Add Text Prefix Online

What is an Online Text Prefix Adder Tool?

An online text prefix adder is a simple but powerful tool that lets you add custom text (a "prefix") to your content in bulk—no more typing the same thing at the start of every line, paragraph, or section manually. Whether you’re formatting a list with bullet points, adding numbering to instructions, labeling data entries, or adding custom tags to text, this tool saves you hours of repetitive work.

Unlike basic text editors that force you to edit line by line, this tool gives you full control over where and how the prefix is added. You can add a prefix to every line of text, the very start of your entire document, each paragraph, or even after a specific character (delimiter) like a comma or semicolon. Plus, it includes handy options like adding a space after the prefix (so your text doesn’t run together), skipping empty lines, and choosing whether to place the prefix before or after your target text.

Best of all, it works entirely in your browser—no software to install, no account needed, and your text never leaves your device. It’s perfect for anyone who works with lists, data, or bulk text: content creators, office workers, programmers, students, and more.

• Add custom prefixes to every line (ideal for formatting lists, logs, or data entries)
• Add a prefix to the start of the entire text (great for adding titles or labels)
• Add prefixes to each paragraph (perfect for formatting essays, articles, or reports)
• Add prefixes after a custom delimiter (useful for labeling specific parts of text)
• Optional space after prefix to keep text readable
• Skip empty lines/paragraphs to avoid unnecessary prefixes
• Choose prefix position (before or after target text)
• Case-sensitive delimiter option for precise control

How to Use the Online Text Prefix Adder (Step-by-Step)

1. Paste your text into the input box. You can type directly, copy from a Word document, Excel spreadsheet, Notepad, website, or any other source—there’s no limit to the amount of text you can process (though very long texts may take a few extra seconds).
2. Enter your custom prefix in the "Prefix to Add" box. This can be anything: a bullet point (*), number (1.), symbol (-), label (Note:), emoji (✅), or even a longer phrase (Important: ). Be as creative as you need—there’s no character limit for the prefix.
3. Choose where to add the prefix from the "Add Prefix To" dropdown:
   • Each Line: Adds the prefix to the start of every line (most common use case—great for making lists from plain text).
   • Start of Entire Text: Adds the prefix only once, at the very beginning of your text (perfect for adding a title or header).
   • Each Paragraph: Adds the prefix to the start of every paragraph (a paragraph is defined as text separated by two line breaks).
   • After Custom Delimiter: Adds the prefix right after a specific character or string (e.g., add "Item: " after every semicolon in your text). When you select this, a "Custom Delimiter" box will appear—enter the character/string you want to use (e.g., ; , | :).
4. Adjust basic options:
   • Add Space After Prefix: Check this box (default is checked) to add a single space between the prefix and your text (e.g., "* Apple" instead of "*Apple"). This keeps your text clean and readable.
   • Skip Empty Lines/Paragraphs: Check this to avoid adding prefixes to blank lines or empty paragraphs (useful if your text has extra line breaks).
   • Case Sensitive Delimiter (only for custom delimiter): Check this if you want the delimiter to match exact case (e.g., "A" is different from "a").
5. Use advanced options (optional):
   • Prefix Position: Choose "Before Target" (default) to add the prefix before your text, or "After Target" to add it after (e.g., add " - Done" after each line instead of before).
6. Click "Add Prefix" to process your text. The result with your custom prefix will appear in the output box instantly.
7. Use the result tools: Copy the result to your clipboard with "Copy Result", download it as a .txt file with "Download .txt", or load an example to test how the tool works.

Pro tip: The preview box shows exactly what your text will look like with the prefix added, so you can adjust your settings before finalizing—no need to guess if it will look right!
