What JSON Visualizer does

JSON Visualizer is a browser-based tool that converts raw JSON code into an interactive, collapsible tree structure. Users paste their data into the input area and receive a graphical representation with color-coded nodes for strings, numbers, booleans, and nulls. The output includes utility features such as a search function to locate specific keys or values, the ability to copy JSON paths or data from any node, and statistics displaying key count, nesting depth, and type distribution. The entire process occurs within the user's browser, ensuring that no data is transmitted externally.
