SpreadsheetGear
SpreadsheetGear is a .NET library for creating, reading, editing, and exporting Excel files without requiring Microsoft Excel to be installed. It provides a comprehensive API for manipulating spreadsheets, charts, formulas, and formatting, enabling developers to integrate spreadsheet functionality into applications. It supports various Excel formats including XLSX, XLS, CSV, and PDF export.
Developers should use SpreadsheetGear when building .NET applications that require programmatic generation or manipulation of Excel files, such as reporting tools, data analysis dashboards, or financial applications. It is particularly valuable in server-side environments where Excel automation via COM interop is unreliable or not feasible, offering better performance and stability.
