DropBoard: Drop a CSV. Get a dashboard. No signup, no server.

I built this because I kept getting CSV exports from clients and opening them in Excel just to answer one question: "what changed this month?" The thing that annoyed me most about existing tools is that they all want my data on their server. For a 40-row export. So I made something that runs entirely in the browser tab and works with the wifi off. It's a single HTML file — under 30 KB, no dependencies, no install. Download once, it's yours. No subscription. Try it right here without downloading anything: https://goodyuanbo.github.io/dro... (free Lite version, 500-row limit) The full version is $19 one-time: filters, PNG/standalone-HTML export, dark mode. I also put together a $99 bundle of everything in my store (6 tools for freelancers/small business) if you want the whole toolkit: https://boboyuan.gumroad.com/l/e... Happy to answer anything. If it chokes on a file, send it to me and I'll fix it.
