JSON Visual Editor

JSON Visual Editor

The JSON Visual Editor helps you inspect and edit nested JSON structures in a tree interface. Paste or upload JSON on the left, visualize it on the right, and edit nodes without manually navigating long text blocks. You can switch between tree, view, code, and text modes based on your workflow.

What you can do

• Visualize nested JSON as expandable nodes.
• Edit JSON in tree mode and sync changes back to raw text.
• Validate input before editing.
• Copy and download both source JSON and edited output.
• Work entirely in-browser with no data upload.

How to use

1. Paste JSON in the left editor or upload a file.
2. Click Visualize JSON → Right.
3. Edit nodes on the right in tree mode.
4. Click Apply Visual → Left to update source JSON text.
