# ArgMin

The ArgMin step allows you to get row(s) matching the minimum value in a given column. You can optionally specify to apply the step by group, i.e. get min row(s) by group.

### Step parameters

* `Search min value in`**\* (string)**: the column the minimum value will be searched in
* `Group by` **(array)**: array of one or several columns that will be used to constitute unique groups. Then the step will return min row(s) for every group)
