Working with JSON data often means opening files that are difficult to read in raw form. Our JSON Reader Online Tool helps you open, view, and explore JSON files instantly, making structured data easy to navigate, analyze, and understand.
A JSON Reader is an online tool that allows you to open JSON files, parse data, and explore key-value pairs in a human-readable format.
JSON (JavaScript Object Notation) is widely used in:
package.json
, tsconfig.json
)However, raw JSON is often minified (compressed), making it hard to read. A JSON Reader displays the data in a formatted, tree-view structure, so you can navigate through objects and arrays easily.

When working with JSON data, a simple text editor isn’t enough. Here’s why a dedicated JSON Reader tool is essential:
.json
file.{"id":1,"name":"John Doe","email":"john@example.com","role":"admin","permissions":{"read":true,"write":false,"delete":false}}
{
"id": 1,
"name": "John Doe",
"email": "john@example.com",
"role": "admin",
"permissions": {
"read": true,
"write": false,
"delete": false
}
}
