The excel export allows exporting DataGrid data to Excel document. You need to use the
ExcelExport method for exporting. To enable Excel export in the datagrid, set the AllowExcelExport property as true.

}The excel export provides an option to customize mapping of the datagrid to excel document.
The excel export provides an option to export the current page into excel. To export current page, define exportType to CurrentPage.

}The excel export provides an option to include theme for exported excel document.
To apply theme in exported Excel, define the theme in export properties.

}By default, material theme is applied to exported excel document.
You can assign the file name for the exported document by defining fileName property in excel export properties.

}The excel export provides outline option for grouped records which hides the detailed data for better viewing. In datagrid, we have provided the outline option for the exported document when the data’s are grouped.
@using Syncfusion.Blazor.Grids
<SfGrid ID="Grid" @ref="DefaultGrid" DataSource="@Orders" AllowGrouping="true" Toolbar="@(new List<string>() { "ExcelExport" })" AllowExcelExport="true" AllowPaging="true">

</SfGrid>
@code{

public List<Order> Orders { get; set; }
public async Task ToolbarClickHandler(Syncfusion.Blazor.Navigations.ClickEventArgs args)

await this.DefaultGrid.ExcelExport();

}
protected override void OnInitialized()

OrderID = 1000 + x,
CustomerID = (new string[] { "ALFKI", "ANANTR", "ANTON", "BLONP", "BOLID" })[new Random().Next(5)],
Freight = 2.1 * x,
OrderDate = DateTime.Now.AddDays(-x),

}
public class Order
{
public int? OrderID { get; set; }
public string CustomerID { get; set; }
public DateTime? OrderDate { get; set; }
public double? Freight { get; set; }
}
}Microsoft Excel permits up to seven nested levels in outlines. So that in the datagrid we can able to provide only up to seven nested levels and if it exceeds more than seven levels then the document will be exported without outline option. Please refer the Microsoft Limitation
You can export the Excel grid with specific columns instead of all columns which are defined in the Grid definition. To achieve this scenario by using Columns property of the ExcelExportProperties class.

}Excel export provides an option to define the datasource dynamically before exporting. To export data dynamically, define it in the DataSource property of the ExcelExportProperties class.
The following sample code demonstrates dynamically modifying the data source before exporting it,
@using Syncfusion.Blazor.Grids
<SfGrid ID="Grid" @ref="DefaultGrid" DataSource="@Orders" AllowExcelExport="true" AllowPaging="true" Toolbar="@(new List<string>() { "ExcelExport" })">
<GridEvents OnToolbarClick="OnToolbarClick" TValue="Order"></GridEvents>

<GridColumn Field=@nameof(Order.OrderID) HeaderText="Order ID" TextAlign="TextAlign.Right" Width="120"></GridColumn>
<GridColumn Field=@nameof(Order.CustomerID) HeaderText="Customer Name" Width="150"></GridColumn>
<GridColumn Field=@nameof(Order.OrderDate) HeaderText=" Order Date" Format="d" Type="ColumnType.Date" TextAlign="TextAlign.Right" Width="130"></GridColumn>
<GridColumn Field=@nameof(Order.Freight) HeaderText="Freight" Format="C2" TextAlign="TextAlign.Right" Width="120"></GridColumn>
</GridColumns>
</SfGrid>
@code{
private SfGrid<Order> DefaultGrid;
public List<Order> Orders { get; set; }
public async Task OnToolbarClick(Syncfusion.Blazor.Navigations.ClickEventArgs args)
{
if (args.Item.Id == "Grid_excelexport") //Id is combination of Grid's ID and itemname
{
ExcelExportProperties ExcelProperties = new ExcelExportProperties();
ExcelProperties.DataSource = Orders;
await this.DefaultGrid.ExcelExport(ExcelProperties);
}
}
protected override void OnInitialized()
{
Orders = Enumerable.Range(1, 15).Select(x => new Order()
{
OrderID = 1000 + x,
CustomerID = (new string[] { "ALFKI", "ANANTR", "ANTON", "BLONP", "BOLID" })[new Random().Next(5)],
ShipCountry = (new string[] { "Germany", "UK", "USA", "Italy", "France" })[new Random().Next(5)],
Freight = 2.1 * x,
OrderDate = DateTime.Now.AddDays(-x),
}).ToList();
}
public class Order
{
public int? OrderID { get; set; }
public string CustomerID { get; set; }
public string ShipCountry { get; set; }
public DateTime? OrderDate { get; set; }
public double? Freight { get; set; }
}
}Excel export provides an option to define the columns dynamically before exporting. You can define the dynamic columns using Columns property of the ExcelExportProperties class.
The following sample code demonstrates dynamically adding ShipCountry column in the exported excel file,
@using Syncfusion.Blazor.Grids
<SfGrid ID="Grid" @ref="DefaultGrid" DataSource="@Orders" AllowExcelExport="true" AllowPaging="true" Toolbar="@(new List<string>() { "ExcelExport" })">

<GridColumn Field=@nameof(Order.Freight) HeaderText="Freight" Format="C2" TextAlign="TextAlign.Right" Width="120"></GridColumn>
</GridColumns>
</SfGrid>

{
ExcelExportProperties ExportProperties = new ExcelExportProperties();
var columns = await DefaultGrid.GetColumns(); //get the columns available in Grid
columns.Add(new GridColumn() { Field = "ShipCountry" }); //adding additional column
ExportProperties.Columns = columns;
await DefaultGrid.ExcelExport(ExportProperties);
}
}
protected override void OnInitialized()
{

{

CustomerID = (new string[] { "ALFKI", "ANANTR", "ANTON", "BLONP", "BOLID" })[new Random().Next(5)],
ShipCountry = (new string[] { "Germany", "UK", "USA", "Italy", "France" })[new Random().Next(5)],
Freight = 2.1 * x,
OrderDate = DateTime.Now.AddDays(-x),
}).ToList();
}
public class Order
{
public int? OrderID { get; set; }
public string CustomerID { get; set; }
public string ShipCountry { get; set; }
public DateTime? OrderDate { get; set; }
public double? Freight { get; set; }
}
