JSON Viewer
This online JSON viewer displays your data in an interactive tree format, where each node is indented to reflect the data hierarchy. You can expand or collapse any group to focus on the information that matters. Fields and values are color-coded for quick identification, and any change made to the input is instantly reflected in the visualization. Ideal for developers debugging APIs, validating responses, or inspecting configuration files — no installation or sign-up needed.
How It Works
1. Paste Your JSON
Simply paste or drag your raw JSON file into the editor.
2. Instant Verification
The tool quickly validates your code, indicating errors dynamically.
3. Tree Visualization
It generates a fully browsable, color-coded interactive tree for easy data reading.
Common Use Cases
- API Debugging: Understand extensive payload structures by isolating nodes and checking parent-child relationships.
- Configuration Checking: Find missing commas, wrong brackets, or badly structured settings files effortlessly.
- Data Presentation: Share screen easily during technical meetings with a sanitized and collapsible JSON graphic.
Frequently Asked Questions
Is my JSON data saved on the server?
No. The processing happens strictly inside your browser window. We do not transmit or store your JSON objects on our servers, ensuring total privacy.
Can I copy individual parts of the JSON?
Yes. By interacting directly with the generated JSON tree, you can copy specific nodes, arrays, or sub-objects without parsing the entire raw text.
Does the viewer indicate JSON errors?
Yes. If your JSON payload is malformed (missing quotes, trailing commas, etc.), the tool will display a direct red syntax error flag preventing the tree render.
