I built ChartThat because every other tool made a simple job feel like a project.

The story behind the tool · About

I work in advertising. Most of my Fridays end the same way: a spreadsheet full of numbers, a client pitch on Monday, and a deck full of charts that don't exist yet.

I tried everything. The AI chatbots wanted me to describe my CSV in a prompt, wait a while, then paste a picture of a chart into my slide — a flat image, impossible to restyle, useless the moment a number changed. The plugins wanted installs and accounts. The BI tools wanted a data warehouse. One chart cost ten minutes and a handful of tokens, when what I actually needed was almost embarrassingly simple: a table in, a PowerPoint chart out.

So I built the tool I wanted

Paste text, a CSV, or an Excel sheet. ChartThat reads the shape of your data, suggests the chart types that genuinely fit — thirteen of them, from combos to waterfalls — and exports a native, double-click-to-edit PowerPoint chart. Or an animated GIF, for the slides that need to move.

No sign-up. No chat window. Nothing to install. And your numbers stay yours — they are processed to draw your charts, never stored, and never fed into someone else's conversation.

What "native" means, and why it matters

Most tools hand you an image. ChartThat writes a real PowerPoint chart object into the .pptx file. Double-click it in PowerPoint, WPS, or Keynote, and the data sheet opens — change a number at 11pm the night before the pitch, and the chart redraws itself. That one detail is the whole reason this tool exists.

Free, and staying that way

ChartThat is free to use — no account, no watermark, no trial period. If it saves your Friday once, it has done its job. Sharing it with a colleague who also makes slides is the best way to say thanks.

If your Friday has ever been ruined by a "can we just add a quick chart?", this one's for you.
