Introduction

This How-To Guide explains how to create and read Excel files in .NET MAUI apps for Windows using IronXL. Let's get started.

IronXL: C# Excel Library

IronXL is a C# .NET library for reading, writing, and manipulating Excel files. It lets users create Excel documents from scratch, including the content and appearance of Excel, as well as metadata such as the title and author. The library also supports customization features for user interface like setting margins, orientation, page size, images and so on. It does not require any external frameworks, platform integration, or other third-party libraries for generating Excel files. It is self-contained and stand-alone.

Creating Excel Files in C# using IronXL

Design the Application Frontend

Open the XAML page named MainPage.xaml and replace the code in it with the following snippet of code.

<?xml version="1.0" encoding="utf-8" ?>
<ContentPage xmlns="http://schemas.microsoft.com/dotnet/2021/maui"
             xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"

                HorizontalOptions="Center" />

            <Button
                x:Name="createBtn"
                Text="Create Excel File"
                SemanticProperties.Hint="Click on the button to create Excel file"
                Clicked="CreateExcel"

                HorizontalOptions="Center" />

        </VerticalStackLayout>
    </ScrollView>

</ContentPage>

XML

The code above creates the layout for our basic .NET MAUI application. It creates one label and two buttons. One button is for creating an Excel file, and the second button provides support to read and modify the Excel file. Both elements are nested in a VerticalStackLayout parent element so that they will appear vertically aligned on all supported devices.

Create Excel Files

It's time to create the Excel file using IronXL. Open the MainPage.xaml.cs file and write the following method in the file.

private void CreateExcel(object sender, EventArgs e)
{
    // Create a new Workbook
    WorkBook workbook = WorkBook.Create(ExcelFileFormat.XLSX);

    // Create a Worksheet
    var sheet = workbook.CreateWorkSheet("2022 Budget");

    // Set cell headers
    sheet["A1"].Value = "January";
    sheet["B1"].Value = "February";
    sheet["C1"].Value = "March";
    sheet["D1"].Value = "April";
    sheet["E1"].Value = "May";
    sheet["F1"].Value = "June";
    sheet["G1"].Value = "July";
    sheet["H1"].Value = "August";

    // Fill worksheet cells with random values
    Random r = new Random();
    for (int i = 2; i <= 11; i++)
    {
        sheet["A" + i].Value = r.Next(1, 1000);
        sheet["B" + i].Value = r.Next(1000, 2000);
        sheet["C" + i].Value = r.Next(2000, 3000);

        sheet["H" + i].Value = r.Next(7000, 8000);
    }

    // Apply formatting (background and border)

    sheet["A11:H11"].Style.BottomBorder.SetColor("#000000");
    sheet["A11:H11"].Style.BottomBorder.Type = IronXL.Styles.BorderType.Medium;

    // Apply formulas

    decimal avg = sheet["B2:B11"].Avg();
    decimal max = sheet["C2:C11"].Max();

This source code creates a workbook and worksheet using IronXL, sets cell values, and formats the cells. It also demonstrates how to use Excel formulas with IronXL.

View Excel Files in the Browser

Open the MainPage.xaml.cs file and write the following code.

private void ReadExcel(object sender, EventArgs e)
{
    // Store the path of the file
    string filepath = @"C:\Files\Customer Data.xlsx";
    WorkBook workbook = WorkBook.Load(filepath);
    WorkSheet sheet = workbook.WorkSheets.First();

    // Calculate the sum of a range
    decimal sum = sheet["B2:B10"].Sum();

    // Modify a cell value and apply styles
    sheet["B11"].Value = sum;
    sheet["B11"].Style.SetBackgroundColor("#808080");
    sheet["B11"].Style.Font.SetColor("#ffffff");

    // Save and open the Excel file
    SaveService saveService = new SaveService();
    saveService.SaveAndView("Modified Data.xlsx", "application/octet-stream", workbook.ToStream());

