If you have performance issues with your JSON files, this tool may be useful. The JSON Viewer from tlio Ornelas and GitHub is a Chrome extension for selecting and printing JSON and JSONP. Not only that, but it also works as an editor, it’s great for the PowerJSON Viewer network to be a free download add-on to your browser, which is ideal because JSONor “JavaScript Object Notation” is most commonly used to transfer data between web applications and web servers. The general problem with computer coding and use is that people, often with such monotonous black and white of stored text, are confused and lost by what they used to do. This is the first problem that JSON Viewer addresses because it allows you to select different types of data in your JSON file. It facilitates coding as the values ​​will be color coded for your convenience. You can adjust the colors and what they should be used for and with everything you can double check the data fairly quickly because you know what to look for. It also has built-in themes that you can use if you don’t want to customize anything. Do you want your background to be easy on the eyes? Dark mode is available in options, (function () {(‘application-page-view-desktop-view’);}); Edit anything you want Anyway, JSON Viewer is more than just a text coloring tool. You can also use it for easy data editing. JSON Viewer has foldable characters, optional clickable URLs, a toggle button to toggle between raw and underlined version, and a notebook where you can enter or paste JSON and format it indefinitely with a button or shortcut. There are also several options that can help you work more efficiently. You can see the line numbers. You can adjust the tab size. You can even include a time stamp and URL header. You can only make mistakes for a real standalone program for the browser extension that goes into your coding so much. What makes this tool even better is that the URLs entered do nothing. JSON Viewer automatically analyzes its content to determine whether it is JSON or not. This eliminates the need to further configure which URL to use for your Bad JSON for a small widget. Despite all these practical features, JSON Viewer still has some failures compared to other similar tools. First of all, it doesn’t fit exactly with other JSON formatting tools, so this add-on can break down and you need to do some inactivation for it to work. Second, local files and anonymous tabs are not automatically included in the JSON data you can work with, so you need to manually enable these options on the Additions page. This is the most important tool for the browser; after all, you can still use it outside the browser. Finally, plugin updates often restore the add-on, so you’ll need to reconfigure it for your specific settings. But on top of that, this is essential for those who constantly work with JSON.
