Edit dataset

When editing a dataset, you can manage data sources, columns, calculations, joins, and so on. If the dataset that you edit is used in a visualization, the visualization is updated after the refresh. If the dataset is shared, it is updated for all the recipients. If the dataset is certified, it becomes uncertified.

If you need to update only the content of a data source file, see Reupload files of a dataset.
