Line Prefix / Suffix Adder

Summary

The Line Prefix / Suffix Adder lets you wrap every line of a block of text with custom strings in one step. Paste your content, enter a prefix, a suffix, or both, and the output updates live. Use it to quote lines, wrap values in SQL or code, add bullet markers, or prepend timestamps — all without writing a script.

How it works

1. Paste or type your text into the Input box.
2. Enter the string you want added before each line in the Prefix field.
3. Enter the string you want added after each line in the Suffix field.
4. The Output box updates live as you type.
5. Click Copy Output to copy the result to your clipboard.
6. Click Clear to reset all fields and start over.

Use cases

• Wrap CSV values in SQL INSERT parentheses.
• Add a bullet marker or list number prefix to every line.
• Quote every line with > for Markdown block quotes.
• Prepend a timestamp or log tag to each line.
• Surround each line with HTML tags (e.g. <li> ... </li>).
• Add a common file path prefix to a list of filenames.
• Wrap each line in quotes for use in a JSON or YAML array.
• Append a constant suffix such as .com to a list of domain names.
