JSON Parser Online

Check whether a document follows JSON syntax. Valid input produces formatted output; invalid input shows a parsing error.

Paste the document you want to check, then select Parse JSON.

Value kind

Not parsed

Check punctuation and quotes

Property names and strings need double quotes. Missing commas, unmatched brackets, and incomplete values prevent the document from parsing.

Syntax is not a schema check

A successful parse means the text is valid JSON. It does not confirm that required fields are present or that values meet the requirements of your application.

Fix errors in the input

Use the error message to review your input, then parse again. The tool does not repair malformed JSON or accept comments and trailing commas.
