About
Toolbench is a free library of 75 browser-based utilities for everyday developer and data tasks, organised into seven categories: Text, Encode / Decode, Hash & Security, Converters, Random, ID Generators and Developer. Format, minify and compare JSON; convert CSV to JSON, SQL INSERT statements or a different delimiter; turn JSON into TypeScript interfaces or a JSON Schema; generate UUID v4/v7, ULIDs, NanoIDs and MongoDB ObjectIDs; create SHA-256, SHA-512, MD5 and HMAC digests; decode JWTs, test regexes and preview cron schedules. Every tool runs locally in your browser, with no account and nothing uploaded. Each page puts the tool first, then adds a short guide that explains the output, common mistakes and the next useful step, plus workflow links to related tools.
