About JSON Formatters Pro

Empowering Developers with Professional JSON Tools

Our Mission

JSON Formatters Pro is dedicated to providing developers, data scientists, and JSON enthusiasts with the most powerful, secure, and user-friendly JSON tools available online. We believe that working with JSON should be simple, fast, and accessible to everyone—without compromising on features or security.

Built by a Developer, for Developers

JSON Formatter Pro is built and maintained by Faisal Ahmad, an independent software engineer passionate about creating tools that solve real problems.

Why I built this: As a developer working with APIs and data pipelines, I constantly faced issues with existing JSON formatters. Most tools failed when handling Python dictionaries with single quotes, couldn't fix trailing commas, or struggled with large files. I wanted something better.

  • Single Quote to Double Quote: Automatically converts Python dict output to valid JSON
  • Trailing Comma Fix: Removes invalid trailing commas that break JSON parsing
  • Large File Support: Handle 10MB+ files with a powerful Monaco editor (same as VS Code)
  • Client-Side History: Your edit history is stored locally, never sent to any server
  • Privacy-First: All processing happens in your browser, your data never leaves your device

This tool is actively maintained with regular updates based on user feedback. Have a feature request? Let me know!
