About chart.video

A chart that moves holds attention in a way a still one can’t: bars overtaking each other, a line climbing year by year, a total counting up to its final figure. Making one, though, usually means an account, an upload, a paid plan to download the video, or an afternoon in motion-graphics software. chart.video is a single browser tab that goes from a pasted table to a finished video file, with the data staying on your computer the whole time.

What you can make

• Bar chart races, animated bars and columns (grouped or stacked), lines that draw themselves, and stacked areas.
• Pies and donuts that morph between years, number counters, bubble races, treemaps, waffles, progress bars and gauges, and A vs B comparisons.
• MP4 video at 1080p or 4K and 30 or 60 frames per second, GIFs, transparent WebM overlays and PNG stills.
• Landscape for YouTube and slides, vertical for TikTok, Reels and Shorts, and square or 4:5 for feeds, with safe areas kept clear.

How it works

The site is a static web app. Pasted cells and opened files are parsed in the page: number formats, dates and the table’s layout are worked out automatically, and anything that can’t be read is explained in plain English. A single drawing function paints each frame of the chart on a canvas from the data and the time, with values eased between periods, overtakes smoothed and labels kept apart. The preview calls it as the video plays; the export calls the same function for every frame at full size in a background worker and encodes the result with the browser’s WebCodecs API and the open-source mediabunny library, so the file matches the preview exactly.

Charts are saved in this browser’s storage, so you can close the tab and continue later. They never leave the device.

Who it is for

YouTubers and TikTok creators telling a story with numbers; analysts and teachers who want a chart to land in a presentation; journalists and charities making a quick social graphic; small businesses celebrating a milestone. If you’re starting out, the bar chart race maker and the animated line chart maker open with sample data ready to replace, and the Excel and Google Sheets guide shows how to bring your spreadsheet across.
