Can I use a prefix without a suffix, or vice versa?

Yes, either field can be left empty as long as the other one has content, so you can use this purely as a prefix adder or purely as a suffix adder if that's all you need.

How is this different from List Item Quoter?

List Item Quoter always wraps items with the same character on both sides (a matching quote). List Item Wrapper is more general: the prefix and suffix are two entirely independent strings, of any length, so you can wrap items in brackets, HTML-like tags, or any custom text.

Can prefix and suffix be multi-character strings?

Yes, both can be any length, so you could use a prefix like " " and a suffix like " " to wrap each item in simple tag-like markup.

List Item Wrapper - Add a Prefix and Suffix to Every List Item

Overview

Introduction

Sometimes wrapping every item in a list needs more than a matching quote pair, brackets, parentheses, or even short tag-like markup on each side.

This tool wraps every item with a prefix and a suffix string you define independently.

What Is List Item Wrapper?

A list transformer that prepends a prefix string and appends a suffix string to every item in a list.

It works with newline, comma, or custom-delimited lists, and either the prefix or suffix can be left empty if you only need one side wrapped.

How List Item Wrapper Works

The list is split into items using the resolved separator, and each item is rebuilt as `prefix + item + suffix`.

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

When To Use List Item Wrapper

Use it to wrap list items in brackets, parentheses, or quotes-like markers for a code array or display format.

It's also useful for wrapping items in simple tag-like text, such as a prefix of "<li>" and suffix of "</li>", for quick pseudo-markup.

Often used alongside List Item Unwrapper, List Item Quoter and List Item Bullet Adder.

Features

Advantages

Prefix and suffix are fully independent, supporting any combination of wrapping characters.
Works with prefix-only or suffix-only wrapping if that's all you need.
Works with any of the supported list separator modes.

Limitations

Applies the exact same prefix and suffix to every item; it doesn't support per-item conditional wrapping.
Doesn't validate that the result is well-formed markup if you use tag-like prefix/suffix strings.
Requires at least one of prefix or suffix to be non-empty, otherwise there's nothing to wrap with.

Examples

Wrapping items in parentheses

Input

a
b (prefix: "(" suffix: ")")

Output

(a)
(b)

Each item gets the prefix prepended and the suffix appended.

Prefix-only wrapping

Input

task one
task two (prefix: "-> " suffix: "")

Output

-> task one
-> task two

Leaving the suffix empty applies only the prefix to each item.

Best Practices & Notes

Best Practices

Use List Item Quoter instead if you just need a simple matching quote character on both sides.
Keep prefix/suffix short and predictable if you plan to reverse the operation later with List Item Unwrapper.
Preview a small sample list first when using multi-character prefixes or suffixes to confirm the exact spacing you want.

Developer Notes

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

List Item Wrapper Use Cases

Wrapping list items in brackets or parentheses for a code array
Adding simple tag-like markup around each item for lightweight pseudo-HTML
Building consistent prefix/suffix decorated labels from a plain list

Common Mistakes

Leaving both prefix and suffix empty, which the tool rejects since there's nothing to wrap with.
Forgetting the exact prefix/suffix strings used, making it harder to reverse the operation later with List Item Unwrapper.
Expecting generated tag-like markup to be validated as well-formed; it's plain string concatenation only.

Tips

Use List Item Unwrapper afterward if you need to strip the same prefix and suffix back off later.
Combine with List Item Quoter first if you want both quoting and additional bracket-style wrapping.
