Add Prefix / Suffix to Lines
Add a prefix and/or suffix to every line of text. Wrap lines with custom text. Free online tool with live preview.
Why Use the Add Prefix/Suffix Tool?
Adding consistent prefixes and suffixes to lines is a common task when formatting lists for HTML, Markdown, programming, or data import. Our tool makes it easy to wrap every line with custom text, with a live preview of the first line result.
Key Features
- Separate prefix and suffix inputs for maximum flexibility
- Live preview showing the effect on the first line
- Common use-case placeholders (bullet points, HTML tags, commas)
- Side-by-side input and output for easy comparison
How to Use
- Enter the prefix text (added before each line) and/or suffix text (added after)
- Paste your text in the input area
- Copy the wrapped result from the output area
Technical Details
Each line is processed independently by concatenating the prefix, original line content, and suffix. Empty lines are also processed (receiving just prefix + suffix). This ensures consistent formatting even with blank lines. The live preview updates in real-time as you type.
FAQ
Can I use both prefix and suffix at the same time?
Yes! You can use either, both, or neither. Leave any field empty to skip adding that part.
What are common use cases?
Popular uses include: wrapping lines in HTML tags (<li>...</li>), adding bullet points (• ), appending commas or semicolons, and wrapping strings in quotes.
