How to create an XML file from Excel
The .NET Framework offers a range of classes to facilitate reading, writing, and performing various operations on XML-formatted files.
Create an XML file from the contents of an Excel file
In the following program, we will demonstrate how to create an XML file from the contents of an Excel file. To achieve this, we will utilize an OleDbConnection to establish a connection to the Excel file and retrieve the data. The OleDbConnection class provides methods and properties to interact with various data sources, including Excel files.
Once the connection is established, we will read the Excel file and store the data in a Dataset. The Dataset is a powerful ADO.NET component that allows us to store, manipulate, and process data in a tabular format. By populating the Dataset with the data from the Excel file, we can easily manipulate and transfer the information to other formats, such as XML.
To create the XML file, we will call the WriteXml method of the Dataset. This method generates an XML representation of the Dataset and writes it to the specified file. The generated XML file will contain the data from the Excel file, structured according to the Dataset's schema.Full Source VB.NET

By exploring the capabilities of the OleDbConnection, Dataset, and the WriteXml method, we can effectively extract the data from the Excel file and create an XML representation of that data. This allows for easy integration with other systems and provides flexibility in working with XML-formatted files.
The provided program demonstrates how to create an XML file from the content of an Excel file using the OleDbConnection and Dataset classes. By reading the Excel file, storing the data in a Dataset, and utilizing the WriteXml method, we can generate an XML file containing the information from the Excel file in a structured format.
