What is json.minify?

JSON Minify is a tool that cleans up JSON files by stripping out comments and extra whitespace, leaving behind compact, valid JSON that any standard parser can read. The core benefit is simple: you get to write and maintain JSON files with helpful comments and readable formatting during development, then strip all that out before the data is actually used or sent anywhere. JSON is a popular format for storing and exchanging data, but the official standard doesn't support comments. That means if you add notes to your JSON file to explain what each field does, standard parsers will reject it. This tool solves that problem by acting as a middle step. You feed it your human-friendly, commented JSON, and it hands back a compressed, comment-free version that won't cause errors. Anyone who works with configuration files or data files in JSON format would find this useful. For example, a team might have a large JSON settings file where developers add comments explaining each option. They can keep that readable version in their codebase, then run it through the tool before sending the data from a server to a browser, keeping network transfers small and avoiding parse errors. The project originally launched as a JavaScript library, but it has since been adapted for several other programming languages, including PHP, Python, and Objective C. The different versions are organized into separate branches within the same repository, so you can find the one that matches your technology stack. The README references a historical discussion about why JSON doesn't officially include comments, which provides context for why a separate cleanup tool is needed rather than just expecting parsers to handle it natively.
