ReoGrid is an open-source .NET spreadsheet component (MIT Community Edition, V3) that embeds an Excel-like grid into WinForms and WPF applications, with formula calculation, charts, cell styles, freeze panes, outlines, and XLSX import/export. This repository is the free V3 edition; the vendor's newer V4/V5 editions and web versions are commercial products.
Use cases
- embed an excel-like spreadsheet grid in a winforms app
- read and write xlsx files from a .net application
- add formula calculation to a wpf data grid
- display editable tabular data with cell formatting and charts
- build a spreadsheet editor with freeze panes and outlines
- import excel workbooks preserving formulas and merged cells
When to choose
- you need a free MIT-licensed spreadsheet control inside a .NET WinForms or WPF app
- you need Excel .xlsx import/export with formulas, styles, and merged cells preserved
- you want built-in formula evaluation, charts, and cell types without COM/Excel interop
When to avoid
- you need the newest features like lazy loading of 1M+ rows, Avalonia support, or commercial support (those are in paid V4/V5)
- you are building a web app with React or Vue (the web edition is a separate commercial product)
- you need a headless server-side spreadsheet engine rather than an interactive UI control
