(range.RangeAddressAsString);
excelDoc.Save();

Dim excelDoc = IronXL.WorkBook.LoadExcel("demo.xlsx")
Dim workSheet As WorkSheet = excelDoc.DefaultWorkSheet
Dim range = workSheet("A1:C1")
workSheet.Merge(range.RangeAddressAsString)
excelDoc.Save()

In the above example code, first, the existing Excel workbook is loaded into the IronXL workbook object and set as the default worksheet. In the next step, select the worksheet range as the input for the Merge function available in the worksheet, IronXL will combine multiple cells in Excel. After that, the Save function is used to save the Excel again.

A group of cells can be merged with Merge. Only the first column's and row's values of the merged region's cells will be displayed; the merging operation will not remove any value or data from the other cells. In IronXL, the value of those merged cells is still available.
