Combine array of strings
Combine entries in an array of string into one string
“Combine array of strings” allows you to combine entries in an array of string into one string.
On this page, we will introduce the Tool step to “Combine array of strings”.
How to use “Combine array of strings” step
Add the component
Add the “Combine array of strings” step to your Tool (check how to get started with
creating a tool).
Array to join
A “Combine array of strings” step requires an array of strings as an input. This array can be entered within the step.
However, it is often more practical to fetch the value from an input component (e.g. List input) or
another step output (e.g. JavaScript snippet producing a list of string).
Use {{variable name}} to provide the data to the “Combine array of strings” step.
Separator
Even though called separator, this field receives a character to be used as the connector of the items in the string array. For instance, with a ’-’ connector, all the list elements are stacked together with a ’-’ in between.
