Tool Introduction

Tool Overview

Every developer and writer keeps a hidden tab open for sorting a list, deleting duplicates, or numbering rows. This tool collects the common one-liners into a single page so you don't have to hop between sites. All operations run client-side and preserve your original text — change the operation and the output regenerates instantly.

Use Cases

Sort a list of imports, dependencies, or env keys alphabetically
Remove duplicate emails from a contact list before importing
Number a checklist for a meeting
Reverse a stack-trace top-to-bottom for readability
Shuffle a list of names for random draws
Wrap each line of a list in quotes for code or SQL pasting

Input/Output Examples

Operation: dedupe (case-insensitive), then sort ascending — apple, banana, cherry remain.

Input Intent

FAQ

Is the sort stable?+

Yes. Modern browser sort implementations are stable, so equal items keep their relative order.

What's the difference between 'reverse order' and 'reverse text'?+

Reverse order flips the list bottom-to-top while keeping each line intact. Reverse text flips the characters inside every line.

Does shuffle use cryptographically secure randomness?+

It uses Math.random with Fisher-Yates — fine for non-security shuffles like sampling. For raffles or security-sensitive picks, use a dedicated secure random tool.

Are case-insensitive comparisons locale-aware?+

Yes. Sorting uses Intl.Collator-style localeCompare, so accented characters and non-Latin scripts collate correctly for your locale.
