Power JSON Editor lets you edit JSON in WYSIWYG mode, inspect the JSON hierarchy in a tree view, search with JSONPath and move nodes around with a few keystrokes.

It also ships with plugins for many JSON-related jobs, and its format converter plugins turn files into and out of JSON, Plist, YAML and TOML.

More about Power JSON Editor

You can edit a JSON file in the raw text view or in the tree view. The two panels stay in sync: a change in one shows up in the other right away.

The text editor has syntax highlighting, formatting and a parse error indicator. Plugins add more: the Local Web Server plugin serves the files you are editing over HTTP so other apps can fetch them, which works like an API mock server, and the Scripts plugin runs any JavaScript file against your JSON.

More editor features:

Parse error messages that help you debug invalid JSON
One-click beautify and compact
Convert a node between string, number, boolean and null
Duplicate, cut, copy and paste nodes
Change a node’s parent with Command+] or Command+[
Wrap a node in an object or array
Drag and drop JSON between documents or other editors

JSONPath support

Power JSON Editor can filter nodes with JSONPath since version 1.3.0. Script expressions such as (@.length-1) are not supported.

Filter expressions

Filter expressions look like ?(price < 10).

Operator type	Operators
String comparison	`=`, `contains`
Number comparison	`=`, `<`, `>`, `<=`, `>=`
Collection	`field in {value1, value2}`
Logic	`and`, `or`

Examples

All books cheaper than 10: $..book[?(price<10)]
All books whose title contains “of”: $..book[?(title contains 'of')]
All books priced 8.95 or 8.99: $..book[?(price in {8.95, 8.99})]

Render template example

The JSON Template Render plugin renders your data with a Jade template:

- each item in data
    h2= item.title
    p= item.text

PJEPlugIn = {
    // Name of this plugin, will show in submenu of Scripts plugin menu
    name: "Sample: Parse JSON with Comments",
    /**

     @param json    JSON object from editor, maybe null for inform JSON
     @param jsonStr JSON text from editor
     @return Return value can be any valid JavaScript object, string will be treated as JSON text

    func: function(json, jsonStr) {
        return eval('(' + jsonStr + ')');
    }
};
