Getting Started

After the reference to library was added to your project you are now ready to start writing code to create and edit Excel documents in your .NET application. You can copy the C# code lines from the section below to create an Excel document and save it to a memory buffer for further processing, to an Excel file or send it to browser for download in ASP.NET applications.

C# Code Samples

At the top of your C# source file add the using Winnovative.ExcelLib; statement to make available the Winnovative Excel Library API for your .NET application.

// add this using statement at the top of your C# file
using Winnovative.ExcelLib;

To create an Excel workbook and save it in an Excel file you can use the C# code below.

// Create an Excel 2007 (.xlsx) workbook
ExcelWorkbookFormat workbookFormat = ExcelWorkbookFormat.Xlsx_2007;

// use the code below instead to create an Excel 97-2003 (.xls) workbook
//ExcelWorkbookFormat workbookFormat = ExcelWorkbookFormat.Xls_2003;

// create the workbook in the desired format with a single worksheet
ExcelWorkbook workbook = new ExcelWorkbook(workbookFormat);

// get the first worksheet in the workbook
ExcelWorksheet worksheet = workbook.Worksheets[0];

// add a style to workbook
ExcelCellStyle helloWorldStyle = workbook.Styles.AddStyle("HelloWorldStyle");
helloWorldStyle.Alignment.HorizontalAlignment = ExcelCellHorizontalAlignmentType.Left;
helloWorldStyle.Alignment.VerticalAlignment = ExcelCellVerticalAlignmentType.Center;
helloWorldStyle.Font.Size = 14;
helloWorldStyle.Font.Bold = true;

// add a text to worksheet using the created style
worksheet["A1"].Text = "Hello World from Winnovative !!!";
worksheet["A1"].Style = helloWorldStyle;
worksheet["A1"].Style.Font.Color = Color.Blue;
worksheet["A1"].RowHeightInPoints = 19.5;

// autofit the Hello World text column
worksheet.AutofitColumn(1);

if (workbookFormat == ExcelWorkbookFormat.Xlsx_2007)
{
    // the workbook is saved in Excel 2007 (.xlsx) format
    workbook.Save("GettingStarted.xlsx");
}
else if (workbookFormat == ExcelWorkbookFormat.Xls_2003)
{
    // the workbook is saved in Excel 97-2003 (.xls) format 
    workbook.Save("GettingStarted.xls");
}

// close the workbook
workbook.Close();

To create an Excel workbook and save it in a memory buffer and then save it to a file you can use the C# code below.

// Create an Excel 2007 (.xlsx) workbook
ExcelWorkbookFormat workbookFormat = ExcelWorkbookFormat.Xlsx_2007;

// use the code below instead to create an Excel 97-2003 (.xls) workbook
//ExcelWorkbookFormat workbookFormat = ExcelWorkbookFormat.Xls_2003;

// create the workbook in the desired format with a single worksheet
ExcelWorkbook workbook = new ExcelWorkbook(workbookFormat);

// get the first worksheet in the workbook
ExcelWorksheet worksheet = workbook.Worksheets[0];

// add a style to workbook
ExcelCellStyle helloWorldStyle = workbook.Styles.AddStyle("HelloWorldStyle");
helloWorldStyle.Alignment.HorizontalAlignment = ExcelCellHorizontalAlignmentType.Left;
helloWorldStyle.Alignment.VerticalAlignment = ExcelCellVerticalAlignmentType.Center;
helloWorldStyle.Font.Size = 14;
helloWorldStyle.Font.Bold = true;

// add a text to worksheet using the created style
worksheet["A1"].Text = "Hello World from Winnovative !!!";
worksheet["A1"].Style = helloWorldStyle;
worksheet["A1"].Style.Font.Color = Color.Blue;
worksheet["A1"].RowHeightInPoints = 19.5;

// autofit the Hello World text column
worksheet.AutofitColumn(1);

// save the workbook in a memory buffer
byte[] excelDocumentBuffer = workbook.Save();

// close the workbook
workbook.Close();

if (workbookFormat == ExcelWorkbookFormat.Xlsx_2007)
{
    // save the memory buffer in an Excel 2007 (.xlsx) format file
    System.IO.File.WriteAllBytes("GettingStarted.xlsx", excelDocumentBuffer);
}
else if (workbookFormat == ExcelWorkbookFormat.Xls_2003)
{
    // save the memory buffer in Excel 97-2003 (.xls) format file
    System.IO.File.WriteAllBytes("GettingStarted.xls", excelDocumentBuffer);
}

To create in your ASP.NET MVC applications an Excel document in a memory buffer and then send it for download to browser you can use the C# code below.

// use the code below instead to create an Excel 97-2003 (.xls) workbook
//ExcelWorkbookFormat workbookFormat = ExcelWorkbookFormat.Xls_2003;

// create the workbook in the desired format with a single worksheet

    fileResult = new FileContentResult(excelDocumentBuffer,
        "Application/vnd.openxmlformats-officedocument.spreadsheetml.sheet");
    fileResult.FileDownloadName = "GettingStarted.xlsx";
}
else if (workbookFormat == ExcelWorkbookFormat.Xls_2003)

        "Application/x-msexcel");
    fileResult.FileDownloadName = "GettingStarted.xls";
}

return fileResult;
