Frequently Asked Questions
What is the difference from JSON Visualizer?
The JSON Visualizer is for general JSON exploration. API Response Explorer is optimized for API responses — it collapses long arrays by default, shows array sizes, and has API-specific stats.
Can I explore deeply nested responses?
Yes. The tree view handles any depth of nesting. Use Collapse All to start from the top and expand only the parts you need.
Can I use this with non-API JSON?
Absolutely. It works with any valid JSON - configuration files, data dumps, or API responses.
Is the data uploaded?
No. All processing happens locally in your browser using JavaScript. Your data never leaves your device.
