Module:CSVToBulletList

Module:CSVToBulletList

Converts a comma-separated string into a wikitext bullet list. Each comma-delimited value becomes its own `*` list item, with surrounding whitespace trimmed.

Usage

{{#invoke:CSVToBulletList|main|Item 1, Item 2, Item 3}}

Output:

* Item 1
* Item 2
* Item 3

Parameters

main

1

A comma-separated string containing the items to convert into a bullet list.

Notes

• Empty items are ignored (e.g. `A,,B` becomes `A` and `B`).
• If the input contains no commas, it will still be returned as a bullet list with a single `*` item.
