# Compared with other pivot components

What people and developers can do with pivotkit and with six other pivot components, one row per task, each cell linked to the page it comes from. pivotkit aims at people who know Excel's PivotTable and at developers who put that report into their own application; the others choose differently, and [where others are stronger](<#where-others-are-stronger>) says where.

## The short answer

Among the components below, pivotkit is the only one we found that combines a field list for people without technical knowledge, loading their own CSV, JSON or Excel file in the report with a preview (where the host turns it on; Excel with a plugin), a switch between table and chart, views as JSON with a published JSON Schema, a native Excel export that keeps the pivot layout, the rows behind the report as a file, and the same report rendered without a browser by a library, a command line that checks views in CI, a REST service with a container image and an MCP server for AI clients; it is MIT-licensed.

- **Perspective** is the strongest engine for large and live data, has no built-in Excel export (its FAQ says so) and streams live data.
- **Graphic Walker** is a chart builder first; it lets people upload a CSV or JSON file with a preview, and needs React 19.
- **Flexmonster** is a complete paid pivot tool: rules, top N, 13 languages, raw rows from its drill-through view; it exports in the browser (on a server through a headless browser).
- **AG Grid Enterprise** is a data grid with a paid pivot mode, server-side pivoting and 46 locales.
- **WebDataRocks** is free of charge but proprietary, capped at 1 MB of data.
- **PivotTable.js** has had no release since 2018; react-pivottable keeps its React wrapper current.

## What you can do

Checked on 2026-11-14 in each project's own documentation, README, wiki or npm entry; cells marked ¹ were checked on 2026-11-12 or 2026-11-13 and not again. "Not found" means not found in the pages looked at, on that date; it is not proof of absence. Paid features say so. The table scrolls sideways on a small screen.

## Where others are stronger

- **More rows in the browser**: [Perspective](<https://perspective-dev.github.io/guide/use_cases/large_datasets.md>) computes in C++ compiled to WebAssembly in a Web Worker, so the page stays responsive, and names millions of rows as routine; it also streams updates and runs the same engine on a server or as SQL against DuckDB, ClickHouse, PostgreSQL and Polars. Its `restore()` checks a saved config and `migrate()` updates old ones. pivotkit computes on the page: at 1,000,000 rows the first table takes 1 to 2.5 s on an Apple M4 and the page is frozen meanwhile ([measured](<https://pivotkit.eize.dev/concepts/limits/#measured-in-the-browser>)).
- **Charts**: Perspective draws more than 15 chart types with WebGL; Graphic Walker is a chart builder first (Vega-Lite). pivotkit draws bars, lines, area, pie, donut and heatmap ([charts](<https://pivotkit.eize.dev/use/charts/index.md>)).
- **A full data grid**: AG Grid is a data grid with several row models, [server-side pivoting](<https://www.ag-grid.com/react-data-grid/server-side-model-pivoting/>) and an [Excel import](<https://www.ag-grid.com/react-data-grid/excel-import/>) by drag and drop; pivotkit is a pivot report, not a grid.
- **Languages and data sources**: AG Grid ships 46 locales, Flexmonster localization files for 13 languages, WebDataRocks 11; Flexmonster connects to Microsoft Analysis Services, SQL databases, MongoDB and Elasticsearch. pivotkit ships English and German, every text replaceable ([localisation](<https://pivotkit.eize.dev/reference/localisation/index.md>)).
- **Raw rows and accessibility in Flexmonster**: its drill-through view lists the records behind a value and exports them, and its [accessibility page](<https://www.flexmonster.com/doc/accessibility-overview/>) says it follows guidelines based on WCAG 2.1 and Section 508, with a high-contrast theme.
- **Files people bring**: Graphic Walker lets people upload a CSV or JSON file, preview it and set each column's role; top N and an Excel export were not found in its docs.
- **Size**: PivotTable.js's core is 6.3 KB gzip by its README, without charts. pivotkit's web component loads about 172 KiB gzip first, with React inside, and the chart's code (about 216 KiB gzip, ECharts with it) on the first chart (measured with `npm run size -w pivotkit-element` on 2026-11-14; [bundle size](<https://pivotkit.eize.dev/reference/element/#bundle-size>)); Graphic Walker's FAQ names about 1.5 MB minified, roughly 400 KB gzip, with Vega-Lite.
- **Maturity and support**: AG Grid, Flexmonster and WebDataRocks are commercial products with vendor support and years in production, Perspective and PivotTable.js have long track records; pivotkit is in 0.x (the version and date are in the table above) and its API can still change between minor versions.
- **Calculated values and more chart types**: Flexmonster has calculated values with a formula editor and charts such as scatter and column-line combinations; pivotkit has neither.

