A feature-rich, Excel-style data grid for React, Vue, Angular, and JavaScript.

GridNexa combines editing, import/export, charts, generated dashboards, filtering, grouping, pivoting, diagnostics, Data Health, Trust Mode, collaboration, saved views, validation, accessibility, and TypeScript-first APIs in packages designed for data-heavy applications.

GridNexa is distributed through public npm packages. The implementation repository is private while the project is in active development.

Current package version: 0.1.19.

pnpm add @gridnexa/react

import { GridNexa, type Column } from "@gridnexa/react";
import "@gridnexa/react/index.css";

interface Employee {
  id: number;
  name: string;
  department: string;
  score: number;
}

const columns: Column<Employee>[] = [
  { id: "name", field: "name", headerName: "Name", editable: true, filter: "text" },
  { id: "department", field: "department", headerName: "Department", filter: "set" },
  { id: "score", field: "score", headerName: "Score", editable: true, filter: "number" },
];

const rows: Employee[] = [
  { id: 1, name: "John Carter", department: "Operations", score: 92 },
  { id: 2, name: "Alice Moreau", department: "Product", score: 87 },
];

export function EmployeesGrid() {
  return (
    <GridNexa
      columns={columns}
      rows={rows}
      getRowId={(row) => row.id}
      rowNumbers
      checkboxSelection
      enableRangeSelection
      enableFillHandle
      enableUndoRedo
    />
  );
}

• Excel, CSV, TSV, text, and JSON import
• CSV and Excel export
• Range copy/paste, bulk edit, find and replace, fill handle, formulas, undo/redo

• Quick, column, set, number, and advanced filters
• Column resize, reorder, pin/freeze, hide, auto-size, flex, and fill-width layouts
• Grouping, aggregation, pivoting, summaries, tree data, master/detail, and transactions
• Data Health profiling for missing values, duplicates, invalid cells, outliers, completeness, top values, and quality scores
• Trust Mode with active-cell source, validation evidence, downstream-impact preview, edit history, and rollback
• Presets, saved views, persisted UI state, command palette, validation, and change review
• Provider-based realtime cell patches, presence badges, cell locks, and configurable conflict handling
• Diagnostics with repro JSON export and import
• Loading, error, and empty-state overlays
• Provider-neutral AI action plans and server-side operation callbacks
• Nine built-in theme values, density controls, styling tokens and slots, CSS variables, stable classes, custom icons, and unstyled mode
• Per-column header and cell styles plus ellipsis, clip, wrap, tooltip, and line-clamp text controls
• Accessible grid semantics, live announcements, roving cell focus, and comprehensive keyboard navigation

Generate a dashboard from the current visible grid view:

<GridNexa
  columns={columns}
  rows={rows}
  toolbar={{ dashboard: true, charts: true, filters: true }}
  dashboard={{ showPanel: true, maxCards: 4, maxRows: 500 }}
/>

Help users understand and safely revise the active value:

<GridNexa
  columns={columns}
  rows={rows}
  getRowId={(row) => row.id}
  toolbar={{ trustMode: true, dataHealth: true }}
  trustMode={{ showPanel: true }}
  dataHealth
/>

Realtime collaboration is provider-neutral. Connect a Socket.IO, WebSocket, Supabase Realtime, Firebase, Yjs, or internal event provider through the collaboration prop. GridNexa supports cell changes, presence, cell locks, and conflict modes while preserving application-owned transport and authentication.

GridNexa implements grid, row-group, and grid-cell semantics; row and column indexes; active-cell announcements; and roving focus. Keyboard support includes arrow navigation, Shift+Arrow range extension, Home/End, Ctrl/Cmd+Home/End, Page Up/Down, Enter or F2 to edit, Escape to cancel, and Ctrl/Cmd+C to copy.

Built-in themes are modern-light, modern-dark, compact, minimal, enterprise, high-contrast, light, dark, and system. Use the styling prop for typed theme tokens and slot-level styles, or apply headerStyle, cellStyle, and textDisplay per column. See the React guide for a complete example.
