Online Json Structurer Online — Frequently Asked Questions
Got questions about Online Json Structurer Online? Here are clear, honest answers to the most common questions about pricing, privacy, compatibility, and features.
Is it safe to paste API keys or JWT tokens into Online Json Structurer Online?
Yes. Unlike other developer tools that send data to a central server for processing, 30tools executes all logic locally in your browser. Your sensitive tokens are never sent over the internet.

We use optimized parsing algorithms that can handle payloads up to 10MB without freezing your browser. For even larger files, our 'Large File Sorter' is recommended.

Yes. Once the page is loaded, the tool's core logic resides in your browser cache, allowing you to perform transformations without an active internet connection.
Does this tool support minification?
Many of our developer tools offer both 'Pretty Print' (for readability) and 'Minify' (for production use) options to suit your specific workflow.
Are there any API limits?
No. Since the tool runs on your hardware, there are no rate limits, no daily caps, and no need for an API key.
What character encodings are supported?
We fully support UTF-8, UTF-16, and various Base64 variants (Standard and URL-safe).

To maximize privacy, we do not store your data. However, your most recent settings are often preserved in your browser's local storage for your convenience.
