How to use Add a List Item Suffix
- 1. Paste your list. Enter your items into the input pane, one per line. Any list where every entry needs the same text appended at the end works here.
- 2. Enter a suffix. Type the text to place after every item in Suffix, such as a comma, a file extension, or a closing punctuation mark shared by every entry.
- 3. Decide whether to skip empty items. Turn on Skip empty list items so blank lines stay blank instead of getting the suffix appended to them as well.
- 4. Copy the updated list. The output pane shows every item with the suffix added to the end. Copy the updated list into your document, code or spreadsheet.
When to use Add a List Item Suffix
Add a List Item Suffix appends the same text to the end of every item in a list. Reach for Add a List Item Suffix whenever a list needs a consistent trailing marker, extension or punctuation on every line.
- Adding a file extension to a list of names. A list of bare filenames all need the same extension, such as '.jpg', appended so they become complete filenames ready to reference in code.
- Turning a list into comma-separated statement fragments. A list of values needs a trailing comma added to every line except potentially the last, so it reads as a comma-separated block when pasted into code.
- Appending a shared domain to a list of usernames. A list of usernames needs to become full email addresses sharing the same domain, which appending that domain as a suffix produces in one step.
- Closing off a list of quoted phrases. A list of phrases needs a closing punctuation mark added consistently, such as a period, so every line reads as a complete sentence.

About the Add a List Item Suffix tool
Add a List Item Suffix runs as plain JavaScript in your browser tab, with no server behind it. Append a suffix after each list item. Whatever you put in stays on your device from start to finish.
The tool is part of EditSafely's List Tools section, 114 single-purpose utilities built around the same idea: open the page, get the result, keep your data to yourself.
You can shape the output with 2 settings, including Suffix and Skip empty list 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.
That local-first design has practical benefits beyond privacy. The tool keeps working on a flaky connection once the page has loaded, results are instant because nothing round-trips to a server, and it is safe to use with confidential material.
Frequently asked questions
Is Add a List Item Suffix 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.
