Add Prefix & Suffix to Each Line
Add text to the start and end of every line at once: bullets, quotes, HTML tags, commas or line numbers. Free, fast and private.

Editing a long list line by line is slow and error-prone. This tool adds a prefix to the beginning and a suffix to the end of every line at once. Typical jobs include turning a list of words into Markdown bullets, wrapping values in quotes and adding a trailing comma for code, putting each line inside <li> tags, prefixing log lines with a label, adding a file extension to a list of names, or commenting out a block of code with // or #.
Presets fill in the most common combinations with one click, and you can type anything you like in the two boxes, including spaces, punctuation, HTML and emoji. The result updates as you type, so it is easy to experiment. Empty lines are skipped by default so blank separators stay blank; untick the option if you want them wrapped too. "Trim lines first" removes indentation and trailing spaces before the prefix and suffix are added, which keeps the output tidy when the source came from a PDF or a web page.
Line numbers and reverse mode
Write {n} in the prefix or suffix to insert a running line number. "{n}. " creates a numbered list, "Step {n}: " labels instructions, and "id_{n}" generates simple identifiers. Numbering skips empty lines when they are being skipped, so the sequence stays continuous.
Need to undo a change? Tick "Remove instead of add" and the same prefix and suffix are stripped from every line where they appear. Lines that do not start or end with that exact text are left untouched, which makes it safe to clean up partially formatted lists — for example removing "- " bullets or trailing semicolons.
