Raw JSON responses, minified scripts, configs and feed files are difficult to read, validate, compare and turn into useful code. Most workflows require juggling multiple tools and sending sensitive payloads to third parties. CodePrettify brings formatting, validation, repair, inspection, generation and export together locally in a browser extension and Windows app.
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.
