GemBox.Spreadsheet is a .NET component that enables you to read, write, convert, and print spreadsheet files (XLSX, XLS, XLSB, CSV, HTML, and ODS) from .NET applications.
With GemBox.Spreadsheet you get a fast and reliable API that’s easy to use and doesn’t depend on Microsoft Excel. It requires only .NET, and it’s much faster than Microsoft Office Automation!
You can download and use the component for free, even for commercial projects. The Professional version, which comes with 12 months of technical support and without limitations, requires a license for every developer. There are no OEM, server, or deployment licenses. We also offer a 30-day money-back guarantee.
