Frequently Asked Questions
Everything you need to know about removing duplicate lines
How does the duplicate detection work?
The tool compares each line exactly as written (case-sensitive) and removes any lines that appear more than once, keeping only the first occurrence of each unique line.
Does the tool preserve the original order?
Yes, the tool maintains the original order of lines and keeps the first occurrence of each unique line while removing subsequent duplicates.
Is duplicate detection case-sensitive?
Yes, the duplicate detection is case-sensitive. 'Hello' and 'hello' would be considered different lines and both would be kept.
Can I see how many duplicates were removed?
Yes, the tool displays statistics showing the original line count, unique lines remaining, and total number of duplicates removed.
Does the tool handle empty lines?
Yes, empty lines are treated like any other content. If there are multiple empty lines, only the first one will be kept and the rest will be removed as duplicates.
