JSON Pretty Print — Readable JSON in One Click
Pretty-print raw or minified JSON with customizable indentation. Choose tabs or spaces and set your preferred depth for a clean, readable result.
Pretty Printing for Documentation
When embedding JSON examples in technical documentation or blog posts, pretty-printed output with consistent indentation makes samples easier for readers to follow. Many documentation generators (Docusaurus, GitBook, MkDocs) expect well-formatted JSON for proper syntax highlighting in code blocks.
Choosing the Right Indentation Style
Two-space indentation is the JavaScript ecosystem standard and keeps deeply nested objects compact. Four-space indentation aligns with Python and Java conventions and provides more visual separation between levels. Tabs let each developer configure their editor to display the width they prefer. Pick the style that matches your project's existing code and stick with it.
Frequently Asked Questions

By default, key order is preserved. You can enable alphabetical key sorting from the options menu if you prefer deterministic output for diffs and version control.
