Add Prefix & Suffix: 8 Practical Use Cases

Wrapping every line with a prefix and suffix turns a plain list into structured text in seconds — it is how people build HTML lists, SQL value rows, CSV columns, JavaScript arrays and command-line loops without editing each line by hand. The examples below show exact before-and-after results, so you can match your task to the right pair of affixes.

Real-world examples

Consider a common developer chore. You have a column of IDs copied from a spreadsheet and need them as a SQL IN clause. Paste the IDs, set the prefix to a single quote and the suffix to ',, and the plain list becomes quoted, comma-separated values ready to drop between parentheses — a task that would be tedious to do line by line for a few hundred rows.

Goal	Prefix	Suffix	Result per line
HTML list items	<li>	</li>	<li>item</li>
JS array strings	"	",	"item",
Markdown bullets	-	(none)	- item
SQL values	('	'),	('item'),
CLI commands	rm	(none)	rm item
Full URLs	https://site.com/	(none)	https://site.com/item

Worked workflow: build an HTML dropdown

1. Paste your option labels, one per line.
2. Set the prefix to <option> and the suffix to </option>.
3. Copy the output straight into your <select> element.

A twenty-item menu that would take minutes of repetitive typing is done in one paste.

Worked workflow: turn a keyword list into hashtags

Marketers often keep plain keyword lists. To convert them into social hashtags, set the prefix to # and leave the suffix empty. Every keyword becomes a hashtag instantly, ready to paste into a post or content calendar. Enable "Skip blank lines" so any spacing between keyword groups survives the transformation.

Worked workflow: prepare CSV rows for import

When you have values that need a trailing delimiter for a CSV or a config file, set the suffix to a comma. If each value also needs quoting, add the opening quote as a prefix and a closing quote plus comma as the suffix. The list becomes import-ready rows without opening a spreadsheet — and because it all runs locally, even a list of private customer references never leaves your machine.

• Developers building arrays, SQL, HTML and shell commands from raw data.
• Data wranglers reshaping exported columns into new formats.
• Marketers converting keyword lists into hashtags or tracked URLs.
• Writers and editors turning plain lists into Markdown or formatted text.

FAQ

How do I turn a list of IDs into a SQL IN clause?

Use a single quote as the prefix and ', as the suffix to produce quoted, comma-separated values, then wrap the whole block in parentheses. Remove the trailing comma on the last line.

Can I make hashtags from a keyword list?

Yes. Set the prefix to # and leave the suffix empty, and every keyword becomes a hashtag on its own line, ready to paste into a post.

What's the fastest way to build an HTML list?

Paste your items, set the prefix to the opening tag and the suffix to the closing tag, and copy the result directly into your page — no manual tagging required.

Is it safe to reformat private data this way?

Yes. Everything is processed in your browser and nothing is uploaded, so lists containing internal IDs, emails or references stay on your device.
