What Is JSON?
JSON (JavaScript Object Notation) is a lightweight text format for storing and exchanging data. It uses key-value pairs (like a dictionary) and arrays (like a list). It's the standard format for web APIs and configuration files.
What Does "Parsing JSON" Mean?
Parsing converts raw JSON text into a structured data representation. When you parse {"name":"John","age":30}, the parser creates an object where you can access object.name to get "John".
How to Parse JSON Online
- Open JSON Parser Online.
- Paste or type your JSON string into the input box.
- Click Parse (or it parses automatically as you type).
- The structured tree view shows your parsed data.
- Expand/collapse nodes to explore nested objects and arrays.
Validating JSON
A JSON parser will show errors for invalid JSON. Common errors: missing commas between key-value pairs, trailing commas after the last element, using single quotes instead of double quotes, or unescaped special characters in strings.
