A focused json to json schema workflow.
Infer a Draft 2020-12 JSON Schema from representative data. XXF runs the transformation in your browser so sensitive API payloads, tokens, configuration and source text do not need to cross the network.
How to use JSON to JSON Schema
- Paste sample json into the left editor or load the realistic sample.
- Select Generate schema or press Command/Ctrl + Enter.
- Copy the output to your project, or download it as a
.schema.jsonfile.
When this tool helps
Use it while debugging API responses, preparing fixtures, translating configuration, documenting integrations or moving data between frontend libraries. The dedicated output panel keeps the source untouched, which makes comparison and retrying safer.
Accuracy and safety notes
Generated code and schemas are starting points derived from the sample you provide. Review domain rules, optional values and security-sensitive behavior before shipping. For credentials or customer data, local processing reduces exposure but your own device and browser still need to be trusted.
Frequently asked questions
Does XXF upload or store my data?+
No. The conversion runs locally in your browser. Your input is not sent to XXF, stored on a server or used for training.
Which JSON Schema version is generated?+
The output declares JSON Schema Draft 2020-12 and can be extended with formats, ranges and descriptions.
