FAQ

Is my JSON uploaded?

No. Validation runs locally in your browser.

JSON Schema Validator: Can I use the result in production?

Treat generated, converted, or inspected output as a development aid. Validate security-sensitive values, commands, and configuration in the target environment before production use.

Does JSON Schema Validator upload my input?

TrueFree Tools processes the input in your browser and does not store it on our servers. Features that need browser permissions or access to a user-supplied address still follow the notice shown in the tool.
