About Python Dict Formatter

Our free Python Dict Formatter is a powerful tool for formatting, beautifying, and validating Python dictionary literals. Whether you're debugging, refactoring, or simply trying to read complex nested dictionaries, this tool makes it easy.

Key Features:
  • Format with customizable indentation (2 or 4 spaces, or tabs)
  • Toggle between single and double quotes
  • Sort dictionary keys alphabetically
  • Add or remove trailing commas
  • Minify dictionaries for compact storage
  • Real-time syntax validation
  • Works 100% in your browser for privacy

Simply paste your Python dictionary literal, click Format, and get a beautifully formatted result instantly. Perfect for Python developers, data scientists, and anyone working with Python data structures.

  5. Copy the formatted result to your clipboard.

Frequently Asked Questions

What Python syntax is supported?

This tool supports standard Python dictionary literals including nested dictionaries, lists, strings, numbers, booleans (True/False), and None values. It handles both single and double quotes.

Can I format nested dictionaries and lists?

Yes! The formatter handles arbitrarily nested structures. Dictionaries can contain lists, which can contain more dictionaries, and so on. The formatting is applied recursively to maintain readability.

What's the difference between spaces and tabs for indentation?

Python's PEP 8 style guide recommends 4 spaces for indentation. However, some teams use 2 spaces or tabs. This tool lets you match your project's style. Tabs are more compact but can cause display issues in some editors.

Why would I remove trailing commas?

Trailing commas are allowed and recommended in Python for multi-line dictionaries as they make version control diffs cleaner. However, you might remove them for single-line dictionaries or when working with older Python versions.

Is my data private?

Completely. All processing happens in your browser using JavaScript. Your Python code is never sent to any server, ensuring complete privacy and security for your sensitive data.
