Migrating from React Data Grid (adazzle)

react-data-grid is a fast, Excel-like React grid with a clean column API. SvGrid mirrors its shape - virtualized DOM, typed columns, inline editing, custom cells - on Svelte 5 runes instead of React, so the port is mostly a column rename pass.

Estimated effort: 2-4 hours per grid, more if you lean on custom editors.

Facts, checked 12 Sep 2026. react-data-grid 7.0.0-beta.61, MIT, last published 14 Jul 2026, 2,180,000 npm downloads in the 30 days to 10 Sep 2026. @svgrid/grid 3.0.3, MIT, last published 11 Sep 2026, 16,900 npm downloads in the same window. Bundle, minified and gzipped, each package built alone with Svelte external: SvGrid 3.0.4 97.6 KB JS + 10.5 KB CSS (measured 22 Sep 2026); react-data-grid 7.0.0-beta.61 15.7 KB JS + 2.1 KB CSS, react + react-dom external (measured 12 Sep 2026). React Data Grid pricing, as its site states it: react-data-grid is MIT on npm and free; no licence is sold (https://github.com/adazzle/react-data-grid, read 12 Sep 2026). SvGrid: MIT core; @svgrid/enterprise from $299 per developer per year (Indie, under $1M revenue), $599 for Enterprise. Side by side, with sources: SvGrid vs React Data Grid (adazzle).

Vocabulary cheat sheet

Before / after

The example at the end of this page runs against these rows:

<script lang="ts">
  import { SvGrid, type GridColumns } from '@svgrid/grid'

  type Person = {
    id: number
    name: string
    department: string
    city: string
    age: number
    salary: number
  }

  const people: Person[] = [
    { id: 1, name: 'Ada Lovelace',   department: 'Engineering', city: 'London',   age: 36, salary: 142000 },
    { id: 2, name: 'Grace Hopper',   department: 'Engineering', city: 'New York', age: 45, salary: 168000 },
    { id: 3, name: 'Linus Torvalds', department: 'Platform',    city: 'Portland', age: 54, salary: 155000 },
    { id: 4, name: 'Radia Perlman',  department: 'Networking',  city: 'Seattle',  age: 49, salary: 161000 },
    { id: 5, name: 'Barbara Liskov', department: 'Platform',    city: 'Boston',   age: 52, salary: 172000 },
  ]

  let rows = $state<Person[]>(people)

  const columns: GridColumns<Person> = [
    { field: 'name',       header: 'Name',       width: 200, editorType: 'text' },
    { field: 'department', header: 'Department', width: 150, editorType: 'text' },
    { field: 'city',       header: 'City',       width: 140, editorType: 'text' },
    { field: 'age',        header: 'Age',        width: 90,  editorType: 'number' },
    { field: 'salary',     header: 'Salary',     width: 130, editorType: 'number', format: { type: 'currency', currency: 'USD' } },
  ]
</script>

- import DataGrid, { textEditor } from 'react-data-grid'
- const columns = [
-   { key: 'name',   name: 'Name' },
-   { key: 'amount', name: 'Amount', renderEditCell: textEditor },
- ]
- <DataGrid columns={columns} rows={rows} rowKeyGetter={(r) => r.id} onRowsChange={setRows} />

+ <script lang="ts">
+   import {
+     SvGrid, tableFeatures, rowSortingFeature, columnFilteringFeature,
+     type ColumnDef,
+   } from '@svgrid/grid'
+   const features = tableFeatures({ rowSortingFeature, columnFilteringFeature })
+   const columns: ColumnDef<typeof features, Row>[] = [
+     { field: 'name',   header: 'Name' },
+     { field: 'amount', header: 'Amount', editorType: 'text' },
+   ]
+ </script>
+
+ <SvGrid data={rows} columns={columns} features={features}
+   getRowId={(r) => r.id} enableInlineEditing
+   onCellValueChange={(e) => save(e)} />

What changes

• React → Svelte 5. renderCell / renderEditCell become renderSnippet snippets and editorType.
• onRowsChange → onCellValueChange. SvGrid writes to its own working copy; subscribe to commits and persist where you like.
• Filtering UI is built in. react-data-grid leaves the filter row to you; SvGrid ships the Excel-style menu.

Frequently asked questions

How do react-data-grid columns map to SvGrid?

key becomes field, name becomes header, renderCell becomes a renderSnippet cell, and editors map to editorType (or a custom cellEditor snippet). rowKeyGetter becomes getRowId.

Is SvGrid free like react-data-grid?

Yes - @svgrid/grid is MIT-licensed, like react-data-grid. SvGrid adds an optional paid Enterprise pack for export, import, pivot, and AI.

Does SvGrid have built-in filtering?

Yes. react-data-grid asks you to build the filter UI; SvGrid ships an Excel-style column filter menu and a global filter out of the box.

What you end up with

Inline editing with cell-range selection, which is the reason most people picked it.

<SvGrid data={rows} {columns} editable enableCellSelection sortable />
