Text Prefix / Suffix Adder
Add a custom prefix, suffix, or both to every line of text at once — great for bulk formatting, code generation, and data prep.
About Text Prefix / Suffix Adder
The Text Prefix / Suffix Adder takes a block of text and adds a specified prefix string, suffix string, or both to the beginning and end of every line simultaneously. This is a highly practical text processing utility for developers and data workers who need to wrap each item in a list with quotes, add SQL commas, prepend indentation, add Markdown list markers, wrap lines in HTML tags, or perform any similar per-line transformation in bulk. Skip-blank-lines mode lets you apply changes only to non-empty lines, avoiding unwanted markers on empty lines between paragraphs.
Why use Text Prefix / Suffix Adder
- Processes every line in a large block of text simultaneously.
- Skip-blank-lines option keeps paragraph spacing clean.
- Supports any prefix/suffix — quotes, brackets, tags, commas, and more.
- Instant live preview as you type the prefix or suffix.
- Eliminates manual editing for line-by-line bulk transformations.
- Works with any printable character — no escaping or quoting needed.
How to use Text Prefix / Suffix Adder
- Paste your text (one item per line) into the input area.
- Enter the desired prefix in the Prefix field and/or a suffix in the Suffix field.
- Toggle 'Skip blank lines' if you want empty lines left unchanged.
- Copy the processed output from the result area.
- Use the live preview to verify the prefix/suffix appears exactly where you expect.
- Toggle 'Skip blank lines' if you have paragraph-style input where empty lines should remain empty.
- For complex transformations, run a second pass — e.g. first add quotes, then add commas as suffix.
When to use Text Prefix / Suffix Adder
- Wrapping each item in a list with SQL single quotes for a query.
- Adding a leading hyphen to every line to create a Markdown list.
- Prefixing each line with a tab for code indentation.
- Adding <li> and </li> HTML tags around each item in a list.
- Generating SQL INSERT VALUES from a list of names by adding ('quotes,').
- Preparing CSV cells from a column of values with prefix and suffix wrapping.
Examples
SQL list
Input: Alice
Bob
Carol
Output: ('Alice'),
('Bob'),
('Carol'),
Markdown bullets
Input: Apples
Oranges
Bananas
Output: - Apples
- Oranges
- Bananas
HTML list items
Input: First
Second
Third
Output: <li>First</li>
<li>Second</li>
<li>Third</li>
Tips
- For SQL INSERTs, prefix with "('" and suffix with "')," to wrap each value in single quotes followed by a comma.
- For HTML lists, prefix with '<li>' and suffix with '</li>' to create proper list items.
- For Markdown bullet lists, prefix with '- ' (hyphen space) — no suffix needed.
- When generating shell commands, prefix with the command name (e.g. 'rm ') so each line becomes a self-contained command.
- Combine with Find & Replace for more complex transformations that depend on per-line content.
Frequently Asked Questions
Does it add the prefix/suffix to blank lines too?▾
By default yes, but you can toggle 'Skip blank lines' to leave empty lines untouched.
Can I use special characters like quotes or backslashes in the prefix/suffix?▾
Yes. Any printable character can be used as part of the prefix or suffix string.
Is there a line count limit?▾
No. The tool handles any number of lines — processing is instantaneous even for thousands of lines.
Can I add a newline inside the prefix or suffix?▾
The prefix and suffix fields are single-line inputs, so embedded newlines are not supported. Each line gets the literal text you enter.
How is 'line' defined?▾
Lines are delimited by newline characters (\n). Windows-style \r\n line endings are normalized automatically.
Can I use a tab character as the prefix?▾
Tab keys typically don't enter into single-line inputs. As a workaround, paste a tab character from elsewhere or use a fixed number of spaces.
Will it handle very long lists?▾
Yes. Thousands of lines are processed instantly because the operation runs locally in your browser.
Does it strip trailing whitespace from lines?▾
No — the tool only adds prefix/suffix. To trim whitespace first, use the Whitespace Cleaner tool, then this one.
