Add Prefix and Suffix to Lines

Add Prefix and Suffix to Lines takes a plain list and puts the same text at the start or end of every line. It sounds small, and it is exactly the kind of small job that takes twenty minutes by hand and two seconds here when a list runs to hundreds of rows.

The usual reasons are mechanical. Wrapping each line in quotes and adding a comma turns a list of names into an array or a SQL IN clause. Adding a domain in front of each path turns a list of slugs into full URLs. Adding a bullet character or a dash turns a plain list into a Markdown list.

Line numbering is built in, with a choice of starting number, padding and separator, so you can produce 01. through to 99. without counting. An option skips blank lines so numbering stays continuous, and another trims each line before wrapping it, which matters when the list was pasted from a spreadsheet.

• Prefix, suffix or both on every line
• Optional sequential numbering with a chosen start
• Zero padding so numbers line up
• Skip or keep blank lines
• Trim each line before wrapping it
• Shows how many lines were changed
• Copy and download the result

The add prefix and suffix to lines is used by writers, developers, students, marketers and anyone else who needs the job done once without installing software. Common cases include:

• Turning a list of values into a SQL IN clause or a code array
• Adding a domain in front of a list of paths
• Converting a plain list into Markdown bullets or a numbered list
• Adding quotes and commas around every item for a CSV row
• Numbering a list of steps or questions
