Line Sorter & Duplicate Remover

Paste a list (one item per line) and clean it up in one go — sort alphabetically, remove duplicates, trim spaces, and drop blank lines. Useful for keyword lists, email lists, tags, CSV columns and any messy pasted text. Runs in your browser; nothing is uploaded.

FAQ

How do I remove duplicate lines from a list?

Paste your list, tick "remove duplicates", and the tool keeps only the first occurrence of each line. Combine it with sorting and trimming to clean a messy list in one step.

How do I sort a list alphabetically?

Paste your lines and choose A–Z (or Z–A). You can sort and dedupe at the same time, and optionally ignore case so "Apple" and "apple" are treated as equal.

Is my data private?

Yes. Everything runs in your browser — your text is never uploaded, logged or stored. It works offline once the page has loaded.

What can I use this for?

Cleaning email or keyword lists, deduping CSV columns, tidying import files, alphabetizing names or tags, and removing blank lines from pasted text. Anything that comes as one item per line.
