.DQY File Extension

Most Excel users will not create or open DQY files. However, advanced users looking to import data from a database may create and open DQY files since they are useful for saving queries to be used again.

To create a DQY file with Query Wizard or Microsoft Query in Excel 365, follow these steps:

1. Select Get Data in the Data tab
2. Choose From Other Sources → From Microsoft Query
3. Verify that the "Use the Query Wizard to create/edit queries" checkbox is checked in the "Choose Data Source" dialog
4. Select the data source, click OK, choose the database you want to query, and define the query

DQY files created with the Query Wizard or Microsoft Query in Excel 365 are saved in the following location, by default:

C:\​Users\​[username]\​AppData\​Roaming\​Microsoft\​Queries

NOTE: DQY files are primarily used by Excel 2007 to 365 users.

You can open DQY files with Microsoft Excel in Windows and macOS. There are several ways to open a DQY file.

To open the query directly from Excel 365:

1. Select Get Data in the Data tab
2. Choose From Other Sources → From Microsoft Query
3. Click the "Queries" tab in the "Choose Data Source" dialog, select the query, then click Open

To open the query directly from Microsoft Query (included with Excel), select File → Open....

NOTE: You can also select File → Open and choose the DQY file in Excel 365 or double-click a DQY file if it is associated with Excel. These options will run the query and insert the data into a new worksheet.
