使用 C# 从 ASP.NET 将 DataTable 导出到 Excel

Question

I have an ASP.NET web forms app with a button on it. This button allows a user to download some content to Excel. However, I'm having problems getting it to work. Everyone has articles that are like export DataGrid or GridView to Excel. My problem is, I have a plain old DataTable. I can't put this DataTable in my UI. At the same time, I do not want to use the Excel libraries.

Does anyone know a way to export a DataTable to Excel with formulas?

Answer 1

You can use ClosedXML library (an OpenXML wrapper) to create any Excel you want dynamically.

Answer 2

Office Writer is a very powerful and equally expensive solution which I have used in the past. ClosedXML in Peters answer also looks good (and free).

If you don't need Formulas this answer to another SO question may help you out. No library required.
