Millions of rows, no pagination, AI directly in a cell. How and where developers deploy FastGrid today — and why they choose it over the alternatives.
The problem is as old as web applications themselves: the user wants to see data. All of it, at once, fast. And you hand them a grid that starts stuttering at 50,000 rows, shows blank strips during fast scrolling, or just switches to pagination — and the user loses their place entirely.
FastGrid from COQsoft takes a different approach. Virtual scrolling with zero gaps, lazy loading, minimal DOM footprint. But what does that actually mean in practice? Where specifically are developers deploying this component, and what does it genuinely deliver?
Not every project needs a grid capable of handling millions of rows. But FastGrid shines wherever data grows faster than classic solutions can handle it without compromise.
A team building an internal sales dashboard needed to display the full order history — over 800,000 records — with the ability to filter, sort, and export to XLSX, without users ever losing their sense of where they were in the data.
A classic solution would have required aggressive pagination or server-side rendering with a complex cache. FastGrid fetches visible rows on the fly via lazy loading and keeps the rest in its optimised UTF8 Store format. The result: a grid with instant response, no blank gaps during scrolling, and one-click full-dataset export to XLSX.
Key technical decision: rather than sending all data to the frontend at once, the team used background loading via a JSON API. FastGrid pulls data progressively — the user never waits, no loading spinner ever appears.
An analytics tool for marketing needed pivot functionality accessible to non-technical users. Instead of a complex UI for configuring axes, aggregations, and filters, the team integrated FastGrid with OpenAI through its built-in AI interface.
The user types into the chat: "Show me revenue by region for Q1, sorted descending." The AI processes the query, translates it into API calls on the grid, and the result appears instantly as a pivot — no clicking, no learning curve.

A customer used complex Excel templates for production planning. Files were sent by email, versions diverged, and importing data back into the system was manual and error-prone.
The solution deployed FastGrid as an in-browser XLSX editor. A file is uploaded, opened in the grid with full formatting and validation preserved. Saving writes back to XLSX without losing a single style. A unique capability is each row having its own column structure — ideal for heterogeneous production templates.
FastGrid is available as a downloadable package with a fully functional trial version including examples for all supported frameworks and ready-made server-side scripts for Node.js, ASP.NET, JSP, and PHP.
For a quick proof of concept, simply point the component at a JSON endpoint and configure the columns — no custom JavaScript required. The AI extension requires your own OpenAI API key; prompt costs are reduced by FastGrid’s built-in caching.
If your project is hitting performance limits, struggling with pagination, or missing in-browser editing for large datasets — FastGrid is a strong first place to look.
