CodePrettify turns raw JSON, JavaScript, CSS, XML, RSS, YAML, TOML, CSV, and Markdown into a readable, searchable workspace. Format and validate content, navigate large files with tree view and breadcrumbs, run JSONPath queries, compare documents, repair malformed JSON, convert formats, decode JWT and Base64, and generate typed code.
Everything runs locally in your browser or Windows app—no telemetry, cloud upload, or external processing. It is free and built for developers, testers, analysts, and support teams who regularly inspect API responses and data files.
