Overview
A .NET Excel spreadsheet API library is a programming interface that allows developers to programmatically create and manipulate Excel documents at scale. GrapeCity Documents for Excel is a solution that allows developers to import/export, create reports & templates, and deploy spreadsheets across desktop applications.

Fast and Efficient
Save memory and time with the lightweight API architecture. The more rows in the spreadsheet the faster our API is by comparison. Create, read, and edit Excel files from C# with just a few lines of code.

Full .NET Support for Windows, Linux, and Mac
Develop for all .NET platforms and operating systems with a single code base. Use in your apps for .NET Core, .NET Framework, Mono, Xamarin.iOS, and Xamarin Android.

Flexible Themes and Components
Empower users with customizable themes, configurable components, summary data, custom styles, embedded drawing objects, integrated calculation engine, and more.

Document Object Model
The interface-based API allows you to import, calculate, query, generate, and export any spreadsheet scenario. With the VS Tools for Office-style API, you can create custom styles using the same elements as VS Tools for Office.

Seamless Excel Compatibility
Lose nothing on import. Pivot tables, comments, charts, conditional formatting, data validation, formulas, shapes, pictures, sparklines, and tables stay intact.

Deploy Apps to the Cloud
Cloud-based deployment means you can be everywhere - with NuGet and Documents for Excel, you can deploy to Azure, AWS, and AWS Lambda.
