Common questions
How does JSON Formatter work?
All processing happens in your browser tab—no server round-trips, no hidden logging, and no throttling.
Can I trust the output for production?
Every tool is intentionally minimal, runs client-side, and is tested against common SEO and growth workflows. Validate critical data before publishing.
Will this tool stay free?
Yes. The core library remains free to use. Future subscription tiers will only unlock premium batching or API endpoints.
