JSON Lite

Fast JSON viewer - highlights, shows items count/size, handles large files

JSON Lite is a fast and efficient JSON viewer designed for developers and users who need a reliable tool for inspecting JSON and JSONP data. It offers syntax highlighting, collapsible arrays and objects, and convenient features like counting items and properties within JSON collections.

It supports very large JSON files (10MB+) and attempts to display even invalid JSON formats, making it versatile for various use cases. Additional functionalities include quick collapsing of nested structures using keyboard modifiers, preserving original numeric keys order without rounding large numbers, and saving the JSON document in its original format. JSON Lite also enhances your workflow by allowing selection and formatting directly from any page or clipboard content.
