HTTP & JSON jsonJoinArray

$jsonJoinArray[]

Joins all elements of a JSON array into a single string using the specified separator.

Syntax

$jsonJoinArray[key;separator]

Parameters

Parameter	Type	Required	Default	Description
key	string	check_circle Required	—	The key identifying the JSON array to join. The key must exist and contain an array.
separator	string	check_circle Required	—	The string to insert between each element. Can be any text including spaces, symbols, or HTML.

Return Value

string

A single string with all array elements concatenated, separated by the given separator. Returns an empty string if the array is empty.

$jsonJoinArray combines all elements of a JSON array into a single string with a separator between each element — equivalent to JavaScript’s Array.join(). This is the inverse of $jsonArray which splits a string into an array. Use \n for line breaks in embeds, or custom separators like bullets or HTML tags.

Examples

Comma-separated list

$jsonParse[{"tags":["bot","automation","discord"]}]
Tags: $jsonJoinArray[tags;, ]

Line-break separated for embeds

$jsonParse[{"players":["Alice","Bob","Charlie"]}]
$title[Leaderboard]
$description[$jsonJoinArray[players;\n]]

Custom HTML separator

$jsonParse[{"items":["apple","banana","cherry"]}]
Shopping list: $jsonJoinArray[items; • ]
