How to use Join List Items
- 1. Paste your list. Enter your items into the input pane, one per line. Any list you need collapsed onto a single line works here.
- 2. Enter a separator. Type the string to place between items in Separator, using \n for newline or \t for tab if it is not a printable character, such as a dash, comma or space.
- 3. Decide whether to skip empty items. Turn on Skip empty items to leave blank lines out of the joined result entirely, so you don't end up with two separators in a row where a blank line was.
- 4. Copy the joined result. The output pane shows all items combined into one line with your chosen separator between them. Copy it into a sentence, filename or code snippet.
When to use Join List Items
Join List Items combines every item in a list into a single line, separated by a string you choose. Reach for Join List Items whenever a multi-line list needs to become one compact value.
- Building a comma-separated tag string. A list of tags on separate lines needs to become a single 'tag1, tag2, tag3' string to store in a database field or paste into a form.
- Creating a slug from words. A list of words like 'my', 'blog', 'post' needs to become a single hyphenated slug such as 'my-blog-post' for a URL, which joining with a dash produces directly.
- Turning a list into a readable sentence fragment. A list of names needs to appear as 'Alice, Bob, Carol' in a sentence rather than as separate lines, which a comma-and-space separator produces in one step.
- Skipping blank lines while joining. A pasted list has some empty lines mixed in from formatting, and turning on skip empty items keeps the joined string from having doubled or trailing separators.

About the Join List Items tool
Join List Items is a free online tool that works entirely inside your web browser. Join all items of a list together. Because the processing happens on your own device, nothing you enter is uploaded, logged or stored anywhere.
This page is one of 114 List utilities on EditSafely. Each one does a single job well, and all of them follow the same rule: your input stays on your machine.
You can shape the output with 2 settings, including Separator (\n for newline, \t for tab) and Skip empty items, and the result refreshes the moment you change one. A worked example further down the page shows exactly what the tool produces for a real input.
Because nothing leaves your device, the tool is suitable for sensitive content such as internal documents, credentials or customer data. It also responds instantly, since every keystroke is handled on your own machine rather than by a remote API.
Frequently asked questions
Is Join List Items free to use?
Yes, it is completely free. All 2,658 tools on EditSafely work without an account, a subscription or usage limits.
Is it safe to paste sensitive or confidential data?
Everything happens locally. Your browser downloads the tool's code once, then does all the processing itself; nothing you enter is transmitted, stored or logged. You can even go offline after the page loads and it will still work.
How much text can I process at once?
There is no fixed limit. Because the work happens on your own device rather than on a shared server, the practical ceiling is your machine's memory, which comfortably handles inputs far larger than typical online tools allow.
Do I need to sign up or install anything?
No. The tool works in any modern browser on desktop, tablet or phone. There is no account to create, no extension to add and no software to install.
How do I use the result?
The output panel has a one-click copy button, and you can keep refining the input while you work; the result updates in place as you type.
