BlazorDatasheet provides a Blazor component for creating Excel-like data grids, targeting Blazor developers who need to display and edit tabular data with rich features. It offers a performant solution for handling large datasets through virtualization and supports extensive customization for editors, formatting, and validation.

How It Works

The component utilizes a Sheet object to manage data and configuration, allowing data to be set per Cell or generated from lists of objects. It supports various CellValueType conversions and allows custom cell renderers/editors. Formulas are evaluated automatically when referenced cells change, and formatting is merged hierarchically for flexible styling. Data validation can be applied with strict or non-strict modes.
