Import Data (SSAS Tabular)


You can import data into a tabular model from a wide variety of sources. The topics in this section describe how to use the Data Import Wizard to connect to and select data to be imported into a model project.


If any of the tables in your model will contain a large number of rows, consider importing only a subset of the data during model authoring. By importing a subset of the data, you can reduce processing time and consumption of workspace database server resources.

Using the Table Import Wizard, you can import data from the following data sources:

Data Source


Relational Databases

Relational Data Sources include:

  • Microsoft SQL Server

  • Microsoft SQL Azure

  • Microsoft SQL Server Parallel Data Warehouse

  • Microsoft Access

  • Oracle

  • Teradata

  • Sybase

  • Informix

  • IBM DB2


Multidimensional Sources

Microsoft SQL Server Analysis Services cube

Data Feeds

Data feeds include:

  • Microsoft Reporting Services Report

  • Azure DataMarket Dataset

  • Atom feeds from a public or corporate provider

Text Files

Text files include:

  • Excel files (.xlsx)

  • Text file (.txt)

In addition to importing data by using the Table Import Wizard, you can paste copied data (from Clipboard) into a table. Pasted data behaves differently from data that has been imported from other data sources. Pasted data in tables do not have a Connection Name or Source Data property. Pasted data is persisted in the Model.bim file. When the project or Model.bim file is saved, the pasted data is also saved.
