What does the cron expression builder do?

It turns a 5-field cron expression into plain English and offers one-click presets (every day at 9am, every 15 minutes, weekdays, etc.) — handy for scheduling n8n, cron jobs, or any task runner.

Is my JSON or data sent anywhere?

No. The JSON formatter, Base64/URL encoders, UUID generator, and timestamp converter are 100% client-side JavaScript. Nothing is uploaded, logged, or stored.
