Line Sorter — Sort Text Lines A–Z or Z–A

Quick paste from terminal history or Slack code block into sorter beats creating a CSV, importing Excel, sorting column, exporting. Developers live in text editors — line sort matches that muscle memory.

Firewall and nginx allowlist reviews expect alphabetical order for human scan — unsorted paste from ticket attachments sorts in one click.

Ascending A–Z is default for directories, glossaries, and enum documentation. Descending Z–A helps when newest lexical labels happen to sort last alphabetically — rare but useful for reverse display samples.

Sort stability preserves relative order of equal keys in many engines — duplicate lines adjacent before unique filter.

Toggle unique during sort to collapse duplicate entries — faster than sort then separate dedupe when building distinct IP or email lists.

When duplicate count matters, use duplicate-line-remover with keep-first policy instead to count removals explicitly.

String sort places 10 before 2 — zero-pad numeric lines or use numeric-aware tools for version numbers. IP addresses sort lexicographically not numerically — 192.168.1.10 before 192.168.1.2 — use ip-specific tools for CIDR lists when numeric order matters.

For dotted quads, specialized IP sorters beat plain lex sort — this page suits hostnames and mixed text lines.

Diff algorithms compare clearer when both sides sorted — sort allowlist exports from two environments before text-diff-checker to see set membership differences not order noise.

Order-insensitive equality checks: sort both sides identically then diff — only true additions and removals remain.

Customer email extracts and internal hostname inventories sort locally — no server logging of list contents.

Clear paste after processing PII on shared machines.

Line sorter optionally dedupes while ordering. duplicate-line-remover focuses on dedupe with keep-first or keep-last without mandatory sort — choose based on whether ordered output is required.

Chain sort then dedupe or use combined toggle when building clean unique sorted rosters.

Extract unique error messages from log tail paste — sort unique to prioritize frequent failures alphabetically for ticket titles.

Alphabetize dependency list before commit when team style guide requires sorted package.json adjacent files.

Mixed-case lines sort with uppercase before lowercase in ASCII order — normalize case with case-converter lowercase output before sort when case-insensitive roster needed.

DNS hostnames are case-insensitive but conventionally lowercase — lowercase before sort for presentation consistency.

Browser sort handles thousands of lines interactively. Hundreds of thousands may freeze tab — use sort CLI for bulk. Split files by section for interactive cleanup.

Remove empty lines manually or via duplicate-line-remover when blank rows pollute sorted output.
