How to use List to JS Array

Paste your list, choose the delimiter and quote style, toggle trim / skip-empty / dedupe / multiline, then click Generate Array and copy the literal.

Frequently asked questions

What delimiters are supported?

Split by newline, by comma, or by any whitespace. Each resulting item becomes one element of the generated array.

How are values quoted?

Pick single or double quotes and each item is safely escaped for that quote. Choose None to keep raw values such as numbers or booleans unquoted.

Can it remove duplicates?

Yes. Enable De-duplicate to keep only the first occurrence of each item, and Skip empty to drop blank lines before building the array.
