JSON Formatter

This is an entirely client-side tool that formats JSON with whitespace and indentation. Your data does not hit our servers, and so remains completely confidential and GDPR compliant (check Web Inspector to verify if you like!)

What is JSON?

JSON (JavaScript Object Notation) is a lightweight format commonly used for transfering data in web applications. It's relatively compact and easy to read, and is easy for machines to manipulate and parse. JSON is language independent, and is supported by all modern programming languages, but is especially suited to web-based applications.

How does this tool work?

This tool formats complete JSON documents using a standard indented format. It only works with valid JSON documents with some minor extensions: you may include standard JavaScript commas and trailing commas in the source document, though they will be stripped out of the formatted document.
