Frequently Asked Questions

Why does raw JSON parsing frequently trigger validation errors?

JSON requires strict formatting rules, including double quotes on all key strings, zero trailing commas, matched braces, and proper unicode character escaping.

Can Checkistan process large database payloads without freezing?

Yes. It uses optimized local memory buffers to safely format and tree-parse large JSON and XML files without causing performance bottlenecks.

Is it safe to format proprietary database records or API payloads here?

Absolutely. Since the formatting, minifying, and conversion engine runs entirely on the client side, your API keys and client records are never exposed.
