_{Format clipboard JSON, edit and reorganize data in Tree View, edit arrays in Grid View, and extract JSON from logs.}

What Makes It Different

JsonStudio is built for JSON in real development work: API requests and responses, deeply nested data, escaped strings, JSON5-like snippets, and log lines where plain text and JSON are mixed together.

• Local-first: works offline and keeps sensitive JSON on your machine.
• Flexible input: handles standard JSON, JSON5-like snippets, escaped JSON strings, repairable fragments, and mixed log text.
• Visual editing: edit and reorganize data in Tree View, or inspect arrays in Grid View.
• Daily tools in one place: query, diff, convert, validate with schema, and generate typed code.
• Desktop workflow: multi-tabs, file drag-and-drop, format clipboard, shortcuts, unsaved-change prompts, and optional auto-save.

Download

Download the latest installer from GitHub Releases.

Homebrew (macOS)

brew install --cask sundegan/tap/json-studio

macOS

1. Download the DMG for your Mac architecture (aarch64 for Apple Silicon, x64 for Intel).
2. Open the DMG and drag Json Studio.app into Applications.
3. On first launch, if macOS blocks the app because it is from an unidentified developer, right-click Json Studio.app and choose Open, or allow it in System Settings > Privacy & Security.

Current macOS builds are not Apple Developer ID notarized, so the first launch may require manual confirmation.
