# is not empty

This block is part of the [`condition`](https://docs.rual.nl/block-types/condition) group and was last modified in core [`v10.4.28`](https://docs.rual.nl/core-versions/100428).

checks if the array is filled (not empty)

- Array required `array` The array to be checked.

- condition `condition` The condition that tells if the given array is filled (not empty).

True only when the array pin holds an actual array with at least one element; false for an empty array, nil, missing, or any non-array value - a non-empty string or object still outputs false.

A typical wiring for [is not empty](https://docs.rual.nl/block-types/condition/condition_not_empty_array): [cast to array](https://docs.rual.nl/block-types/type%20casting/file_convert_to_array) feeds the `array` pin; the `condition` out pin feeds [branch](https://docs.rual.nl/block-types/flow/branch).
