Frequently Asked Questions
Is my JSON data safe?
Yes, absolutely. This tool runs entirely in your web browser using JavaScript. No data is sent to our servers, making it safe for confidential or sensitive information.
How do I handle nested JSON objects?
By default, our tool enables "Flatten Object" mode. This converts nested structures (like {"user": {"name": "John"}}) into dot-notation columns (e.g., user.name). You can convert complex API responses directly into flat spreadsheets.
Can I convert large JSON files?
Yes. Since the processing is done locally on your device, the limit depends primarily on your computer's memory (RAM). Most modern browsers can easily handle files up to 100MB+ instantly.
