Developer Tools Hub

Why this matters

Developers spend a surprising amount of time formatting and converting data between representations: pretty-printing JSON for debugging, minifying HTML for production, hashing a string for a cache key, reshaping CSV into SQL inserts. Most of these tasks are 30 seconds of work if you have the right tool — and 30 minutes if you don't.

Every tool in this hub runs locally: your data never leaves the browser. Formatters (JSON, HTML, SQL) parse with the right engine and re-emit clean output. Converters (MySQL ↔ Excel, JSON ↔ CSV) handle edge cases like escaped quotes and NULL values correctly. Hash generators use the browser's Web Crypto API. Pick the tool you need from the cards below.

Common workflows: formatting minified JSON from an API response into something readable, hashing a file's contents for a cache key, generating SQL inserts from a CSV export, minifying HTML for a production email template, and validating a JSON payload's structure before sending it to a server.
