JSON (File) Inspector

Utility to investigate unfamiliar JSON files. The software will list and enumerate keys, and show structure in different ways.


JSON Inspector is a one-page PHP Utility that allows you to upload and analyze a file in JSON format. It uses standard PHP, HTML, CSS and has no dependencies to third-parties.


A web server that supports PHP (> 5.6), and a browser.


Getting Started

Download the file. Then, rename the file, removing the ".txt" extension so that the file name ends in ".php".

Next, upload the PHP file to a web server, and enter the URL in a browser. Now you can select a file on your hard drive to inspect.


To uninstall the software, just delete the software file. It's easy.
