List Tools is a free workspace for YouTube tags, keywords, and other plain-text lists. Convert between comma-separated and line-based formats, sort or randomize items, and add a prefix or suffix to every line—then copy the result back into Studio or your sheet.
Use Convert when paste arrives as a comma list or needs line breaks; Randomize when you want a shuffled batch; Prefix/Suffix when every tag needs the same wrapper. Everything runs in your browser with no account or signup.
How to use List Tools
Pick a tab below, paste your list, run the action, then copy the output. Switch tabs anytime—Convert, Randomize, and Prefix/Suffix each keep their own panel.

List Tools FAQ
What can List Tools do?
Convert between commas and lines, randomize or reshuffle items, and add the same prefix or suffix to every line—handy for YouTube tags, keyword batches, and upload-ready lists.
Do I need an account?
No. List Tools is free in the browser with no signup or paywall.
Is my list uploaded to a server?
Transforms run in your browser on this page. Nothing is stored on our servers unless you copy the result elsewhere yourself.
When should I use Text Cleaner or Text Counters instead?
Use Text Cleaner when the paste is messy (spaces, HTML, case). Use Text Counters when you only need character or word length. Use List Tools when the job is formatting, shuffling, or wrapping list items.
