Sort Columns

In this document, you will explore how to sort columns in Astera Dataprep.  

1. To sort columns in Astera Dataprep, click on the Layout option in the toolbar and select the Sort Columns option from the drop-down. 

1. Once selected, the Recipe Configuration – Sort Columns panel will open.

1. In this panel:

• Optional checkboxes allow you to customize the sort behavior:

  • Treat Null as the Lowest Value: Places null values at the beginning of the sort.

  • Case Sensitive: Enables case-sensitive sorting.

  • Return distinct values only: Returns only unique rows in the sorted output.

• Use the Field drop-down to select the column you want to sort.

• The Sort Order options include:

  • Ascending: Sorts the column from A to Z or smallest to largest.

  • Descending: Sorts the column from Z to A or largest to smallest.

1. Click Apply to sort the dataset. The Grid will now reflect the specified sort order. For example, sorting the StoreName column in ascending order.

1. Alternatively, you can sort a column directly in the Grid by right-clicking on the column header and selecting Sort Columns from the menu. This opens the Recipe Configuration panel with the selected column pre-filled. Adjust the settings if needed and click Apply to confirm.
