Populate Data First by Row then by Column

Contents

Putting data in the sequence A1, B1, A2, B2 is faster than A1, A2, B1, B2. If there are many cells in a worksheet and you follow the second sequence, that is, you’re filling the data row by row, this tip can make the program much faster.

// The path to the documents directory.
string dataDir = RunExamples.GetDataDir(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);
// Create a workbook
Workbook workbook = new Workbook();
// Populate Data into Cells
Cells cells = workbook.Worksheets[0].Cells;
cells["A1"].PutValue("data1");
cells["B1"].PutValue("data2");
cells["A2"].PutValue("data3");
cells["B2"].PutValue("data4");
// Save workbook
workbook.Save(dataDir + "output_out.xlsx");
