JSON Editor Online is a web-based tool to view, edit, format, repair, compare, query, transform, validate, and share your JSON data.
JSON Editor Online is a versatile, high quality tool to edit and process your JSON data. It is one of the best and most popular tools around, has a high user satisfaction, and is completely free. The editor offers all your need in one place: from formatting and beautifying your JSON data to comparing JSON documents or querying your JSON data. JSON is the most used data format between servers and browser, and JSON Editor Online is an indispensable tool for frontend and backend developers working with JSON data in their daily life.
JSON Editor Online is developed and maintained by Jos de Jong, an enthusiastic, passionate senior software engineer with 20+ years of experience in the field. Jos created the editor out of personal needs, working with JSON based API's and databases on a daily basis as a full-stack engineer.
JSON Editor Online offers the following features:
Current version: 6.16.0

editorRight, and you can access the JSON utility libraries
immutable-json-patch in the Developer Console. Just open your Developer Console via
Ctrl+Shift+I and follow the instructions there.
JSON Editor Online just promoted to a fully capable CSV editor. The editor already had a powerful
table view and could export to CSV. Now you can also import CSV, making the CSV support complete.

Copy and paste your JSON file in the JSON editor, or load it from disk via the menu or via drag-and-drop.

You can learn more in the Documentation.
You can use the editor as a json formatter. In code mode, you can paste a JSON file in the editor, and click the "Format" button from the menu.

Format JSON is the same as beautify JSON : you make your JSON file readable by styling it with white spacing, newlines, and indentation. In short: paste your JSON file, then click the "Format" button in code mode, or select "Copy formatted" from the menu. This is how you make your JSON pretty. Read more.

A JSON validator verifies whether your JSON document adheres to the JSON specification. On top of this, you can use a JSON schema validator to validate whether the contents of your document adheres to a specified schema.
Beautifying JSON is neatly formatting its contents with indentation and new lines to make it better readable. Software developers often validate JSON and then format it in one go in order to inspect the document.
Using an online JSON editor is useful for validating, repairing, formatting, and querying JSON data on the fly. When working with JSON configuration files in a project though, it may be handier to use your own IDE. There are various categories of JSON tools, each with their pros and cons. What is best to use depends on your use case.
