How to use Add an Underscore to List Items
- 1. Paste your list. Put one item per line into the input pane, such as words you want to visually underline without HTML formatting.
- 2. Check the combining character insertion. The tool inserts a combining low line character after every letter, so 'apple' renders as 'a̲p̲p̲l̲e̲' with an underline effect that survives plain text.
- 3. Copy the underlined list. Copy the result and paste it into a bio, chat message, or plain-text field where an underline would otherwise require HTML or rich text.
When to use Add an Underscore to List Items
Add an Underscore to List Items inserts Unicode combining low line marks after each character, producing an underline effect in plain text. Use it whenever you want emphasis that looks like an underline but the platform you are posting to strips any real formatting.
- Underlining a heading in a plain-text signature. An email or forum signature only supports plain text, but you want a section heading to look underlined. Convert the heading list and paste it into the signature field.
- Marking important items in a shared list. You are sharing a checklist in a messaging app and want certain critical items visually marked. Underline just those items so they stand out from the rest.
- Styling a username with an underline effect. A platform's display name field is plain text only, but you want part of it underlined for style. Convert a short word list and use the result as your name.
- Formatting quiz answers with underlines. You are typing a fill-in-the-blank quiz in a plain-text document and want the correct answers underlined for the answer key. Convert the answer list before pasting it in.

About the Add an Underscore to List Items tool
Add an Underscore to List Items runs as plain JavaScript in your browser tab, with no server behind it. Add underscores to items. 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.
There is nothing to configure. Provide the input and the result appears on its own. 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 an Underscore to 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.
