Line Sorter / Deduper

Sort lines A-Z or Z-A and remove duplicate lines. Runs entirely in your browser. Nothing is sent to Formsig.

About this tool

Paste a list, sort ascending or descending, and optionally remove duplicate lines. Handy for tag lists, email lists, sitemap paths, and form option values.

Features

  • A-Z and Z-A sort
  • Case-sensitive or insensitive compare
  • Remove duplicate lines (keep first)
  • Trim lines before compare as an option

Common use cases

  • Cleaning option lists for select fields
  • Deduping pasted email or domain lists
  • Sorting paths or slugs alphabetically
  • Preparing unique keywords for a brief

How it works

Text is split on newlines. Optional trim runs first. Sort uses localeCompare. Deduping keeps the first occurrence of each line key.

Privacy: this utility runs in your browser. Formsig serves the page but does not need your input to compute results.

FAQ

Are blank lines removed?

Blank lines are kept unless you enable trim-and-drop-empty. Deduping treats identical blanks as duplicates when enabled.

Is data uploaded?

No. Sorting runs locally.
