JSON-Tool
JSON-Tool is a browser extension designed to facilitate the viewing and manipulation of JSON data. It automatically renders JSON files and addresses—whether accessed online or as local files—into a searchable tree structure, making it easier for users to navigate and interpret complex data. The tool is accessible as an extension for Chrome, Edge, and Firefox browsers, and offers both stable and nightly build releases.
Beyond automatic rendering, JSON-Tool provides features for manual entry of JSON text and the ability to upload JSON files for inspection. It includes utilities that allow users to copy specific keys, paths, and values from JSON objects, as well as perform text compression, URI encoding and decoding, base64 operations, and timestamp conversion. To accommodate user preferences, the extension supports theme customization, including dark mode and custom color schemes.
JSON-Tool is positioned as a utility for users who work with JSON data in their browsers, providing tools for both analysis and transformation of JSON content.
