Add prefix and suffix to each line

Puts text at the start and end of every line — quotes, bullets, tags, commas.

Type what you want before each line, what you want after it, or both, then press the button. Every line gets the same treatment; the order and the content of the lines are untouched.

Presets people reach for most

You can type anything into the two fields, but these are the combinations that come up again and again. Copy them straight in.

• SQL IN list — prefix ', suffix ',. Turns a column of IDs into 'a123', on every line, ready to paste between brackets.
• JSON or Python list — prefix ", suffix ",. The "Wrap in quotes + commas" button does this in one press and escapes any quotes already inside your lines.
• Markdown bullets — prefix - , suffix empty.
• Markdown checkboxes — prefix - [ ] .
• HTML list items — prefix <li>, suffix </li>.
• Quoting an email reply — prefix > .
• Building URLs — prefix https://example.com/, suffix /.
• CSS classes — prefix ., suffix { }.
• Hashtags — prefix #.
• Shell commands — prefix rm -f , turning a list of filenames into a script you can read before you run it.

Empty lines

By default empty lines are skipped, because adding <li></li> to a blank line produces an empty list item that then shows up in your page. Untick the option if you genuinely want every line touched, including blank ones — occasionally useful when the prefix is a comment marker and you want the blank lines commented too.

Order of operations

If your list came out of a spreadsheet or a PDF, run trim spaces before adding a prefix. Otherwise an invisible leading space ends up between your prefix and the text, which is exactly the kind of bug that survives review and breaks a query at 2am. The trim button on this page does it without leaving.

If you are going to join the lines into one comma-separated string afterwards, you usually do not need a suffix at all — the list converter adds the separators for you and does not leave a trailing comma on the last item, which the prefix/suffix approach does.

Doing it without this tool

Excel: ="prefix"&A1&"suffix" in a helper column, filled down, then copy and paste-special as values. Fine for a spreadsheet you are already in, awkward for text you are not.

Notepad++ or VS Code: Find & Replace with regular expressions on: search ^ and replace with your prefix, then search $ and replace with your suffix. Both editors also support column selection (Alt+drag), which lets you type a prefix into many lines at once — quick when the lines are visible on one screen, painful when there are four thousand of them.

Command line: sed 's/^/prefix/; s/$/suffix/' file.txt.

Word: use Find & Replace with "Use wildcards", searching for (*)^13. Most people give up and do it by hand, which is how the same typo ends up on line 40 and line 41.

How to use it

1. Paste your list into the box.
2. Type the text you want before each line into the Prefix field, and the text you want after it into Suffix.
3. Press "Apply to each line".
4. For a quoted, comma-separated list use "Wrap in quotes + commas" instead — it escapes quotes for you.
