ClosedXML

ClosedXML is an open-source .NET spreadsheet library and wrapper used for reading and writing Excel files. It provides an object-oriented interface for manipulating workbook structures and cell data within .xlsx and .xlsm files using the OpenXML standard.

The library abstracts the complexity of the OpenXML SDK, allowing developers to generate and modify spreadsheets programmatically without requiring Microsoft Office to be installed on the system.

It covers a range of spreadsheet management capabilities, including workbook generation, file loading, and data extraction. The toolset supports programmatic updates to spreadsheet layouts and the creation of formatted reports from application data.

Features

  • Excel Automation - Provides comprehensive tools for programmatically generating and modifying Excel spreadsheet files without requiring Microsoft Office.
  • OpenXML Spreadsheet Writers - Uses the official Microsoft OpenXML SDK as the underlying engine to read and write Excel files.
  • Automated Spreadsheet Report Generators - Enables the programmatic generation of formatted Excel reports from application data.
  • Excel Spreadsheet Management - Offers a simplified interface for modifying spreadsheet content, layouts, and cell structures.
  • Workbook Lifecycle Management - Enables the creation of new workbooks and the definition of their structural organization.
