CodePrettify is a free browser extension and Windows app that turns raw JSON, code, configuration files, documentation and feeds into a searchable, foldable developer workspace. Format, validate, repair and transform JSON; query JSONPath; compare revisions; generate typed models; visualize structure as diagrams; inspect secrets and endpoints; create HTTP requests; and export results. It supports JavaScript/TypeScript, JSON/JSONC/JSON Lines, Markdown, XML/RSS/Atom, YAML, TOML and CSS in the extension, plus CSV and HTML in the Windows app. Processing stays local—no account or document uploads.
