    JSON Formatter

    A JSON formatter is a tool that takes raw JSON data and makes it readable by adding indentation, line breaks, and consistent spacing. This free formatter validates your JSON as it formats, flagging syntax errors like missing commas or unmatched braces, and can also minify JSON into a compact single line, entirely in your browser.

    How to format JSON online

    1. Paste your raw or minified JSON into the input field.
    2. Choose Prettify to make it readable or Minify to compress it.
    3. If the JSON is invalid, read the error message to find and fix the syntax problem.
    4. Copy the formatted result back into your code, API request, or config file.

    Frequently Asked Questions

    What does a JSON formatter do?

    A JSON formatter improves the readability of JSON data by adding proper indentation, line breaks, and spacing. It can also help identify syntax errors in your JSON structure that might be causing parsing issues.

    Why would I need to format JSON?

    Formatted JSON is much easier to read and understand, especially for complex nested structures. This makes debugging, editing, and analyzing JSON data more efficient. Clean formatting also makes it easier to identify structure and relationships in your data.

    What's the difference between minify and prettify?

    Prettify adds whitespace, indentation, and line breaks to make JSON human-readable. Minify does the opposite: it removes all unnecessary whitespace to create a compact, single-line version that's more efficient for file storage and transmission.

    Is the JSON formatter secure?

    Yes, our JSON formatter processes all data directly in your browser. Your JSON data never leaves your computer or gets sent to any server. This ensures complete privacy and security for sensitive data.

    What are the common JSON syntax errors?

    Common JSON syntax errors include missing commas between elements, using single quotes instead of double quotes, trailing commas at the end of lists, unquoted property names, and unmatched brackets or braces. Our formatter helps identify these errors.
