# Extract from array[¶](https://doc.dataiku.com/dss/latest/preparation/processors/array-extract.html#extract-from-array "Permalink to this headline")

This processor extracts an element or a sub-array from an array (written in JSON).

If a specified index is negative, it is counted from the end of the array: (-1 is the last value, -2 is second to last, etc).
