ClosedXML
A .NET library for reading, manipulating, and writing Excel 2007+ files with an intuitive API.
What is ClosedXML?
ClosedXML is a .NET library that enables developers to programmatically create, read, and modify Excel 2007+ files (.xlsx, .xlsm) without needing Microsoft Excel installed. It serves as a high-level wrapper around the OpenXML SDK, simplifying tasks like generating reports, exporting data, and manipulating spreadsheet content directly from .NET applications. The library abstracts the underlying XML complexity, offering a more intuitive and productive API for Excel automation.
.NET developers who need to generate Excel reports on servers, automate spreadsheet tasks, or integrate Excel file processing into their applications without relying on Excel Interop or complex low-level APIs.
Developers choose ClosedXML because it provides a clean, straightforward API that significantly reduces the learning curve and development time compared to using the raw OpenXML SDK directly. It balances performance for large files with ease of use, making it a go-to solution for server-side Excel generation in .NET ecosystems.
Overview
ClosedXML is a .NET library for reading, manipulating and writing Excel 2007+ (.xlsx, .xlsm) files. It aims to provide an intuitive and user-friendly interface to dealing with the underlying OpenXML API.
