Cleanor Labs
These sections explain the job in plain language and set expectations for what the tool should do well.
To clean up Markdown, paste your source into the input box and the cleaner normalizes the common spacing problems automatically: inconsistent blank lines between sections, missing spacing around headings, ragged list indentation, uneven fenced code blocks, and trailing whitespace at line ends.
The cleaner is deliberately conservative. It improves readability and consistency without rewriting your words, reordering content, or enforcing an opinionated style guide, so the cleaned output means exactly what the original did. A rendered preview lets you confirm nothing changed before you copy or download it.
All cleanup runs locally in your browser. Your Markdown is never uploaded to a server, so it is safe to tidy private docs, drafts, or internal notes.
A useful Markdown cleaner should improve readability without becoming a style-guide enforcement engine. Aggressive reformatters often surprise you by rewriting links, reflowing paragraphs, or changing list markers, which can introduce real differences in rendered output. This tool avoids that.
By focusing on safe spacing and whitespace cleanup, the cleaner produces output that is easy to diff and review. The next step, whether that is committing the file, exporting it, or comparing versions, stays predictable because the structure and meaning are untouched.
This makes it a good fit before publishing a README, tidying a docs file pasted from another editor, or normalizing Markdown that has drifted out of shape over many edits.
