如何在 C# | IronXL 中作為資料集匯入和匯出

This video walks through opening and working with existing Excel files in VB.NET using IronXL. It covers loading an XLSX spreadsheet, accessing worksheets, reading cell values, and modifying and saving the file programmatically, with no Interop and no Excel installation on the machine. That makes it a good fit for reporting systems, automation tools, and internal business applications running on servers. The same approach reads and writes spreadsheet data from VB.NET with only a few lines of code.
