Create Excel Workbook via .NET API

The Simplexcel library enables C# .NET programmers to generate an Excel spreadsheet inside their own .NET apps. You can easily create a workbook and add worksheets, assign a name to it with a couple of lines of .NET code. You can also populate its cells, and add them to a new Workbook with ease. It also supports setting font type and text size for a created sheet.

// using Simplexcel;
var sheet = new Worksheet("Hello, world!");
sheet.Cells[0, 0] = "Hello,";
sheet.Cells["B1"] = "World!";

var workbook = new Workbook();
workbook.Add(sheet);
workbook.Save(@"d:\test.xlsx");

Create Hyperlinks to an Excel Cell

The open source Simplexcel library has provided the capability to create hyperlinks inside an Excel worksheet cell with ease using C# .NET commands. You can easily set your desired format for the hyperlinks. Developers can easily set formatting like bold or font size or border for their worksheet cells.

// Just Two lines of code can do it

sheet.Cells["A1"] = "Click me now!";
sheet.Cells["A1"].Hyperlink = "https://github.com/mstum/Simplexcel/";

Add Page Setup Properties for a Worksheet

The open source Simplexcel library enables software developers to set and apply page setup properties for a Worksheet inside their own .NET applications. Page set-up settings affect the way the users see a worksheet. It controls the worksheet features like paper size, page orientation, page headers, and margins, and gridlines.

var sheet = new Worksheet("Hello, world!");
sheet.PageSetup.PrintRepeatRows = 2; // How many rows (starting with the top one)
sheet.PageSetup.PrintRepeatColumns = 0; // How many columns (starting with the left one, 0 is default)
sheet.PageSetup.Orientation = Orientation.Landscape;


sheet.Cells["A1"] = "Title!";
sheet.Cells["A1"].Bold = true;
sheet.Cells["A2"] = "Subtitle!";
sheet.Cells["A2"].Bold = true;
sheet.Cells["A2"].TextColor = Color.Magenta;
for (int i = 0; i < 100; i++)
{
    sheet.Cells[i + 2, 0] = "Entry Number " + (i + 1);
}

Freeze Panes in a worksheet

The open source Simplexcel library has provided the capability for freezing panes in a worksheet using a couple of C# .NET commands. Freeze panes are a very useful feature while working on multiple worksheets, You can keep an area of a worksheet visible while you scroll to another area of the worksheet. At the moment, it is being kept simple; you can either freeze the first row or the leftmost column (A) of a worksheet.

// Freeze the first row
Worksheet.FreezeTopRow 

// Freeze the leftmost column 
Worksheet.FreezeLeftColumn
