Embed Excel in Your App? An "Excel-Like" Library for .NET Developers — ReoGrid

What Is an Excel-Like Library?

It's a component that lets you embed an Excel-style spreadsheet view inside your application. Even without Excel installed, your app can deliver full spreadsheet functionality on its own.

• Enter values into cells
• Compute with formulas
• Apply borders, merged cells, and cell formatting
• Read and write Excel files

In other words, from your users' perspective, it's as if "Excel is built into the app."

What Is ReoGrid?

ReoGrid is an Excel-like library for .NET applications. Since its release in 2014, it has been adopted by companies and research projects in Japan and abroad.

Its appeal is in its simple, approachable architecture. Just add a single DLL and you can drop a spreadsheet onto your form right away.

But its biggest strength is performance.

• Smooth scrolling and rendering even with millions of rows
• Lightweight, with no unnecessary dependencies
• Reads and edits Excel (.xlsx) files
• Supports both WinForms and WPF

"Faster than other Excel-like libraries" is feedback we hear regularly from real-world projects.

Where Does It Shine?

ReoGrid is at its best in scenarios like these:

• Internal systems that need Excel-style data entry and display
• Displaying or printing complex business forms
• Importing and exporting Excel files
• Turning Excel-based tools into standalone apps for distribution
• Using Excel files directly as the application UI

It's used across manufacturing process control, financial-system data viewers, government business forms, and many more domains.

Summary

ReoGrid is one of Japan's leading libraries answering these needs — fast, easy to work with, and battle-tested.

If you've ever thought "I want to open an Excel file inside my app," or "I want to give my app an Excel-like feel," give ReoGrid a try.
