# Visual JSON Editor

View JSON as a tree and edit it in place. Change keys, values, and types. Drag to reorder. Switch to raw JSON when you need the text.

**Use this tool:** [Visual JSON Editor](https://findutils.com/developers/visual-json/)

## Programmatic access

- Browser-only: this tool works on a file, the DOM, or a browser API and has no REST or MCP id.

## 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.

## Visual JSON Editor Tips

- Use the drag handle on any property to reorder items within arrays or rearrange keys in objects without copy-pasting.
- Click the type icon on any value to convert between string, number, boolean, null, object, and array types instantly.
- Use Collapse All before editing deeply nested structures to reduce visual clutter and find the section you need faster.
- The undo/redo history tracks every change, so experiment freely and revert anything that does not look right.
- 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

### 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.

### 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.

### 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.

### 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.

### 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.

### 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.

### 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.

### 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.

### 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.

### 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.
