How to clean up pasted text
Trim whitespace, remove empty or duplicate lines, collapse repeated spaces, convert tabs to spaces, and sort lines A-Z or Z-A, all in one pass.
Trimming vs. removing trailing whitespace
"Trim each line" removes whitespace from both the start and end of every line. "Remove trailing whitespace only" removes it from the end alone, which keeps leading indentation intact, useful when cleaning up code without breaking it.
Removing duplicates and empty lines
Removing duplicate lines keeps only the first occurrence of each exact line and drops the rest, in their original order. Removing empty lines drops any line that is blank or contains only whitespace.
How to use it
- Paste text, or drop a text file, into the input box.
- Check any combination of clean-up options; the result updates as you go.
- Optionally sort the result A-Z or Z-A.
- Choose Copy to copy the cleaned result.
Local processing
Every clean-up step runs on the text already in your browser. Nothing you paste or drop is sent to a ProntoUso server.
Text cleaner FAQ
- What's the difference between the two whitespace options?
- "Trim each line" removes whitespace from both ends. "Remove trailing whitespace only" removes it only from the end, preserving leading indentation, which matters for code or nested lists.
- In what order are the options applied?
- Tabs convert to spaces first, then whitespace trimming, then space collapsing, then empty and duplicate lines are removed, and sorting runs last. This order gives the most predictable result when several options are combined.
- Does sorting use my language's alphabetical order?
- Yes, it uses your browser's locale-aware comparison, so accented letters sort where you'd expect.
- Is my text uploaded anywhere?
- No. Every option runs locally in your browser.
