Clean up lines
When you are working with lists — email addresses, keywords, URLs, names or log entries — the same line often appears more than once. Spotting and deleting duplicates by hand is slow and easy to get wrong. This tool removes duplicate lines instantly, keeping the first time each line appears and preserving the original order of your list.
Two lines are treated as duplicates when their content is the same, ignoring extra spaces at the start or end. The first occurrence is kept and every later copy is removed. Blank lines that repeat are collapsed too, so your list ends up clean and compact.
De-duplicating email or subscriber lists, cleaning keyword and hashtag lists for SEO and social media, tidying URLs before a crawl, removing repeated rows pasted from spreadsheets, and cleaning log files. If your lines also have messy spacing, tap "Clean extra spaces" first for the best result.
Does it change the order? No — the remaining lines stay in the order they first appeared. Is it case-sensitive? Yes, "Apple" and "apple" are treated as different lines. Is my data private? Completely — the tool runs in your browser and nothing is uploaded.
Tidying a list? Pair this with remove extra spaces to fix messy spacing first, then use the word counter to check how many unique lines you ended up with. Everything runs privately in your browser.
