Easy JSON QuickLook previews and icon thumbnails.

PreviewJson provides QuickLook file previews and file icon thumbnails for documents encapsulating the popular JSON format. You can view previews with or without JSON object and array markers, choose your preferred level of indentation, the preview presentation font, and the colour of object keys.

The app provides two app extensions: JSON Previewer and JSON Thumbnailer, which can be viewed and managed in macOS’ System Preferences > Extensions. The app itself is a container for these extensions, and is used to set your preferences.

You must run the app first to gain these benefits.

What’s New

Version 1.1.1

• We’ve restored correct indentation: we've restored indentation, period. You spoke, we listened. Now you can choose between indentation (in the original 1, 2, 4 and 8 steps) and the tabulated view introduced in the previous version of PreviewJson. Make your selection in Settings.
• We've fixed a crash experienced by users previewing files containing deeply nested JSON.
