About JSON Viewer / Tree Editor
This tool displays JSON data as an interactive tree instead of a flat wall of text — click any object or array to collapse or expand it, so you can focus on the part of a large JSON structure you actually care about. You can also double-click any value to edit it directly, then copy or download the updated JSON. All processing happens locally in your browser; your data is never uploaded to a server.
Tips for Using the Tree View
Use Collapse All first on a large JSON file to get an overview of its top-level structure, then expand only the branches you need — this is usually faster than scrolling through everything expanded. The search box highlights any key or value that matches what you type and automatically expands its parent branches, so you can jump straight to a specific field even in deeply nested data. When editing a value, type it exactly as valid JSON — strings need quotes (like "example"), while numbers, true, false, and null should be typed without quotes; an invalid entry will be rejected rather than silently corrupting your data.
