The browser-based data workbench for developers and data people.
DataBench is a free, browser-based workbench with 30+ tools built for developers, data analysts, and anyone who works with data files daily. It brings together the most commonly needed data utilities — JSON formatting, CSV conversion, SQL generation, regex testing, Base64 encoding, PDF tools, and more — into a single fast tab. No installation required. No account needed. Just open the site and start working.
Every developer knows the routine: you need to format a JSON response, so you Google "json formatter", land on a slow ad-heavy website, paste your data in, and hope for the best. Then you close the tab and do the exact same thing next week.
We were tired of that workflow — and more importantly, uncomfortable pasting sensitive data (API responses, database exports, config files with credentials) into random websites with unknown server-side logging. DataBench solves both problems at once: one bookmark, every tool you need, nothing ever leaves your browser.
Every tool on DataBench runs entirely client-side. When you paste a JSON file, encode a Base64 string, or work with a CSV, that data is processed locally on your machine using JavaScript — never transmitted to our servers, never logged, never stored. This isn't just a policy, it's the architecture: there is no backend server receiving your input. Full details on the Privacy Policy page.
