What is a JSON Formatter?
A JSON formatter (also called a JSON beautifier or JSON pretty printer) is a tool that takes raw or minified JSON and reformats it with proper indentation and line breaks. The goal is readability — you are transforming existing JSON, not creating new JSON.
A JSON formatter typically also validates the JSON as part of the formatting process. If the JSON is invalid, the formatter will report an error rather than attempting to format it. Try the JSON Formatter & Validator to see this in action.
What is a JSON Editor?
A JSON editor is a tool for writing, modifying, and managing JSON data. Unlike a formatter that just reformats existing JSON, a JSON editor is designed for active editing workflows — creating new JSON objects, changing values, adding or removing keys, and saving the result.
JSON editors usually include features like syntax highlighting, undo/redo history, cursor navigation, file open/save support, and a tree view for exploring complex structures. Visit the JSON Editor to try ours.

| Editing | Basic text input | Full editing with undo/redo |
| File management | Download formatted result | Open, edit, and save files |
| Tree view | Optional output view | Integrated code + tree view |

Frequently Asked Questions
What is the difference between a JSON formatter and a JSON editor?
A JSON formatter takes existing JSON and reformats it with proper indentation for readability — you are not expected to change the content. A JSON editor is a tool for creating, modifying, and saving JSON data — it includes editing capabilities like syntax highlighting, undo/redo, and cursor navigation.
Should I use a JSON formatter or a JSON editor?
Use a JSON formatter when you receive minified or unformatted JSON (from an API response or log) and want to read it. Use a JSON editor when you need to write, modify, or create JSON data. JSONFormatter.site provides both.
Can a JSON formatter edit JSON?
Most JSON formatters allow basic text editing in the input panel, but they are not designed for authoring JSON. A dedicated JSON editor provides a more complete editing experience with undo/redo history, file management, and tree-based editing.
