Developer & Automation Tools
Essential developer tools for JSON processing, cron scheduling, automation and focused work. Format and validate JSON, generate cron expressions, and stay in deep work mode with a Pomodoro timer and soothing city backgrounds.
All tools run 100% client-side for privacy and speed. Ideal for API debugging, config validation, CI/CD pipelines, and distraction-free study or coding sessions.
Available Tools
- JSON Formatter & Parser – format, validate, parse to tables, minify, and export JSON to CSV with clean indentation.
- Cron Expression Generator – build, validate and explain 5-field cron schedules for Linux crontab and cloud schedulers.
- Pomodoro Timer with City Wallpapers – 25 & 30 minute focus sessions, short and long breaks, pause/resume controls and high-tech city skylines like Bangalore, Tokyo, San Francisco, New York, Singapore and European cities.
JSON Formatter Features
Debug API responses with formatted JSON, explore nested arrays in simple tables, validate structure before deployment, and minify for production to reduce payload size.
Cron Generator Features
Create complex schedules like "every weekday at 2:30 AM" and get the exact cron string plus a plain-English explanation. Paste existing jobs to audit, visualise and debug quickly.
Pomodoro Timer Features
Switch between 25 or 30 minute focus blocks, short and long breaks, and keep the screen visually calm with skyline backgrounds from Bangalore, Tokyo, San Francisco, New York, Singapore and soft European cityscapes. Pause and resume sessions without losing progress and enable a gentle sound when the timer completes.
Why Client-Side Developer Tools?
No accounts, APIs or data retention. Test configurations safely in your browser, copy validated results, and integrate directly into scripts, Dockerfiles or infrastructure-as-code templates while keeping sensitive data local.
Developer Tools FAQs
Format with indentation, validate structure, parse arrays to simple tables, minify for production, export to CSV, and copy or download clean results. Handles nested objects using dot notation keys.
Yes – all processing happens 100% in your browser. JSON, cron strings and Pomodoro usage are never sent to a server, so you can test sensitive data safely.
Yes, export any JSON array to CSV with automatic headers. Nested objects flatten to dotted keys (user.name, user.email) so that Excel and Google Sheets can read them easily.
It uses the standard 5-field Unix cron format: minute (0–59), hour (0–23), day of month (1–31), month (1–12) and day of week (0–7). This works with Linux crontab, many CI tools and common cloud schedulers.
Choose 25 or 30 minute focus, click Start and work on a single task until the timer ends. Then take a short break and repeat. After a few cycles, use the long break option. You can change wallpapers to keep the background calm while you study or code.
