What is the safest order for cleaning a list?
First fix obvious whitespace and empty-line problems, then remove duplicates, and sort only after you are sure order is not meaningful. This makes it easier to notice what each operation changed.

How to remove extra spaces and duplicate lines from text on iPhone
Clean copied text on iPhone by fixing whitespace, removing duplicate lines, sorting lists, and previewing the result before copying, sharing, or saving a new TXT file.
Quick answer
The shortest useful answer
For messy copied text, treat whitespace cleanup and duplicate-line removal as separate operations. Text Tools DOKUNTAG keeps the source and live preview visible, so you can apply a cleanup step, inspect the result, then copy, share, or save a new TXT file without overwriting the source.
How to
Step by step
- Paste or type the text, or open a supported TXT file.
- Use the Edit tools to normalize messy whitespace and empty lines as needed.
- Use the Lines tools to remove duplicates or sort the list.
- Compare the source and live preview, then copy, share, or save a new TXT result.
Can you change only selected text?
Yes. In Text Tools DOKUNTAG, selecting a range in the preview scopes the next supported transformation to that selection. With no selection, the operation applies to the whole text.
Does the text need an internet connection?
No. The locked core Text Tools workflow is offline, accountless, ad-free, and tracking-free. The source TXT file is never silently overwritten; saving creates a new result.
