Remove Duplicate Lines

Remove duplicates and sort lines.

Deduplicate lists in seconds while keeping the original order or sorting alphabetically.

The duplicate remover is ideal for cleaning contact lists, scripts, environment files, or any document where every line represents one record. Choose between preserving the original order or producing a clean alphabetical list. Before deduplication happens, the tool trims whitespace, normalizes line endings, and collapses empty rows to give you deterministic results.

It supports multilingual content and treats accented characters consistently, so Spanish names or Chinese identifiers are never lost. A small activity summary shows how many lines were removed, making it easy to document the cleanup. Because processing is local, sensitive IDs or unpublished copy never leave your browser.

Helpful callouts recommend the next step in your workflow. You can jump to the whitespace cleaner to normalize spacing before deduping or send the output straight into a word counter to create deck-ready stats.

How to use

Paste your raw text into the input column. Pick whether you want to keep the original order or sort alphabetically, then press “Deduplicate.” Results appear instantly on the right with a count of removed lines. If you paste new text, the previous state disappears automatically.

Click “Copy result” to place the cleaned block on your clipboard. The formatter preserves line breaks, so you can move it into spreadsheets, CMS fields, or automation scripts without extra work.

FAQ

Will the tool respect Windows and macOS line endings?

Yes. We convert CRLF, CR, and LF to a single format before deduping, so you receive a predictable output.

Can it handle comma-separated values?

Absolutely. Deduplication works at the line level and will not split commas or tabs that belong to the same record.
