Live editor for JSON documents

Little online and offline HTML, CSS and JavaScript code editor for messing around with JSON documents. For example, this tool will be useful if you want to manipulate and display JSON data outputted by a REST API. The editor will be activated automatically in the browser if a JSON document is detected (e.g. with http://jsondoc.eu01.aws.af.cm/api/jsondoc). Features : * HTML / CSS / JavaScript editor with syntax highlighting, search, replace and autocomplete * Live code preview * Drop code from File System * Save code to File System * Versioning using browser’s history and local storage * Easy sharing via URL * JSON Validator (invalid JSON is not editable) * Key shortcuts: - cmd + s / ctrl + s => live update / save - cmd + e / ctrl + e => toggle preview / code editor - ctrl + space => autocomplete - cmd + f / ctrl + f => search and highlight code - cmd + g / ctrl + g => find next - shift + cmd + g / shift + ctrl + g => find previous - shift + ctrl + f / cmd + option + f => replace - shift + ctrl + r / shift + cmd + option + f => replace all (Note: this extension might clash with other JSON highlighters/beautifiers, like ‘JSONView’, ‘Pretty JSON’ or ‘Sight’ – disable those before trying this). Credits go to Mrdoob, Callum Locke and CodeMirror folks.

For file// links, shows the HTML for some reason, doesn't work on online JSON stuff that doesn't identify itself as JSON content type