## What pivotkit does not do

- The report does not fetch data and makes no network request: the host passes the rows, or a person loads a file of their own in the browser where the host allows it (`allowImport`, off by default; [FAQ](<https://pivotkit.eize.dev/faq/#my-data-is-on-a-server-does-pivotkit-fetch-it>)). The command line reads local files only; the REST service and the MCP server, which an operator runs, read the files their configuration names and answer requests.
- It is not access control: a viewer can see every row the host passes, and with Source data (`exportData`, off by default) download them ([security](<https://pivotkit.eize.dev/security/#pivotkit-is-not-access-control>)).
- The report computes on the page, not in WebAssembly or a worker, and has no server row model or streaming updates. For more than a million rows, aggregate on the server first ([more than a million rows](<https://pivotkit.eize.dev/concepts/limits/#more-than-a-million-rows>)).
- It is a pivot report, not a data grid or a dashboard tool: no editing of cells, no calculated fields from formulas, no dashboards of several reports.
- No conformance level of WCAG is claimed, and it ships two UI languages.

## Each in detail

> [!NOTE]
>
> **Perspective**
>
> - Packages `@perspective-dev/*` (5.9.1 on 2026-11-12; `@finos/perspective*` stopped at 3.8.0 in 2025); the React wrapper `@perspective-dev/react` accepts React `>17 <20`. Member project of the OpenJS Foundation.
> - Pivot: group by (rows, with subtotals), split by (columns), many aggregates, expressions, date buckets; drag and drop in its column list. Top N: not found in its docs.
> - Export: the viewer downloads the current view as CSV or Arrow; `export()` gives CSV, Arrow and HTML, a chart as PNG. Its [FAQ](<https://perspective-dev.github.io/guide/FAQ.md>): "Perspective does not have built-in Excel export."
> - Saved views: `save()` and `restore()` as a JSON config; `restore()` rejects keys the format does not define, `migrate()` updates configs since 2.0.0.
> - Loading a file in the viewer and an accessibility statement: not found in its guide.
> - It publishes `llms.txt` and `llms-full.txt` for its docs.

> [!NOTE]
>
> **Graphic Walker**
>
> - A Tableau-like React component: drag fields onto shelves for rows, columns, colour and more. 0.6.0 needs React 19 (`react >=19.0.0`) and adds nested row and column headers, aggregate filters and a CSV, SVG and PNG export of the worksheet.
> - Its README: "upload your Data(csv/json) file, preview your data, and define the analytic type of columns (dimension or measure)".
> - Pivot: a `PivotTable` component is exported from the package and named in the 0.6.0 release notes; not found in its README or docs site.
> - Rows ([FAQ](<https://docs.kanaries.net/graphic-walker/faq>)): under 10K excellent, 10K-100K good, 100K-1M usable, above 1M server-side computation; it "requires a browser environment for rendering".
> - Saved charts: a JSON spec, with a JSON Schema for its TerseSpec format. UI languages: English, Chinese, Japanese, and your own.
> - Subtotals, top N, .xlsx export and an accessibility statement: not found in its README or docs.

> [!NOTE]
>
> **PivotTable.js and react-pivottable**
>
> - PivotTable.js needs jQuery and jQuery UI; its last commit is from 2024-01-06. react-pivottable 0.11.1 (2026-03-13) updated a dependency for React 19; the release before it is from 2020-11-19.
> - Drag and drop UI for rows and columns, one aggregator at a time, derived attributes (a date format deriver), table, heatmap and chart renderers (Plotly, C3, D3, Google Charts). Subtotals come from a third-party renderer named in its wiki. PivotTable.js has 14 locale packs besides English; react-pivottable none.
> - Its [FAQ](<https://github.com/nicolaskruchten/pivottable/wiki/Frequently-Asked-Questions>): "PivotTable.js is designed to be a browser-side component"; export is out of scope, with a TSV renderer to copy into Excel.
> - Open requests in react-pivottable: [Excel and PDF export](<https://github.com/plotly/react-pivottable/issues/168>), [click events](<https://github.com/plotly/react-pivottable/issues/40>).

> [!NOTE]
>
> **AG Grid Enterprise**
>
> - Pivot mode, row groups and aggregation with a side bar and pivot panel; pivoting, the Excel export, the Excel import and integrated charts are Enterprise features.
> - Grid state, the pivot among it, saves as a JSON object with a version and converts old state ([grid state](<https://www.ag-grid.com/react-data-grid/grid-state/>)).
> - In pivot mode "it is not possible to drill all the way down the leaf levels" ([server-side pivoting](<https://www.ag-grid.com/react-data-grid/server-side-model-pivoting/>)).
> - Excel export: groups and merged header groups; "Cell styles will NOT be exported by default".
> - Its [accessibility page](<https://www.ag-grid.com/react-data-grid/accessibility/>) describes a WCAG and ARIA approach; a conformance claim was not found there.

