marabesi/json-tool ? reverse-engineered prompt

Build me a privacy first JSON tool that runs entirely on my machine, so I can paste in JSON, format it, and move on without sending anything to a website.

I want it to validate the JSON too, and show a clear error when the input is invalid. It should have easy buttons for paste and copy, support uploading a JSON file, and let me search through the content. I also want a few different ways to view the data, including a normal formatted view plus more visual views like table and shape style browsing. The editor panels should be resizable, either by dragging or with the keyboard, and the controls can stay simple with icons and tooltips.

Make it feel fast and clean, and if you need to look up current docs online while building it, go ahead.
