Paste logs, lists, or exports and drop repeated lines. Choose trim-aware matching, case-insensitive comparison, keep first or keep last copy, and optional sorted output. Processing stays on your device — nothing is uploaded to DroidXP.
It scans your text line by line and removes lines that match an earlier (or later, if you choose “last occurrence”) line according to the rules you set. It is useful for cleaning duplicate URLs, email lists, log excerpts, CSV columns pasted as lines, and other one-item-per-line data.
First occurrence keeps the topmost copy and drops later repeats — order of unique lines stays as in the original (unless you sort). Last occurrence keeps the bottommost copy of each repeated line and drops earlier duplicates, which matters when later lines were corrected or updated.
With trim on, leading and trailing spaces are ignored when comparing lines, so apple and apple count as the same line (the kept line keeps its original spacing). With
case-insensitive on, Apple and apple match; the kept line is unchanged from the source.
Optional sort reorders the deduplicated lines using the browser’s localeCompare (numeric-aware). This destroys original order — use it when you want a sorted unique list, not when sequence matters.
No. Deduplication runs in your browser. Drafts may be saved in localStorage on this device only.
Each line is turned into a comparison key: optionally trimmed and optionally lowercased. Lines with the same key are considered duplicates; one copy is kept according to your “first” or “last” setting.
Yes. Multiple blank lines usually collapse to one kept empty line, because empty keys match. If you need to preserve repeated blank lines, this tool is not the right fit.
uniq?
Similar goal, but uniq traditionally expects sorted input for a full unique pass. Here you can dedupe without sorting, or sort in the tool when you want alphabetical unique lines.
Keys are prefixed with droidxp-dlr-: input text, trim, case-insensitive, keep mode, and sort. Clear removes them.
Yes. Lines are compared as JavaScript strings. Case folding uses toLowerCase(), which follows Unicode rules for many scripts; verify edge cases for your language.
Lines are split on both \n and \r\n. Trailing \r is not usually visible but is part of the line unless you trim.
Only whole lines are compared. Multi-line records should be normalized elsewhere (e.g. one record per line) before using this tool.
Follow your policy. Nothing is sent to DroidXP, but screen capture, extensions, and backups can still expose clipboard or page content.
After the page is cached, it can work offline. No network is required for deduplication.
