Grouping rows and columns in Excel is a valuable feature that can simplify working with large or complex datasets. This feature enables you to hide or show individual sections of data for better viewing and analysis. For instance, if you have a worksheet with data for various regions or departments, you can group the rows for each region or department together. Once grouped, you can collapse or expand each group as required, which makes it easier for you to focus on specific parts of the data while keeping the rest of the worksheet unaffected. In this article, you will learn how to group or ungroup rows and columns, along with how to expand or collapse groups in Excel in C++ using Spire.XLS for C++.

Group Rows and Columns in Excel in C++

The XlsWorksheet->GroupByRows(int firstRow, int lastRow, bool isCollapsed) and XlsWorksheet->GroupByColumns (int firstColumn, int lastColumn, bool isCollapsed) methods in Spire.XLS for C++ can be used to group specific rows and columns in an Excel worksheet. The detailed steps are as follows:

• Initialize an instance of the Workbook class.
• Load an Excel file using the Workbook->LoadFromFile(LPCWSTR_S fileName) method.
• Get a specific worksheet by its index using the Workbook->GetWorksheets()->Get(int index) method.
• Group specific rows in the worksheet using the XlsWorksheet->GroupByRows(int firstRow, int lastRow, bool isCollapsed) method.
• Group specific columns in the worksheet using the XlsWorksheet->GroupByColumns (int firstColumn, int lastColumn, bool isCollapsed) method.
• Save the result file using the Workbook->SaveToFile (LPCWSTR_S fileName, ExcelVersion version) method.

#include "Spire.Xls.o.h";

using namespace Spire::Xls;


int main()
{
	//Initialize an instance of the Workbook class
	Workbook* workbook = new Workbook();

	//Load an Excel file
	workbook->LoadFromFile(L"Sample.xlsx");

	//Get the first worksheet
	Worksheet* sheet = workbook->GetWorksheets()->Get(0);

	//Group the 2nd, 3rd, 4th, 5th and 6th rows
	sheet->GroupByRows(2, 6, false);
	//Group the 3rd and 4th columns
	sheet->GroupByColumns(3, 4, false);

	//Save the result file
	workbook->SaveToFile(L"GroupRowsAndColumns.xlsx", ExcelVersion::Version2013);
	workbook->Dispose();
	delete workbook;
}
