Developer Snippet Cleaner
Clean copied code, config, and markdown lines without leaving your browser.
Clean pasted developer text
Developer snippets often arrive with duplicated lines, extra indentation, blank rows, or formatting that is awkward to paste into docs. This cleaner turns that pasted text into a predictable output: trim environment variables, dedupe copied headers, sort a list of config keys, or add markdown bullets to release-note lines.
For example, paste a copied env sample, choose trim and dedupe, and the repeated `API_URL` line disappears while the remaining keys stay easy to read. The prefix mode is useful when turning plain lines into checklist items, and wrap mode helps prepare small fixture lists without opening a heavier editor.
Local text cleanup
The tool treats your input as plain text and runs entirely in the browser. It does not validate secrets, parse language syntax, or contact a formatter service. Before pasting the result into a project, scan it once for meaningful order, comments, and values that should stay private.
Frequently Asked Questions
What can this snippet cleaner fix?
It can trim pasted lines, remove empty rows, dedupe repeated lines, sort a list, add prefixes, and wrap each line for quick documentation or config cleanup.
When should I use each cleanup mode?
Use trim and dedupe for copied logs or lists, sort for environment keys, prefix for markdown bullets, and wrap for turning values into quoted strings.
Will it validate code syntax?
No. It cleans text predictably, but it does not understand every programming language or validate that a config file is safe to run.
Is pasted code sent to a server?
No. The snippet cleaner runs locally in your browser and only copies the text already visible in the output panel.
