What is a JSON Parser?
A JSON parser reads raw JSON text and converts it into a structured object your code (or your eyes) can work with, verifying along the way that the text actually conforms to the JSON spec. This tool runs your browser's native parser and shows you the result.
How to use this JSON parser
- Paste your JSON string into the left-hand box.
- Click Parse JSON.
- Valid input is parsed and re-printed cleanly; invalid input shows exactly where parsing failed.
Frequently asked questions
What does it mean to 'parse' JSON?
Parsing JSON means converting a raw JSON text string into an in-memory data structure (objects, arrays, strings, numbers, booleans, null) that a program can work with. In JavaScript, this is what JSON.parse() does.
What happens if my JSON can't be parsed?
You'll see an error message with the exact reason and the line/column where parsing failed, so you can fix the source text.
Is this different from a JSON validator?
A validator only tells you yes/no. This parser actually shows you the parsed, re-serialized structure, which is useful for confirming the data looks the way you expect.
