Add Prefix & Suffix to Lines

Quick answer: Add Prefix & Suffix to Lines is a free online tool to add prefix suffix to each line: wrap every line with your own prefix and suffix — quotes, bullets, HTML tags, anything. Free with no signup or download: get results instantly, all inside your browser.

Wrap every line with your own prefix and suffix — quotes, bullets, HTML tags, anything. Free, no signup.

What is the Add Prefix & Suffix to Lines?

Add prefix and suffix to lines wraps every line of your text with custom strings you define — a prefix added before each line and a suffix added after it. Turn a plain list into quoted CSV values (‘apple’, ‘banana’), bullet points, HTML list items, or code array elements in a single operation.

This free add prefix suffix to each line tool accepts any prefix and suffix: text, punctuation, quotes, HTML tags like <li>…</li>, or code syntax like double quotes and commas. The transformation is live — type your affixes and watch every line update instantly.

Developers formatting data for code, writers building HTML lists from plain text, and analysts quoting values for SQL or spreadsheets use it constantly. Everything runs locally in your browser — no signup, no uploads, no limits.

A few combinations cover most real jobs. Single quotes around each line plus nothing else prepares values for SQL IN clauses; double quotes with a trailing comma build JavaScript or Python array literals; li tags produce HTML list items ready to drop into a page; a ‘- ‘ prefix makes markdown bullets. Because the transformation is live, you can experiment freely — type an affix, see every line update, adjust until the output pastes perfectly into its destination.

How to use the Add Prefix & Suffix to Lines

  1. Paste your multi-line list into the input box.
  2. Type your prefix (added before each line) and suffix (added after each line).
  3. Watch the output update live as you type the affixes.
  4. Try combinations: quotes for CSV, <li> tags for HTML, or ‘- ‘ for markdown bullets.
  5. Copy the wrapped lines or download them as a .txt file.

Add Prefix & Suffix to Lines use cases

Building quoted CSV values

A column of names becomes ‘Alice’, ‘Bob’, ‘Charlie’ — paste-ready for SQL IN clauses, spreadsheet formulas, and config files. The result pastes directly into SQL clauses and spreadsheet formulas. It beats manual wrapping by a mile.

Generating HTML lists

Prefix ‘<li>’ and suffix ‘</li>’ turn a plain list into HTML list items instantly, ready to drop between <ul> tags. Drop the wrapped items straight between your ul tags. Both fields are optional, so one-sided wrapping works.

Formatting code arrays

Wrapping lines in quotes with trailing commas converts a pasted list into a valid JavaScript, Python, or JSON array skeleton. Pasted lists become valid array skeletons in seconds. The output updates live as you type.

Creating markdown bullets

A ‘- ‘ prefix turns any plain list into proper markdown bullets for READMEs, docs, and notes. READMEs, docs, and notes get properly formatted markdown bullets instantly. It beats manual wrapping by a mile.

Quoting values for SQL queries

A column of IDs pasted from a spreadsheet becomes ‘101’, ‘102’, ‘103’ with quote affixes — ready to drop into a SQL IN clause or a spreadsheet TEXTJOIN formula without manual quoting. It beats quoting hundreds of values by hand.

Tips

  • Leave prefix or suffix empty to add only one side — both fields are optional.
  • HTML in affixes is inserted as literal text, so ‘<li>’ appears as characters you can paste into code.
  • Empty lines get the affixes too; remove blank lines first if you want them skipped.
  • For numbering instead of fixed text, use the Add Line Numbers tool.
  • Combine with Add Line Numbers first when you need numbered, wrapped items.

Frequently asked questions

Is this prefix suffix tool free?
Yes. Free with no signup and no limits — wrap as many lines as you want, in your browser. Wrap as many lines as you want — no signup, no quotas, and no premium tier at all. The output updates live as you type.
What can I use as a prefix or suffix?
Anything: plain text, punctuation, quotes, HTML tags, markdown symbols, or code syntax. Both fields accept any characters you type. Anything you type is inserted literally — plain text, punctuation, HTML tags, markdown symbols, or code syntax. It beats manual wrapping by a mile.
Do I have to fill in both fields?
No. Leave either blank to add only a prefix or only a suffix — for example, just a '- ' prefix for markdown bullets. Leave either field blank: single-sided wrapping covers most real-world needs perfectly well. Both fields are optional, so one-sided wrapping works.
Are empty lines affected?
Yes, empty lines receive the prefix and suffix like any other line. Remove blank lines beforehand with the Whitespace Remover if you want them skipped. The output updates live as you type. It beats manual wrapping by a mile. Both fields are optional, so one-sided wrapping works.
Can I add line numbers instead?
For sequential numbering use the Add Line Numbers tool; this tool adds the same fixed text to every line rather than counting. Use the Add Line Numbers tool — it counts sequentially instead of repeating fixed text. The output updates live as you type.
Is my list data transmitted anywhere?
No. The prefix and suffix wrapping is computed locally in your browser. Your lists, code fragments, and data values never cross the network. Everything happens on your device, instantly and privately. No signup is needed and nothing is recorded. Private by design.
Can the prefix contain line breaks?
No — the prefix and suffix are single-line strings applied to each line as-is. For multi-line wrappers around the whole block, apply the tool first, then add your opening and closing lines manually. One line in, one line out, every time.
How do I make a JSON array from a list?
Set the prefix to a double quote and the suffix to a double quote plus comma, then wrap the result in square brackets yourself. Each line becomes a quoted element ready for code. Remove the trailing comma on the last element.
Can I add different text to each line?
No — the same prefix and suffix apply to every line uniformly. For per-line variation, number the lines first with Add Line Numbers, or edit the few exceptions manually afterwards. Uniform wrapping is the tool's entire job. Uniformity is the point.
