contact@jsonreaderonline.comFrequently Asked Questions
Is JSON Reader Online really free?
Yes, completely free. No premium tiers, no feature gates, no hidden charges. Every feature is available to everyone, always.
Is my data safe?
Absolutely. All JSON processing happens in your browser. Your data is never uploaded to any server. We don't use cookies, analytics, or tracking of any kind. See ourprivacy policy for full details.
What's the maximum file size?
Since processing happens in your browser, the limit depends on your device's available memory. Most modern browsers handle files up to 50–100 MB without issues. For very large files, consider using a command-line tool like jq.
Can I use this offline?
Once loaded, the tool works without an internet connection. All processing logic is bundled in the page — no API calls are needed. You can bookmark the tool page for quick access.
I found a bug. What should I do?
Please open an issue on our GitHub repositorywith a description of the problem, the JSON input that caused it, and your browser/OS details. Screenshots are always helpful!
