How to Convert a Data Table to an Excel File

In this tutorial, we explore the process of converting a data table into an Excel file programmatically using C# and the IronXL library. We begin by setting up a C# console application in Visual Studio, preferably using the latest version for optimal compatibility. After installing the IronXL library via the NuGet package manager or its website, we proceed to the program file.

The tutorial involves importing the IronXL library and System.Data namespace to handle data tables. A method is created to convert a data table into an Excel file, taking a file name as a parameter. We initialize a data table, define column headers, and input row data. A workbook object is then created with the Excel format, and a default worksheet is set up for data entry.

Using a loop, we insert data row by row into the worksheet, updating the cell values and incrementing the row count for new entries. Finally, the Excel file is saved using the "save as" function. The result is an Excel file generated from a data table, showcasing the simplicity and efficiency of the IronXL library for data manipulation and formatting.
