I Built a Better JSON Formatter for Developers (With Tree View & Error Highlighting)

If you work with APIs daily, you know how painful messy JSON can be.

Most tools either:

• Don’t highlight errors properly
• Struggle with large JSON files
• Or feel outdated

So I built a JSON formatter focused on developers.

Key features:

• Tree view for structured navigation
• Real-time error highlighting
• Handles large JSON responses
• Runs entirely in the browser (secure)

One more thing I focused on was accessibility.

The tool is now available in multiple languages, making it easier for developers worldwide to format and debug JSON without language barriers.

Would love feedback from fellow developers.
