In this video tutorial, we explore the IronXL and NPOI libraries for handling Excel files within a C# Windows Form application. Beginning with the installation of the necessary libraries via NuGet, the tutorial dives into creating a simple GUI with buttons for loading Excel files and exporting data to CSV and JSON formats. The process highlights the simplicity and speed of IronXL in comparison to the more complex and time-consuming NPOI library. IronXL's capability to convert Excel sheets directly into data tables with minimal code stands out, while NPOI lacks this functionality and takes longer to process large datasets. Additionally, only IronXL supports exporting Excel files to other formats like CSV and JSON. Throughout the tutorial, IronXL demonstrates its superior user-friendliness and efficiency, making it the preferred choice for developers looking to handle Excel files easily and effectively. The tutorial concludes with a demonstration of exporting files, reinforcing IronXL’s capabilities in providing swift and error-free operations.
