Trim · dedupe · sort

A clean list, with every change accounted for.

ListClean processes up to 20,000 one-item-per-line entries entirely in your browser and keeps removals visible.

No account, upload, backend, saved list, file reader or result URL.

Three explicit steps

Paste, choose, reconcile

01

Paste one item per line

Physical line breaks define item boundaries; no CSV guessing occurs.

02

Select exact transformations

The fixed pipeline keeps trimming, blanks, duplicates and ordering predictable.

03

Review output and counts

Input, output and removal counts expose what changed before you copy.

Neutral text organization

Useful for ordinary lists copied between tools

  • Deduplicate tags, labels or non-sensitive names before import.
  • Sort filenames and numbered labels in natural order.
  • Remove empty rows from text copied out of a document.
  • Trim accidental edge spaces without changing internal formatting.

Reproducible inputs

Verify mixed cleanup and stable deduplication

Both examples match presets and reconcile every input, removal and output count.
