Frequently Asked Questions
Is this JSON formatter free?
Yes, completely free! No hidden costs, no registration. Format,
validate, and convert unlimited JSON.
Is my data stored?
No. All processing happens locally in your browser. We do not upload
or store any JSON data on our servers. Your privacy is fully
protected.
What JSON formats are supported?
We support standard JSON (RFC 8259), JSON with comments, JSON5, and
JSON Lines. The validator checks for strict compliance.
Can I convert JSON to other formats?
Yes! Convert JSON to YAML, XML, CSV, and TOML. Use the "Conversion
Tools" tab to try different formats.
What is JSON Schema validation?
JSON Schema allows you to define the structure, required fields, and
data types your JSON must follow. It's like a blueprint for your
data.
Does it work with large JSON files?
Yes, but performance depends on your browser. For very large files
(>10MB), we recommend using the minify option first to reduce size.
