JSON Viewer
About Tool
JSON (JavaScript Object Notation) is the standard format for data exchange on the web, but raw JSON strings are often minified into a single, unreadable line. This viewer provides a clean, interactive tree structure that makes it easy to explore nested data objects. By allowing you to collapse and expand specific sections, it turns a chaotic wall of text into an organized map of keys and values.
Whether you are debugging a response from a REST API or inspecting a configuration file, this tool helps you visualize the hierarchy of your data. If you find that your JSON is improperly formatted or has syntax errors, you can use the JSON Formatter to fix those issues before viewing. For those working with diverse data types, this utility serves as a companion to the XML Viewer, providing a consistent way to audit structured information.
Interactive Tree Navigation
The "Format & View" action transforms the input into a nested list where you can drill down into arrays and objects. This is particularly useful for complex datasets where a single key might contain dozens of sub-properties. The tool also provides a "Formatted Raw Text Fallback" which gives you a beautified version of the code that you can copy for documentation or code comments, ensuring your peers can also read the data easily.
Handling Invalid JSON
One of the most common frustrations when working with JSON is a missing comma or an unclosed bracket. This viewer includes basic validation logic; if you paste invalid code, it will alert you rather than displaying an empty screen. This immediate feedback allows you to correct the source data before you attempt to integrate it into your application or database.
Features at a Glance
- Collapsible Sections: Toggle visibility on deep objects to focus on the data that matters.
- Tree-Style Viewing: See the parent-child relationships between data points clearly.
- Raw Text Fallback: Get a clean, indented version of the JSON for copying.
- Local Processing: Your data stays in your browser, keeping API keys and sensitive info private.
Frequently Asked Questions
Can I edit the JSON inside the viewer?
This tool is primarily for viewing and inspecting. To make structural changes to the JSON, it is best to use a text editor or a dedicated formatter tool.
Does it support very large JSON files?
Yes, though extremely large files (several megabytes) might take a few seconds to render the interactive tree depending on your device's speed.
Why is my JSON showing an error?
The most common reasons are trailing commas after the last item in a list or using single quotes instead of double quotes around keys and strings.
Is this the same as an XML viewer?
No, JSON and XML are different formats. While they both store structured data, JSON uses braces and brackets, while XML uses tags similar to HTML.
