Join Array

What It Does

Combines all items in a list into a single text string, with a specified character or string between each item. This is useful for creating comma-separated lists, space-separated words, or any delimited text.

Inputs

Name	Description	Type	Required
array	The list of items to join together	List	Yes
delimiter	The character or string to insert between items	String	No

Outputs

Name	Description	Type
value	The combined text string with delimiters	String

How to Use It

1. Drag the Join Array node into your graph.

2. Connect a list (like ["red", "green", "blue"]) to the "array" input.

3. Set the "delimiter" to the character you want between items (like ", ").

4. Run the graph—your output will be a single string with the items joined ("red, green, blue").

Tips

• The default delimiter is a hyphen (-), but you can use any string, including spaces, commas, or even multi-character strings.

• Non-string items in the array will be converted to strings automatically.
