Wrap Lines in Quotes
Quote or bracket every line and add a trailing separator — turn a column of values into a SQL IN list, JSON array, or CSV row. Runs in your browser; nothing is uploaded.
About this tool
Wrap Lines in Quotes puts your chosen quotes or brackets around every line
of text and, optionally, adds a trailing separator — so a pasted column of
values becomes a ready-to-use SQL IN (…) list, JSON array, or CSV row. It all
runs locally in your browser via WebAssembly; nothing is uploaded.
- Wrap style — pick double
"…", single'…', backticks`…`, parentheses(…), square[…], curly{…}, angle<…>, or guillemets«…». Choose Custom to type your own opening/closing delimiters (leave the closing one empty to mirror the opening one). - Trailing separator — appended after each wrapped line. Type
,to build a comma-separated list. By default the last line omits it, so the result is a validIN (…)/ array body; tick Separator after the last line too to keep it. - Skip blank lines — on by default: blank / whitespace-only lines pass through unchanged (not wrapped, no separator).
- Trim whitespace — strips leading/trailing spaces on each line before wrapping.
- Escape the delimiter inside lines — backslash-escapes the quote (and any
\) that already appears in a line, so a value like5" pipebecomes a valid"5\" pipe"instead of breaking your string.
Worked example
Paste three values, choose single quotes, and set the separator to ,:
apple
banana
cherry
You get a drop-in SQL IN list body:
'apple',
'banana',
'cherry'
Wrap the same lines in square brackets with no separator and each becomes
[apple], [banana], [cherry].
Handy for
- Building
WHERE col IN ('a','b','c')clauses from a spreadsheet column. - Turning a list into a JSON/Python array of strings.
- Quoting shell arguments or config values line by line.
FAQ
How do I make a SQL IN list or a JSON array?
Paste one value per line, pick your quote style (single quotes for SQL, double
for JSON), and set the Trailing separator to ,. Every line is quoted and
comma-separated, and the last line drops the trailing comma by default, so
you can paste the result straight inside IN ( … ) or [ … ] without a syntax
error. Wrap the whole block in parentheses or brackets yourself.
What happens to blank lines?
With Skip blank lines on (the default), any empty or whitespace-only line is
left exactly as it was — it isn't quoted and doesn't receive a separator, so the
surrounding lines still form a clean list. Turn the option off to wrap every
line, including blank ones (a blank line then becomes an empty pair like "" or
[]). The result also reports how many of the total lines were wrapped.
My values contain quotes — won't that break the output?
Enable Escape the delimiter inside lines. It backslash-escapes any
occurrence of the delimiter — and any literal backslash — inside each line
before wrapping, so 5" pipe becomes "5\" pipe" and a\b becomes "a\\b".
That keeps double-quoted JSON/SQL string literals valid. Without it, inner
quotes are left as-is (useful when you know they're already safe).
Can I use my own brackets or a multi-character wrapper?
Yes. Set Wrap style to Custom and type the opening delimiter (e.g.
<!--) and closing delimiter (e.g. -->). If you leave the closing field
empty, it mirrors the opening one, so typing | wraps each line as |value|.
Multi-character delimiters like << / >> work too.
Limits & notes
- Lines are split on newlines only; the tool never re-wraps or reflows long lines. A trailing newline in the input does not create an extra empty line.
- Escape covers only the delimiter characters and backslashes — it is not a full JSON/CSV encoder (it won't escape tabs or control characters).
- Everything is processed in-browser; large pastes are limited only by your device's memory.
