PasteKit

Format JSON, YAML & SQL privately

PasteKit is a browser-based toolbox for working with text and data. Drop in JSON, YAML, XML, SQL, CSV, or code and get cleanly formatted, validated output right away. It covers 58 formats, 48 converters, and a set of JSON utilities including diff, schema tools, repair, and jq-style queries. Because everything runs locally in your browser and is enforced by a strict Content Security Policy, the content you paste never leaves your machine.
