JSON Beautify — Format and Prettify JSON Data

Minified or poorly formatted JSON is nearly impossible to read. The MyPDF JSON Beautify tool formats your JSON with consistent indentation, line breaks, and syntax highlighting, making it easy to inspect and debug.

How to Beautify JSON

1. Paste or upload — Drop a .json file or paste raw JSON text.
2. Format — The tool applies standard indentation (2 or 4 spaces) and validates the syntax.
3. Copy or download — Copy the formatted output or save it as a clean .json file.

What the Tool Does

Feature	Description
Indentation	Consistent 2-space or 4-space indentation
Line breaks	One key-value pair per line
Syntax highlighting	Colour-coded keys, strings, numbers, booleans
Validation	Reports syntax errors with line numbers
Sorting	Optional alphabetical key sorting

Practical Tips

• Use it as a validator. If the tool cannot format the input, the JSON is invalid. Error messages point to the exact line and character where the problem is.
• Sort keys for consistency. Enable alphabetical key sorting to make JSON output deterministic — useful for version-controlled config files.
• Beautify API responses. Paste raw API responses to inspect nested structures and find the data you need.

Can I choose the indentation style?

Yes. Select between 2 spaces, 4 spaces, or tab indentation to match your project's coding standards.

Does beautifying change the data?

No. Beautifying adds only whitespace (spaces, newlines, tabs). The data values, types, and structure remain identical. Use the JSON Minify tool to reverse the process.

Can I beautify JSON with comments (JSONC)?

Standard JSON does not support comments. The tool can strip comments from JSONC input and produce valid JSON output, or flag them as syntax errors depending on your preference.
