PasteKit is a browser-based formatter and converter: paste on the left, and it detects the format and pretty-prints on the right in milliseconds. It covers JSON, JSON5, YAML, XML, CSV, TSV, TOML, SQL, HTML, Markdown, CSS, JavaScript, TypeScript, GraphQL, Dockerfile, Nginx and Apache configs and more.
Its pitch is privacy: format anything, upload nothing - your data never leaves the browser. The interface ships in nine languages with light and dark themes.
