JSONView: A Chrome Extension for Viewing JSON Documents

JSONView is a unique browser extension specifically designed for Chrome users. It significantly enhances the way JSON documents are viewed by transforming plain text into a more readable format. The tool stands out by formatting and highlighting JSON documents, allowing the arrays and objects within them to be collapsed for a simpler, streamlined experience. Even in case of errors in the JSON document, this agile extension will show the raw text. An essential tool for those who regularly work with JSON documents.

Extension summary

Analyze keywords

Normally when encountering a JSON document (content type "application/json"), the browser simply shows plain text. With the JSONView extension, JSON documents are formatted, highlighted, and arrays and objects can be collapsed. Even if the JSON document contains errors, JSONView will still show the raw text. Once you've got JSONView installed, check out http://jsonview.com/example.json to see the extension in action!
