JSON Parser FAQ
What is JSON?
JSON (JavaScript Object Notation) is a lightweight data-interchange format. It is easy for humans to read and write and easy for machines to parse and generate.
Why is my JSON invalid?
Common errors include trailing commas, using single quotes instead of double quotes for keys and string values, or unescaped characters within strings.
What is the difference between an object and an array in JSON?
An object is an unordered set of key/value pairs enclosed in curly braces `{}`. An array is an ordered list of values enclosed in square brackets `[]`.
How does the error highlighting work?
When our parser detects invalid JSON, it analyzes the error message to find the exact character position. It then automatically focuses the input field and highlights the problematic character, helping you debug syntax errors instantly.
Is my data safe with this online tool?
Absolutely. Your privacy is our priority. All parsing and validation happen directly in your browser. No data is ever sent to or stored on our servers.
