Detect Merged Cells in a Worksheet

Contents
[ ]

The component provides the Cells.GetMergedAreas() method which can get all merged cells. The following code sample shows you how to detect merged cells in a worksheet.

// For complete examples and data files, please go to https://github.com/aspose-cells/Aspose.Cells-for-.NET
// The path to the documents directory.
string dataDir = RunExamples.GetDataDir(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);
// Instantiate a new Workbook
// Open an existing excel file
Workbook wkBook = new Workbook(dataDir + "SampleInput.xlsx");
// Get a worksheet in the workbook
Worksheet wkSheet = wkBook.Worksheets["Sheet2"];
// Clear its contents
wkSheet.Cells.Clear();
// Get merged areas
CellArea[] areas = wkSheet.Cells.GetMergedAreas();
// Define some variables
int frow, fcol, erow, ecol, trows, tcols;
// Loop through the arraylist and get each cellarea
// To unmerge it
for (int i = 0; i < areas.Length; i++)
{
frow = areas[i].StartRow;
fcol = areas[i].StartColumn;
erow = areas[i].EndRow;
ecol = areas[i].EndColumn;
trows = erow - frow + 1;
tcols = ecol - fcol + 1;
wkSheet.Cells.UnMerge(frow, fcol, trows, tcols);
}
dataDir = dataDir + "MergeTrial.out.xlsx";
// Save the excel file
wkBook.Save(dataDir);
