How it helps
JSON can be hard to read when it arrives minified or deeply nested. This tool validates your JSON, formats it for readability, and gives you a tree explorer to inspect keys and values without losing context.
Tips
- Use Beautify to format logs, API responses, or config files.
- Use Minify to shrink payloads before shipping or storing.
- Switch to Tree mode when JSON has multiple nested objects.
Frequently Asked Questions
What does the JSON Viewer do?
It validates JSON, formats it for readability, minifies it for compact payloads, and provides a tree view to inspect nested data.
Is my JSON sent to a server?
No. All formatting and validation runs locally in your browser.
Can it handle large JSON files?
Yes, but very large files may impact browser performance. Minify or split large payloads if needed.
