Update a Dataset with New Data


Use this article to update an existing dataset with a new version.


Data is always changing. Even if you just imported data into Paxata®, there’s a chance the data is outdated. Updating the data in a dataset allows you to import a dataset as a new version of an existing dataset. After you update a dataset, you can easily use the new version in an existing Project. See the Update the Project Datasets article for more information.

When updating a dataset, you can chose to update to a dataset where:

  • Only the values have changed - the structure and format are the same.
  • The format or structure changed - e.g. column added or removed.
  • A completely different dataset - new values, new structure and format.