> [!NOTE]
>
> **Flexmonster**
>
> - Paid licences for a company, SaaS and OEM; a trial of at most 30 days, watermarked, for evaluation only (clause 3.1.1 of its [licence agreement](<https://www.flexmonster.com/software-license-agreement/>), "Last updated: October 15, 2026").
> - Rows: "you can load more than 1GB of data and display up to 1 million rows of grouped data" ([introduction](<https://www.flexmonster.com/doc/introduction/>)).
> - [Export](<https://www.flexmonster.com/doc/export-report/>) to PDF, Excel, CSV, HTML and image, with caveats: "A node is not included in the exported file if its parent nodes are collapsed", and "the chart view or the grid and charts view can be exported only to PDF, HTML, or an image". Without a browser it recommends a headless browser (Puppeteer).
> - People load a local CSV or JSON file through Connect; Excel is not listed.
> - UI languages: localization files for 13 languages ship with it ([localizing](<https://www.flexmonster.com/doc/localizing-component/>)); data from Microsoft Analysis Services, SQL databases, MongoDB and Elasticsearch, some through its own server tools ([data sources](<https://www.flexmonster.com/doc/supported-data-sources/>)).
> - Reports save as a JSON object ([save and restore](<https://www.flexmonster.com/doc/save-and-restore-report/>)).
> - [Accessibility](<https://www.flexmonster.com/doc/accessibility-overview/>): "Flexmonster follows accessibility guidelines based on WCAG 2.1 and Section 508 standards"; no conformance level or audit named there.
> - Wrappers on npm: `react-flexmonster` for React 17 to 19, `ngx-flexmonster` for Angular 12 or later, and `vue-flexmonster`.

> [!NOTE]
>
> **WebDataRocks**
>
> - Free of charge but not open source. Its [licence](<https://www.webdatarocks.com/license-agreement/>) (revision date October 20, 2026) forbids to "change, remove, disable, circumvent, or modify any: limitations included in Proprietary Code, including the 1 MB limitation on the data size loaded to WebDataRocks" and any "proprietary notice, copyright notice or label (e.g., WebDataRocks logo and/or "WebDataRocks.com" text displayed when the WebDataRocks reporting tool is running)".
> - Packages: `@webdatarocks/webdatarocks` 1.4.23 (2026-04-13); the unscoped `webdatarocks` and `react-webdatarocks` (1.4.9, 2023-10-19) are deprecated. The React wrapper `@webdatarocks/react-webdatarocks` still declares React `^17.0.1`; React 18 and 19 are not mentioned in its docs.
> - [Export](<https://www.webdatarocks.com/doc/js/exporting/>) "to a file in which format is the most convenient for you – PDF, Excel or HTML. Besides, you can print it as well."
> - People load a local CSV or JSON file from the toolbar; the drill-through view is view-only.
> - Charts: its docs describe integrations with amCharts, Highcharts, Google Charts and FusionCharts; charts of its own were not found.

> [!NOTE]
>
> **pivotkit**
>
> - Subtotals and grand totals, aggregations with "show values as", date grouping, filters with relative date ranges and top N, drill-down, undo and redo ([feature list](<https://pivotkit.eize.dev/features/index.md>)).
> - Loading a CSV, JSON or Excel file in the report, with a preview, a type per column and a sheet picker, where the host allows it ([load your own data](<https://pivotkit.eize.dev/use/load-data/index.md>)); the rows behind the report as CSV or JSON, where the host allows it ([the table or the rows](<https://pivotkit.eize.dev/use/export/#the-table-or-the-rows-behind-it>)).
> - Views: versioned JSON with a published [JSON Schema](<https://pivotkit.eize.dev/reference/view-file/index.md>), shared as a file, as JSON or as a link; rendered without a browser by [pivotkit-report](<https://pivotkit.eize.dev/reference/report/index.md>) and the [command line](<https://pivotkit.eize.dev/reference/cli/index.md>), which also checks them in CI.
> - Keyboard and screen readers: every action by keyboard and by a menu ([keyboard](<https://pivotkit.eize.dev/use/keyboard/index.md>)); no conformance level is claimed.

## How this page was made

Each fact comes from the project's own documentation, its npm entry or its GitHub repository, linked in the table, and was checked on the date given; a page that only summarised itself to the tool that read it (Flexmonster's site refuses plain downloads) is no less linked, but worth a second look in a browser. Prices are left out; the licence links lead to them. The comparison on 2026-11-06 also covered, among others, MUI X Premium, Syncfusion, DevExtreme, Handsontable, RevoGrid and Univer (pivoting only in a paid edition), TanStack Table, Tabulator and Glide (no pivot UI), DuckDB-WASM and Arquero (engines without a UI), and Orb and Voyager; these were not checked again for this page. Corrections are welcome as an [issue](<https://github.com/eizedev/pivotkit/issues>).
