JSON Formatter and Validator

Format JSON, inspect syntax errors and produce compact JSON without sending configuration or API data to a server.

Files stay in this browser tab.

How to use it

Paste a JSON document and select formatting or compact output. Correct the reported syntax error if parsing fails.

Worked example

{"service":"inventory","replicas":2,"enabled":true}

What to check

JSON formatting checks syntax, not application-specific rules. Avoid sharing real credentials in examples.

Build a system for this use case

API development workstation

Example OpenFactory build prompt

Build a useful api development workstation on Ubuntu 24.04 LTS amd64, unless the target installer or embedded board requires its explicitly selected OS.

Use Node.js, Python, jq, a local sample API and JSON schema validation. Include only the components this workload needs. Use synthetic sample data and placeholders for site-specific domains, authorized SSH public keys and external integration credentials. Create a non-root operator and keep administrative access private. Never put real credentials, patient records or customer data in the image.

Acceptance checks: run the API, validate example responses, reject malformed JSON and start the development service after reboot. Boot the actual artifact and repeat relevant health, persistence and access checks after reboot. Keep hardware-dependent checks pending until the specified equipment is attached.

Deliver the bootable image or reproducible deployment recipe, the software inventory and a test report that separates successful assembly from runtime verification. Ask for missing hardware, storage and access details before making irreversible deployment choices. Do not deploy into production or erase an existing disk without an explicit target.
