How is this different from the string category's Line Quoter?

Line Quoter only splits on newlines. List Item Quoter accepts a configurable separator, so it can quote items in a comma-separated list or a custom-delimited list, not just one item per line.

Does this produce valid code, like a JSON or Python array?

It wraps each item in quotes but doesn't add surrounding brackets, commas between items unless you choose comma as your separator, or escape special characters inside the items. For a real code array, you may still need to add brackets and escape quote characters within items yourself.

Can I quote items that already contain quote characters?

Yes, but this tool does not escape any quote characters that already exist inside an item's text, it only adds the wrapping quote characters around the outside. If your items contain the same quote character you're wrapping with, the result may be ambiguous when parsed elsewhere.

List Item Quoter - Wrap Every List Item in Quotes

Overview

Introduction

Wrapping every item in a list with quotes is a common step when preparing a list for use as code, like a JSON string array or a CSV field.

This tool quotes every item in a list with your choice of single or double quotes.

What Is List Item Quoter?

A list transformer that wraps each item with a matching pair of quote characters, either " or '.

Unlike the string category's newline-only Line Quoter, this tool accepts a configurable separator for comma or custom-delimited lists too.

How List Item Quoter Works

The list is split into items using the resolved separator, and each item is wrapped with the chosen quote character on both sides.

The quoted items are rejoined using the same list separator to produce the final output.

When To Use List Item Quoter

Use it to quickly turn a plain list of words or values into quoted strings for pasting into code, like a JavaScript or Python array literal.

It's also handy for preparing quoted CSV fields or SQL `IN (...)` clause values.

Often used alongside List Item Unquoter, List Item Wrapper and Line Quoter.

Features

Advantages

Choice of single or double quotes to match your target format.
Works with any of the supported list separator modes.
Fast, consistent quoting applied to every item in one pass.

Limitations

Does not escape quote characters that already appear inside an item's text.
Doesn't add surrounding array brackets or a comma separator between items unless you choose comma separator mode.
Not a substitute for a proper code-generation or serialization tool if your items contain complex special characters.

Examples

Double-quoting a newline list

Input

apple
banana

Output

"apple"
"banana"

Each item is wrapped in double quotes, one item per output line.

Single-quoting a comma list

Input

red,green,blue

Output

'red', 'green', 'blue'

Comma separator mode quotes each item and rejoins with ", " for a Python-list-like result.

Best Practices & Notes

Best Practices

Check your items for embedded quote characters before quoting, and escape them separately if needed for your target format.
Use comma separator mode if you want a result close to a code array literal's comma-and-space item spacing.
Follow up with List Item Wrapper if you also need surrounding brackets like `[` and `]`.

Developer Notes

Implemented with `Array.prototype.map()` over the split item array, building each output entry as a template string `${quote}${item}${quote}` before rejoining with the shared `joinListItems()` helper.

List Item Quoter Use Cases

Preparing a plain list as a quoted array literal for code
Building quoted CSV field values from a plain list
Formatting values for a SQL `IN (...)` clause

Common Mistakes

Expecting embedded quote characters within an item to be automatically escaped; they are left as-is.
Forgetting that this tool doesn't add array brackets on its own; combine with List Item Wrapper if you need them.
Choosing a quote character that matches characters already inside the items, creating ambiguous output.

Tips

Chain with List Item Wrapper afterward to add surrounding brackets for a complete array-literal look.
Use List Item Unquoter to reverse this operation if you need the plain items back later.
