Append queries (Power Query)

Important   This article applies to Power Query, a data analysis feature available for Excel that lets you discover, combine and refine data. You may need to enable Power Query in Excel. You can also download and install the most recent version of Power Query for Excel, which automatically enables it. Power Query technology is also built into the Power BI Designer, which is a stand-alone report authoring and data transformation tool for Power BI.

In Power Query, the Append operation creates a new query that contains all rows from a first query followed by all rows from a second query.

Security   Privacy Levels prevent a user from inadvertently combining data from multiple data sources, which may be private or organizational. Depending on the query, a user could inadvertently send data from the private data source to another data source that might be malicious. Power Query analyzes each data source and classifies it into the defined level of privacy: Public, Organizational, and Private. For more information about Privacy Levels, see Privacy Levels.

Perform an Append operation

You can perform two types of append operation: Intermediate Append or Inline Append. With Intermediate Append, you create a new query for each append operation. With Inline Append, you append data into your existing query until you reach a final result. The result is a new step at the end of the current query.

Inline Append

  1. In Query Editor, in the query Preview grid, click the table icon (Table icon) and click Append Queries....

    Remove errors menu - Query Editor

Intermediate Append

  1. In the POWER QUERY or Query Editor ribbon, in the Combine group, click Append. When using the Query Editor ribbon, the active query is selected as the primary table for the Append operation.

  2. In the Append dialog box, select the first and second tables (queries) to append.

  3. Click OK.

    Once the Append operation completes, Power Query displays a new query in the query editor.

To view the Query Editor without loading or editing an existing workbook query, from the Get External Data section in the Power Query ribbon tab, select From Other Sources > Blank Query.
