Today, in this article we shall cover simple use cases where we will be connecting the SQL server then we will Export Dataset To Excel file C# .NET examples.

In our last post, we saw the usage of OpenXML SDK (open source SDK from Microsoft) to work with Office Word, Excel, and PowerPoint. We looked at the basic read and write of an excel file using C# in .NET or .NET Core.

Today in this article, we will cover below aspects,

Getting Started
Connecting SQL Server

Getting Started

Let’s create a .NET Core project, you can choose any project template. Here we shall use the .NET Core 3.1 Console project.

Please install latest available OpenXML Nuget package,

PM> Install-Package Open-XML-SDK -Version 2.11.3

Please install package from Nuget Package Manager,

Connecting SQL Server

Let’s now connect the SQL server and get the data filled as DataSet.

I have already discussed how to connect to the SQL server using SQLClient or EFCore in the below article.

Connect SQL Server ADO.NET C# Example

Getting Started with EFCore in ASP.NET Core

Please use below method which takes Dataset as input and save the each table as separate sheet in the excel sheet.

   public static void SaveDataSetAsExcel(DataSet dataset, string excelFilePath)
        {
            using (SpreadsheetDocument document = SpreadsheetDocument.Create(excelFilePath, SpreadsheetDocumentType.Workbook))
            {
                WorkbookPart workbookPart = document.AddWorkbookPart();
                workbookPart.Workbook = new Workbook();
                Sheets sheets = workbookPart.Workbook.AppendChild(new Sheets());

                foreach (DataTable table in dataset.Tables)
                {
                    UInt32Value sheetCount = 0;
                    sheetCount++;

                    WorksheetPart worksheetPart = workbookPart.AddNewPart<WorksheetPart>();

                    var sheetData = new SheetData();
                    worksheetPart.Worksheet = new Worksheet(sheetData);

                    Sheet sheet = new Sheet() { Id = workbookPart.GetIdOfPart(worksheetPart), SheetId = sheetCount, Name = table.TableName };
                    sheets.AppendChild(sheet);

                    Row headerRow = new Row();

                    List<string> columns = new List<string>();
                    foreach (System.Data.DataColumn column in table.Columns)
                    {
                        columns.Add(column.ColumnName);

                        Cell cell = new Cell();
                        cell.DataType = CellValues.String;
                        cell.CellValue = new CellValue(column.ColumnName);
                        headerRow.AppendChild(cell);
                    }

                    sheetData.AppendChild(headerRow);

                    foreach (DataRow dsrow in table.Rows)
                    {
                        Row newRow = new Row();
                        foreach (String col in columns)
                        {
                            Cell cell = new Cell();
                            cell.DataType = CellValues.String;
                            cell.CellValue = new CellValue(dsrow[col].ToString());
                            newRow.AppendChild(cell);
                        }

                        sheetData.AppendChild(newRow);
                    }



                }
                workbookPart.Workbook.Save();
        }

Finally, you shall see all the tables in the Dataset are saved as different tabs in the excel file.

In the above code, we are creating each sheet as a table name and its data.

The following examples shows how you can export a DataTable object to an Excel sheet or a DataSet object to an Excel file in C# and VB.NET.

GemBox.Spreadsheet uses the same API for all spreadsheet file formats (XLS, XLSX, ODS, CSV), so you can use the same code for filling customer files or your templates of various file formats with different data sources, such as DataTable or DataSet.

Export DataTable to Excel sheet

To insert a DataTable in an Excel sheet simply call the InsertDataTable method. You can use the InsertDataTableOptions to set various options for exporting data from DataTable to ExcelWorksheet such as:

ColumnHeaders — Defines whether to insert column headers.
StartRow and StartColumn — Define the position where to insert DataTable.
DataTableCellToExcelCellConverting — An event that fires when converting a DataTable cell value to an ExcelCell value which you can use to apply settings such as cell style.

Try exporting a DataTable online

You can test inserting a DataTable to an empty file with the interactive example below. Just choose an output file format, click Run Example, and download the generated file.

The example creates a DataTable, fills it with data, inserts it into an Excel file and saves The Excel file to a file format of your choice. After clicking on Run example, the C#/VB.NET code will be compiled and executed with only .NET framework and the GemBox.Spreadsheet component.

        var workbook = new ExcelFile();
        var worksheet = workbook.Worksheets.Add("DataTable to Sheet");

        var dataTable = new DataTable();

        dataTable.Columns.Add("ID", typeof(int));
        dataTable.Columns.Add("FirstName", typeof(string));
        dataTable.Columns.Add("LastName", typeof(string));

        dataTable.Rows.Add(new object[] { 100, "John", "Doe" });
        dataTable.Rows.Add(new object[] { 101, "Fred", "Nurk" });
        dataTable.Rows.Add(new object[] { 103, "Hans", "Meier" });
        dataTable.Rows.Add(new object[] { 104, "Ivan", "Horvat" });

Export DataTable performance

Since GemBox.Spreadsheet is completely written in C# and uses caching techniques, it offers both speed and memory optimizations. Your users will not need to wait for their reports to be generated any more. With GemBox.Spreadsheet you can read and write 1,000,000 rows with less than 256MB RAM and less than 4 seconds. You can try the performance yourself with the Performance example.

Export DataSet to Excel file

The following example shows how you can export a DataSet object to an Excel file in C# or VB.NET.

The process is similar to exporting a DataTable to a sheet. The only difference is that you need to iterate through every DataTable in a DataSet and for each DataTable you should first create an empty sheet, and after that you should insert the DataTable into the sheet.

Try exporting DataSet online

You can test inserting a DataSet to an empty file with the interactive example below. Just choose an output file format, click Run Example, and download the generated file.

The example creates a DataSet, fills it with data, inserts it into an Excel file and saves The Excel file to a file format of your choice. After clicking on Run example, the C#/VB.NET code will be compiled and executed with only .NET framework and the GemBox.Spreadsheet component.

        DataSet dataSet = new DataSet();
        for (int i = 0; i < 5; i++)
        {
            DataTable dataTable = new DataTable("Table " + (i + 1));
            dataTable.Columns.Add("ID", typeof(int));
            dataTable.Columns.Add("FirstName", typeof(string));
            dataTable.Columns.Add("LastName", typeof(string));

            dataTable.Rows.Add(new object[] { 100, "John", "Doe" });
            dataTable.Rows.Add(new object[] { 101, "Fred", "Nurk" });
