DataBench – Browser Data Workbench - JSON, CSV, Regex & more — all in your browser

DataBench is a free browser-based workbench for developers and data people. Format JSON, convert CSV, generate SQL, test Regex, encode Base64, preview Markdown, convert timestamps, and more — 25+ tools in one fast tab. Everything runs 100% client-side. No installs, no sign-up, no server. Your data never leaves your machine. Stop juggling bookmarks across slow, ad-heavy sites. Open DataBench, get it done.

Hey PH! I built DataBench after getting frustrated with fragmented tools, paywalls, and sites that upload your data to their servers. Would love feedback on what tools you’d want added next — or anything that feels off. What’s included: • JSON formatter & validator — syntax errors pinpointed by line • CSV cleaner — trim whitespace, dedupe rows, normalize headers, auto-detect delimiter • SQL formatter — keyword casing, clause indentation • XML formatter & validator • YAML ⇄ JSON converter • Text diff checker, case converter, word counter • Image converter, compressor, resizer (PNG/JPG/WebP) • Excel ⇄ CSV/JSON • PDF merge, split, rotate, compress
