Frequently Asked Questions (FAQs)

What does "Case Insensitive Comparison" mean?

By default, the tool treats "Apple" and "apple" as two different words. If you check "Case Insensitive", the tool will consider them duplicates and only keep the first one it finds.

Is there a limit to how many lines I can clean?

There is no strict limit! Because the tool runs on your device's memory (RAM), you can easily process lists with hundreds of thousands of lines without any lag or freezing.

Why do I need to remove empty lines?

When copying text from PDFs or web pages, hidden empty lines are often included. Removing them ensures your data is continuous, which is essential when importing lists into Excel, CRM software, or email marketing tools.
