How to use Python Code Cleaner

Paste your Python code, and the tool converts tabs to spaces, trims trailing whitespace, and tidies up blank lines.

Frequently asked questions

What does this tool do?

It normalises Python whitespace — converts tabs to 4 spaces, removes trailing whitespace on each line, and collapses runs of blank lines to at most two (PEP8's maximum).

Does it re-indent or reformat my code?

No. Python's indentation is meaningful, so re-deriving it could change what your code does. This tool only normalises whitespace it can safely touch. For full auto-formatting, run Black or autopep8 locally.

Why convert tabs to spaces?

Mixing tabs and spaces is a common cause of Python IndentationErrors. PEP8 recommends 4 spaces per indent level, so this tool standardises on that.
