Normalize Django and Python source with safe whitespace, indentation, blank-line, import, assignment, and URL-layout formatting.

Developer Input

Safe structural formatting

Paste Django or Python source to format

Your code is processed locally in your browser and is not uploaded by this tool.

How to use this developer tool

Paste Django or Python source.
Select a general or Django-specific structural style.
Choose the indentation width.
Format the source and compare changed-line statistics.

What this developer tool does

The formatter applies conservative text transformations for whitespace, imports, blank lines, indentation, assignments, commas, and common function signatures.

Line-ending normalization → trailing-space removal → indentation cleanup → conservative spacing → optional import sorting

This browser-based formatter does not replace Black, Ruff, isort, autopep8, or Python AST-based formatting.

Example

The input products=Product.objects.all() is normalized to products = Product.objects.all().

Tips for better output

Use Standard for general Django files.
Review multiline expressions after formatting.
Run Black or Ruff in the real project for authoritative formatting.
Preserve comments when code contains directives or annotations.

FAQ

Is this Black-compatible?

No. It applies conservative browser-based transformations and does not implement Black's AST rules.

Can it sort imports?

It can alphabetize simple top-level import lines.

Will it change code behavior?

The formatter is designed to avoid semantic changes, but all formatted code should still be reviewed and tested.

Does it support settings.py?

Yes. A settings-oriented mode applies the same safe normalization without evaluating values.

Is code uploaded?

No. Formatting occurs locally in the browser.
