This tutorial provides a comprehensive guide on creating and reading Excel files in VB.NET using IronXL. Initially, ensure Visual Studio and IronXL are installed via the NuGet Package Manager for optimal compatibility and performance. The tutorial walks through the Program.vb file, showcasing how to import necessary namespaces and declare the main method. To create an Excel file, instantiate a Workbook object with the format .xlsx and add a worksheet named 'Sheet1'. Assign values to specific cells and save the file as 'sample.xlsx'. For reading data, load a workbook from the specified file path into a Workbook object, retrieve the worksheet, and iterate through a range of cells to print their values. The tutorial concludes by running the program to verify the output in both the console and the newly created Excel file. Offering a simple yet effective approach, this guide demonstrates the ease of managing Excel files in VB.NET applications using IronXL. Subscribe for more tutorials from Iron Software.
