How is this different from Word Quoter?

Word Quoter wraps every individual word, splitting on whitespace within a line. Line Quoter instead wraps each entire line as one unit, splitting only on newline characters, so multi-word lines stay together inside one pair of quotes.

What happens to empty lines?

An empty line still gets the quote character on both sides, producing a line containing just two quote characters back to back, like an empty quoted string.

Does it escape quote characters already inside the text?

No. The quote character is placed around each line verbatim, so a line already containing that character produces a literal that will not parse. Escape those occurrences beforehand, or choose a quote character the text does not use.

Line Quoter - Wrap Every Line in Quotes Online

Overview

Introduction

Turning a plain list of lines into a quoted array of string literals for code usually means manually adding quotes to the start and end of every line.

This tool automates that, and runs entirely client-side, so nothing you paste is ever uploaded to a server.

What Is Line Quoter?

A per-line quoting tool that wraps every individual line of your text with a chosen quote character, keeping each line as one quoted unit.

It's part of this site's String Tools collection and works entirely in your browser.

How Line Quoter Works

The tool splits the input on newline characters, wraps each resulting line with your chosen quote character on both sides, and rejoins the lines with newlines.

The transformation happens synchronously in JavaScript the moment you type, with no network round trip involved.

When To Use Line Quoter

Use it when you need to turn a plain list of values, one per line, into quoted string literals for code, like a list to paste into an array.

It's also useful for preparing line-delimited data for formats that expect quoted values.

Often used alongside Line Unquoter and String Quoter.

Features

Advantages

Keeps each full line intact as a single quoted unit, unlike per-word quoting.
Works with any custom quote character, not just double quotes.
Treats each line as a single unit regardless of its contents, so lines containing spaces or punctuation are quoted whole rather than being split apart.

Limitations

Does not add commas or other list separators between lines; only the quoting itself is handled.
Doesn't escape quote characters that already appear inside a line.

Examples

Quoting a short list

Input

apple
banana
cherry

Output

"apple"
"banana"
"cherry"

Each line is wrapped individually with the default double-quote character, and newlines are preserved between them.

Best Practices & Notes

Best Practices

Use Line Unquoter afterward to verify the operation is reversible for your text.
Combine with a find-and-replace or line-suffix tool afterward if you also need trailing commas for a code array.
Choose a quote character the text does not already contain, since nothing is escaped and an embedded quote will break the resulting literal.

Developer Notes

The implementation is `input.split("\n").map((line) => quote + line + quote).join("\n")`, which treats each line independently rather than the whole text as one block, unlike String Quoter.

Line Quoter Use Cases

Building a quoted array of values for code, one per line
Preparing line-delimited data for a format expecting quoted values
Converting a plain list into ready-to-paste string literals

Common Mistakes

Expecting list separators like commas to be added automatically; only quoting is applied.
Using a quote character that already appears inside the lines, which can make the result ambiguous to parse back.

Tips

Pair with Line Unquoter to reverse the operation if you need to strip the quotes back out later.
Blank lines come out as a pair of empty quotes, which is easy to overlook once the result has been pasted into a code array.