    DisplayAlert("Notification", "Excel file has been modified!", "OK");
}

private void ReadExcel(object sender, EventArgs e)
{
    // Store the path of the file
    string filepath = @"C:\Files\Customer Data.xlsx";
    WorkBook workbook = WorkBook.Load(filepath);
    WorkSheet sheet = workbook.WorkSheets.First();

    // Calculate the sum of a range
    decimal sum = sheet["B2:B10"].Sum();

    // Modify a cell value and apply styles
    sheet["B11"].Value = sum;
    sheet["B11"].Style.SetBackgroundColor("#808080");
    sheet["B11"].Style.Font.SetColor("#ffffff");

    // Save and open the Excel file
    SaveService saveService = new SaveService();
    saveService.SaveAndView("Modified Data.xlsx", "application/octet-stream", workbook.ToStream());

    DisplayAlert("Notification", "Excel file has been modified!", "OK");
}

Private Sub ReadExcel(ByVal sender As Object, ByVal e As EventArgs)
	' Store the path of the file
	Dim filepath As String = "C:\Files\Customer Data.xlsx"
	Dim workbook As WorkBook = WorkBook.Load(filepath)
	Dim sheet As WorkSheet = workbook.WorkSheets.First()

	' Calculate the sum of a range
	Dim sum As Decimal = sheet("B2:B10").Sum()

	' Modify a cell value and apply styles
	sheet("B11").Value = sum
	sheet("B11").Style.SetBackgroundColor("#808080")
	sheet("B11").Style.Font.SetColor("#ffffff")

	' Save and open the Excel file
	Dim saveService As New SaveService()
	saveService.SaveAndView("Modified Data.xlsx", "application/octet-stream", workbook.ToStream())

	DisplayAlert("Notification", "Excel file has been modified!", "OK")
End Sub

$vbLabelText $csharpLabel

The source code loads the Excel file, applies a formula on a range of cells, and formats it with custom background and text coloring. Afterwards, the modified Excel file is saved and a notification is displayed.

Save Excel Files

In this section, we define the SaveService class that will save our Excel files in local storage.

Create a "SaveService.cs" class and write the following code:

using System;
using System.IO;

namespace MAUI_IronXL
{
    public partial class SaveService
    {
        public partial void SaveAndView(string fileName, string contentType, MemoryStream stream);
    }
}

using System;
using System.IO;

namespace MAUI_IronXL
{
    public partial class SaveService
    {
        public partial void SaveAndView(string fileName, string contentType, MemoryStream stream);
    }
}

Imports System
Imports System.IO

Namespace MAUI_IronXL
	Partial Public Class SaveService
		Public Partial Private Sub SaveAndView(ByVal fileName As String, ByVal contentType As String, ByVal stream As MemoryStream)
		End Sub
	End Class
End Namespace

$vbLabelText $csharpLabel

Next, create a class named "SaveWindows.cs" inside the Platforms > Windows folder, and add the following code:

using System;
using System.Collections.Generic;
using System.IO;
using System.Runtime.InteropServices.WindowsRuntime;
using Windows.Storage;
using Windows.Storage.Pickers;
using Windows.Storage.Streams;

        public async partial void SaveAndView(string fileName, string contentType, MemoryStream stream)
        {
            StorageFile stFile;
            string extension = Path.GetExtension(fileName);
            IntPtr windowHandle = System.Diagnostics.Process.GetCurrentProcess().MainWindowHandle;

            if (!Windows.Foundation.Metadata.ApiInformation.IsTypePresent("Windows.Phone.UI.Input.HardwareButtons"))
            {
                FileSavePicker savePicker = new FileSavePicker();
                savePicker.DefaultFileExtension = ".xlsx";
                savePicker.SuggestedFileName = fileName;
                savePicker.FileTypeChoices.Add("XLSX", new List<string> { ".xlsx" });

                WinRT.Interop.InitializeWithWindow.Initialize(savePicker, windowHandle);

                    {
