Turn labelled text into checked JSON

Paste a JSON Schema and text with labelled values, such as "Invoice number: INV-42", or a CSV header and row. SchemaBud fills the fields it can match, converts numbers exactly, leaves the rest empty, and validates the result. Every value shows the line it came from.

Schemas can't use "pattern" or "format", and only local "$ref" values work. Input is processed in memory on the server and is not stored or logged.
