JSON Schema Generator

Automate data validation

Hand-written validation is tedious and it drifts. Paste an example and this reads its structure back as a formal schema, which you can then use to catch bad data before it reaches your database or your application logic.

What it is for

• Web scraping. Check that what you scraped matches the shape you expected, so a price is a number rather than a string.
• API development. Describe your request bodies and responses in a format other tools already read.
• Configuration files. Validate a user-supplied config.json before it reaches your code.
