Rawsort - Analyze CSV, JSON & Excel files entirely in your browser

by•
Rawsort is a free data analysis toolkit that runs 100% locally in your browser. Drop a CSV, JSON, or Excel file and get instant charts, trend detection, and insights no upload, no account, no cloud. Not "we delete it after 24 hours" private. Actually never-touch-a-server private. Includes a CSV↔JSON converter, CSV merger, and tools for Stripe and Shopify exports. All free, all local.

Rawsort started because I kept needing to quickly make sense of CSV exports Stripe payouts, Shopify orders, database dumps and every tool I found either wanted me to upload my data to their servers to see a chart. The original version was basically a single page that parsed a CSV and spat out a table. No charts, no insights, barely functional. It worked but it wasn't something I'd actually use regularly. I have updated our ui to be better and higher quality from our previous one Over the past few months it's grown into a full toolkit proper charts, trend detection, anomaly alerts, a copy-ready report, JSON and Excel support, converters, a CSV merger, and use-case pages for Stripe and Shopify specifically. Everything still runs 100% in the browser, that part never changed. But now it's actually something I open when I need to look at data instead of reaching for Excel. The core idea was always the same: your data is yours, it shouldn't have to touch a stranger's server just so you can see a bar chart of it. None of the files you upload leave your system
