How to Edit JSON Visually
- 1
Load Your JSON
Paste raw JSON into the editor, import a.json file from your device, or click Load Sample Data to start with an example structure. - 2
Navigate the Tree
Expand and collapse objects and arrays by clicking their nodes. Use Expand All or Collapse All to control the entire tree at once. - 3
Edit Properties
Click any key or value to edit it inline. Change types using the type selector, add new properties with the plus button, or delete entries with the remove button. - 4
Export Your Changes
Copy the edited JSON to your clipboard or download it as a file. Switch to Raw JSON mode to review the final output before exporting.
Common Use Cases
1
Editing API Responses
Load an API response into the visual editor to restructure fields, rename keys, change values, or remove unnecessary properties before using the data in your application.
2
Modifying Configuration Files
Open JSON config files for tools, frameworks, or deployment systems and make changes through the visual tree without risking syntax errors from manual editing.
3
Building Test Fixtures
Create or modify JSON test data by visually adding objects, arrays, and values. Drag and drop to reorder properties and build complex nested structures quickly.
4
Non-Developer JSON Editing
Allow team members who are not developers to safely edit JSON data using a visual interface that prevents syntax errors and provides clear type controls.
Why Use Visual JSON Editor?
Visual JSON Editor is the tree-and-edit product. Open JSON as a tree, then edit keys, values, and types in place. Drag nodes to reorder. Undo and redo keep a history. Switch to Raw JSON to review the text before you copy or download.
The Visual JSON Editor shows JSON as a tree and lets you edit that tree. Every property is a node. Change types, add children, delete entries, and drag to reorder. Visual mode and Raw JSON mode share the same document.
Use it to inspect and edit API responses, configuration files, and test fixtures. Undo and redo track each change. Copy or download when the tree is correct.
The editor runs in your browser. Pair it with the JSON Formatter, the JSON Schema Validator, and JSON Diff Checker.
How It Compares
Visual JSON Editor is the tree-and-edit product. A read-only tree is not a second editor. Compared to a text editor, the tree view prevents missing commas and unmatched brackets. The type control changes a string to a number or an object without rewriting the parent.
Visual JSON Editor Tips
1
Use the drag handle on any property to reorder items within arrays or rearrange keys in objects without copy-pasting. 2
Click the type icon on any value to convert between string, number, boolean, null, object, and array types instantly. 3
Use Collapse All before editing deeply nested structures to reduce visual clutter and find the section you need faster. 4
The undo/redo history tracks every change, so experiment freely and revert anything that does not look right. 5
Switch between Visual and Raw JSON modes to verify your edits. The raw view shows the exact JSON output that will be exported. Frequently Asked Questions
1
Can I drag and drop to reorder JSON properties?
Yes! Grab the drag handle on any property and drag it to a new position within the same parent object or array. This works for both object keys and array elements.
2
How do I change the type of a JSON value?
Hover over any property and click the type icon button. A dropdown menu will appear letting you convert between string, number, boolean, null, object, and array types. The tool will attempt to preserve the value when converting between compatible types.
3
Is my JSON data sent to a server?
No. Everything runs entirely in your browser. Your JSON data never leaves your device, ensuring complete privacy and security.
4
Can I undo my changes?
Yes! The editor maintains a full undo/redo history. Use the undo and redo buttons in the toolbar, or simply experiment freely knowing you can always go back.
5
How do I add a new property to an object?
Hover over any object or array node and click the plus (+) button. For objects, you'll be prompted to enter a key name and select a type. For arrays, just select the type and a new element will be appended.
6
Can I import JSON from a file?
Yes. Click the Import button to upload a.json file from your device. The tool parses the file and renders it as an interactive tree you can immediately edit.
7
Does this tool validate my JSON?
Yes. When you switch to Raw JSON mode and apply changes, the tool validates the syntax. Invalid JSON triggers an error message with details about the parsing issue.
8
Can I copy or download the edited JSON?
Yes. Use the Copy button to copy the current JSON to your clipboard, or the Download button to save it as a.json file. Both output formatted, valid JSON.
9
What JSON types are supported?
The editor supports all standard JSON types: string, number, boolean, null, object, and array. You can convert any value between these types using the type selector on each node.
10
Is there a size limit for JSON files?
Since processing runs entirely in your browser, the practical limit depends on your device. Most modern browsers handle JSON files up to 5-10 MB comfortably in the tree view.
