Frequently Asked Questions

What does "Case-sensitive" mean?

When enabled, the tool will treat "Apple" and "apple" as different lines. When disabled, they'll be considered the same and duplicates will be removed.

Can I undo the processing?

The tool doesn't have an undo feature, but your original text remains in the input area until you clear it or paste new content.

Is there a limit to the text size?

There's no fixed limit, but very large texts (over 100,000 lines) may slow down processing in some browsers.

What file format is used for download?

The download feature saves your processed text as a standard .txt file with UTF-8 encoding.

Does this tool work offline?

Yes! Once loaded in your browser, this tool works completely offline with no server-side processing required.
