Frequently Asked Questions
Everything you need to know about FastGrid
What is FastGrid and who is it for?
FastGrid is a high-performance JavaScript data grid designed for enterprise applications working with large volumes of data.
It's built for developers and teams who need to smoothly display, edit, and analyze millions of rows or columns directly in the browser.
How does FastGrid handle millions of rows without pagination?
FastGrid uses virtual scrolling and lazy loading — only the currently visible cells are rendered in the DOM.
The result is smooth, gap-free scrolling even on extremely large datasets.
Does FastGrid have built-in AI support?
Yes. FastGrid natively integrates OpenAI ChatGPT, with users bringing their own OpenAI API license.
The AI can search the web, generate images, filter data using AI-generated regular expressions, and fully control and manipulate very large grids.
Integration with other AI vendors is also supported.
Which JavaScript frameworks does FastGrid work with?
FastGrid supports React, Vue, Angular, Svelte, Ember, Express, and SalesForce LWC — in both JavaScript and TypeScript.
It can also be used in plain Vanilla JS or any other client-side framework that supports third-party JS code.
What data formats does FastGrid support for import and export?
Data can be loaded and exported in JSON, XLSX, and CSV formats.
PDF and HTML export is also available with full formatting preserved.
FastGrid also offers its own ultra-fast UTF8 Store format for maximum performance.
Can FastGrid be used without writing custom JavaScript?
Yes. FastGrid is designed to be fully operable through the user interface or via AI, without the need to write any custom JavaScript code.
What editing capabilities does FastGrid offer?
FastGrid provides Excel-like editing — including keyboard navigation, auto-complete, input validation, input masks, multi-row editing,
a rich text editor, a calendar picker for date cells, and image insertion.
Auto-fill and smart fill-down operations are also supported.
Does FastGrid support formulas and calculations?
Yes. FastGrid includes a complete Excel-compatible formula engine with over 200 functions, support for JavaScript-based formulas and calculations,
and direct access to the full grid API from within formulas.
What analytical features are available?
FastGrid supports dynamic pivot tables with drag-and-drop configuration, multi-level grouping, Excel-style auto-filtering,
full-text search, row and column sorting and filtering, aggregation functions (sum, average, count, etc.), and conditional formatting.
Which browsers does FastGrid support?
FastGrid is compatible with all modern browsers: Chrome, Edge, Safari, Firefox, Opera, Android WebView, and Samsung Internet.
All rendering engines — WebKit, Gecko, and Blink — are supported.
How does FastGrid differ from the older TreeGrid product?
FastGrid brings significantly faster rendering and scrolling compared to TreeGrid, zero blank areas during scrolling,
built-in AI integration, support for millions of rows without pagination, a compact UTF8 Store format, per-row custom column structures,
and unlimited independently scrollable sections.
What are the server integration options?
FastGrid connects to any backend returning JSON. Ready-made server-side code examples include Node.js, ASP.NET (C# and VB), JSP (Java), and PHP.
Communication is handled via AJAX, form submits, or a custom API.
Can FastGrid be visually customized?
Yes. FastGrid supports full theming via JSON configuration, both built-in and custom themes, responsive design with touch support,
localization into any language, and user-managed configuration profiles.
Is there an official npm package for FastGrid?
Yes. As of version 3.2, FastGrid has official npm packages and example projects for React, Angular, Vue and Svelte, plus a plain HTML/JavaScript example.
See the "Use & Integrate" section.
Can I use FastGrid without a frontend framework?
Yes, via the HTML/JavaScript example linked in the framework documentation.
Is there a backend example?
Yes, a Node.js example is included. FastGrid also works with any backend that returns JSON (ASP.NET, Java/JSP, PHP examples are included in the package).
Where do I find framework-specific setup instructions?
Each framework has a dedicated documentation page (React, Angular, Vue, Svelte, HTML/JS) linked from the "Use & Integrate" section and from the Download page.
Does the new npm package change licensing?
No. Licensing remains per developer/application with unlimited end users, no royalties, regardless of install method.
Do TreeGrid, GanttChart or SpreadSheet have the same npm packages?
Not currently. Framework packages exist for FastGrid and FastSheet only.
