Create Excel files in Xamarin

GemBox.Spreadsheet is a standalone .NET component with cross-platform support. You can use it on non-Windows platforms like Xamarin and Mono, enabling you to run it on Android and iOS mobile devices.

With GemBox.Spreadsheet you can process your workbooks (read, write, convert, and edit Excel files) from the native mobile apps.

The following example shows how you can create an Excel file in Xamarin.Forms mobile application using GemBox.Spreadsheet.

<ContentPage xmlns=""

    <StackLayout Padding="50" 
                 Spacing="20" >

        <Label Text="GemBox.Spreadsheet Example"
               Margin="0,0,0,30" />

        <TableView x:Name="table"
                   Intent="Data" >
                    <EntryCell Label="A1"
                               Text="Joe Doe" />

                    <EntryCell Label="A2"
                               Text="Fred Nurk" />

                    <EntryCell Label="A3"
                               Text="Hans Meier" />

                    <EntryCell Label="A4"
                               Text="Ivan Horvat" />

                    <EntryCell Label="A5"
                               Text="Jean Dupont" />

        <ActivityIndicator x:Name="activity" />

        <Button x:Name="button"
                Text="Create workbook"
