What is JSONLint?

JSONLint checks whether your JSON is valid, points to the line with the error and reformats it into readable, indented code. It is free in the browser and also offers tools to minify, compare and convert JSON to and from CSV and YAML.

Pros: what JSONLint does well

  • Clear error messages
  • Format and minify in one place
  • Extra JSON converters

Cons: where it falls short

  • Ads on the site
  • Avoid pasting sensitive data

Who JSONLint is for

Developers who need to check or tidy JSON quickly.

Who can skip it

People who never work with data files or APIs.
