JSON Viewer: Explore, Search, and Copy JSON Values
JSON Viewer parses JSON and displays it as an interactive, collapsible tree so you can inspect nested data without scanning raw text. Search matches keys or values, while expand and collapse controls show or hide every node. Click a value to copy its path or content, and use type badges to distinguish objects, arrays, strings, numbers, booleans, and null.
JSON Viewer is an online JSON viewer that turns JSON input into an interactive, collapsible tree. Use this JSON tree viewer to explore nested data more comfortably than raw text, and find items with built-in search. It gives developers a quick way to inspect JSON online.
The tool parses your JSON and displays its nodes in a tree. Search filters by key or value, and expand or collapse all controls let you show or hide every node at once. Type badges identify objects, arrays, strings, numbers, booleans, and null. Click a value to copy its path or content.
JSON represents structured data using objects, arrays, and other value types. The viewer does not change the JSON into another format; it presents the parsed structure in a way that is easier to navigate than a block of serialized text. That can help when you need to understand nesting, locate a value, or check its type before working with the data in code.
JSON Viewer runs entirely in your browser. Your input is processed on your device and is not uploaded, stored, or sent to a server. Once the page has loaded, the tool works offline. It is useful for developers and DevOps engineers who want a convenient way to inspect JSON while working with data, configuration, or application output.
Step 1: Paste or drop your JSON into the viewer. The tool parses the input and displays it as a tree.
Step 2: Inspect the parsed tree by expanding and collapsing nodes. Use the controls to expand or collapse every node at once.
Step 3: Search for a key or value to filter the tree and find the data you need.
Step 4: Check the type badge on a node to see whether it is an object, array, string, number, boolean, or null.
Step 5: Click a value to copy its path or content, depending on what you need to use elsewhere.
Use case: Inspect a JSON document you did not write and cannot easily read as raw text. The collapsible tree makes nested data easier to explore.
Use case: Check a value's structure before writing code that consumes it. Type badges help distinguish objects, arrays, strings, numbers, booleans, and null.
Use case: Find a key or value in a JSON document without scanning every line. Search filters the tree to help you locate matching data.
Use case: Copy a clean excerpt from a large or deeply nested document. Click a value to copy its content or path.
Use case: Review JSON configuration data while troubleshooting an application. Expand the relevant nodes and search for the setting you want to inspect.
Use case: Explore an unfamiliar JSON response before deciding how your code should handle its nested values.
