Example input and output
When to use it
Tidy a copied list
Remove empty rows and accidental leading or trailing spaces from notes or a list pasted from another application.
Remove repeated entries
Deduplicate lines after whitespace cleanup while retaining the original order of their first occurrence. Matching is case-sensitive.
What to know before you use it
Cleanup removes blank lines and collapses runs of spaces and tabs. This can change code indentation or carefully aligned text. Duplicate detection is case-sensitive: Apple and apple remain different lines. Keep your original if formatting matters.
Frequently asked questions
What does the text cleaner remove?
It trims each line, replaces runs of spaces and tabs with one space, and removes empty lines. With deduplication enabled, it also removes repeated cleaned lines.
Does it sort the output?
No. It preserves line order. When deduplicating, the first occurrence of each cleaned line is kept.
Can I use it to format code?
It is intended for plain text and lists. It can remove indentation and blank lines that matter in code. Use the JSON formatter for JSON documents.
