Ready to roll? Let’s get started!

Prerequisites

Before we jump into the code, let’s make sure you have everything you need. Here’s what you’ll require:

  1. Visual Studio: Make sure you have Visual Studio installed on your machine. If you don’t have it yet, you can download it here.
  2. Aspose.Cells for .NET: You’ll need to add Aspose.Cells to your project. You can either download it from the site or use NuGet Package Manager in Visual Studio. You can find the package here.
  3. Basic C# Knowledge: You should be comfortable with basic C# programming concepts. If you’ve dabbled in coding before, you’re good to go!
  4. Output Directory: Decide where you want to save your Excel file. Create a folder on your machine to keep things organized. Now that you’ve got your prerequisites sorted, let’s dive into the coding part!

Import Packages

First things first: we need to import the necessary packages. This is how you let your code know which libraries to use. Here’s how to do it:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

This simple line of code is your gateway to accessing all the powerful functionalities that Aspose.Cells offers. Make sure to place it at the top of your C# file. Let’s break down the process into manageable steps, shall we? We’ll walk through each part of the code together.

Step 1: Set Up Your Output Directory

Before you do anything else, you need to set up your output directory. This is where your Excel file will be saved. Here’s how you can do that:

// Output directory
string outputDir = "Your Document Directory";

Replace "Your Document Directory" with the actual path where you want to save your file. For example, if you want to save it in a folder called “ExcelFiles” on your desktop, you would write:

string outputDir = @"C:\Users\YourUsername\Desktop\ExcelFiles\";

Step 2: Create a Workbook

Now that you’ve set the output directory, it’s time to create a new workbook. A workbook is basically an Excel file that can contain multiple worksheets. Here’s how you create one:

// Create workbook.
Workbook wb = new Workbook();

This line of code initializes a new instance of the Workbook class. You can think of this as opening a new blank Excel file, ready for you to fill it with data!

Step 3: Specify the Compliance Settings

Next, we need to specify that we want to save our workbook in the Strict Open XML Spreadsheet format. This is a crucial step for ensuring compatibility with other Excel programs. Here’s how to do it:

// Specify - Strict Open XML Spreadsheet - Format.
wb.Settings.Compliance = OoxmlCompliance.Iso29500_2008_Strict;

By setting the compliance to OoxmlCompliance.Iso29500_2008_Strict, you’re telling Aspose.Cells that you want your workbook to adhere strictly to the Open XML standards.

Step 4: Add Data to Your Worksheet

Now comes the fun part! Let’s add some data to our worksheet. We’ll write a message in cell B4 to indicate that our file is in the Strict Open XML format. Here’s how:

// Add message in cell B4 of first worksheet.
Cell b4 = wb.Worksheets[0].Cells["B4"];
b4.PutValue("This Excel file has Strict Open XML Spreadsheet format.");

In this step, we’re accessing the first worksheet (worksheets are zero-indexed) and inserting our message into cell B4. It’s like putting a sticky note in your Excel file!

Step 5: Save the Workbook

We’re almost there! The last step is to save your workbook to the output directory we specified earlier. Here’s the code to do that:

// Save to output Excel file.
wb.Save(outputDir + "outputSaveWorkbookToStrictOpenXMLSpreadsheetFormat.xlsx", SaveFormat.Xlsx);

This line of code takes your workbook and saves it as an .xlsx file in the specified directory. You can name your file anything you want; just make sure to keep the .xlsx extension.

Step 6: Confirm the Success

To wrap it all up, let’s add a little confirmation message to let us know everything executed successfully:

Console.WriteLine("SaveWorkbookToStrictOpenXMLSpreadsheetFormat executed successfully.");

This is a simple way to verify that your code ran without a hitch. When you run your program, if you see this message in the console, you’ve done it!
