Importing a .dbf (dBase) file into Power BI

How can I import data from a .dbf (dBase) file into Power BI?

Today’s Power BI Mailbag Question comes from a friend who often works with geospatial data and, as a result, ends up with several different shapefile formats, including .dbf (dBase) database table files. There are several blog articles around shapefile mapping options in Power BI, but this question of accessing the .dbf file directly from Power BI was something I hadn’t been asked before.

Note: Power BI does not have native .dbf file support at the time of publishing this article, but the idea has been proposed at ideas.powerbi.com if you would like to vote for it. 

When I began searching for a solution, I found several threads in the .NET provider MSDN forum showing how to leverage the Access OLEDB provider (Microsoft.ACE.OLEDB.12.0) to import data from a .dbf file into SQL Server. With this, we can use a similar solution in Power BI. 

Data Source (Rainfall in Ethiopia):
For this example, I’m using a .dbf file containing the rain statistics in towns in Ethiopia from worldbank.org.

Steps:
In Power BI Desktop, click on Get Data -> Blank Query

Click on the Advanced Editor and replace the default text with the following text (replacing with your path and dBase file name):

let
    Source = OleDb.DataSource("Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\Blog\DBF\;extended properties=dBASE IV", [Query="select * from [rain.dbf]"])
in
    Source

 

 

This will prompt you to edit the credentials. Click "Edit Permissions" to continue.

 

 

Another prompt appears asking to approve of running the native query against this data source. Since the OLEDB provider syntax we provided contains the query string, you need to approve that this can be executed against the .dbf file. Click Run to continue.

 

 

You may get one additional dialog box requesting proper credentials as I did with some other data sources I used in testing this solution. I selected the “Default or Custom” option with no value supplied in the connection string property dialog. 

 

 

With this, the data will be loaded into Power BI and you can continue with your report creation.

 

 

 

 

Special thanks to Aaron Bator for constantly pushing the edges of Power BI and bringing new and innovative ideas and questions. Keep them coming!

Thanks,

  Thanks, dBase support.and I hope to support dBase as Power BI's data source for more easy operation.

  Hi, I have followed your post but am having issues connecting to my dbf file. Basically beacuse it's giving me a "DataSource.Error: OLE DB: External table is not in the expected format" It seems to be happening because the fpt file is a seperate file. How can i link them please?

    Hi Jorge, can you do a quick test to rename the file to a name that is <= 8 characters? I hit an issue with the driver when the filename prior to the .dbf extension is greater than 8 characters.Thanks,Sam

  Sam, tried to follow your example - downloaded the Ethiopia rain statistics (it is named eth_rainst.dbf) , and used the connection string you have, but I get this error - DataSource.Error: OLE DB: Could not find installable ISAM.Details: DataSourceKind=OleDb DataSourcePath=data source=C:\Users\martintse\Desktop\Temp;extended properties="dBASE IV";provider=Microsoft.ACE.OLEDB.12.0 Message=Could not find installable ISAM. ErrorCode=-2147467259Tried, OleDB 15, dbase 5.0, but still no go - can you check if this still works for you?

    Hi Martin, I just tested it out and it is still working for me without the error you posted. One thing I did encounter testing it out is that there appears to be an 8 character filename limitation with this driver. In the original blog, I'd unintentionally worked around this by renaming the file to rain.dbf. When I just tested it out with the downloaded file name, I was receiving an error that the file didn't exist since it was greater than 8 characters. Renaming the file and updating the connection string fixed this.

  Thank you Sam for this useful tutorial. I searched for an answer and this is exactly what I needed. If others have trouble I think the key is to start here:Click on Data Tab.Go to the following "New Query -> From Other Sources -> Blank Query"Follow directions directly after steps, make any necessary changes in the SQL code and should be good to go.

  Thank you Sam. This works perfectly.Getting Started Tip for others with Excel 2016:Click on Data -> New Query -> From Other Sources -> Blank QueryDon't forget to change the file path and file name in the Query 1 Code

  Tried the Ethiopian example: does not work with the following error:DataSource.Error : OLE DB : The Microsoft Access database engine could not find the object 'eth_rainst.dbf'. Make sure the object exists and that you spell its name and the path name correctly. If 'eth_rainst.dbf' is not a local object, check your network connection or contact the server administrator.Détails : DataSourceKind=OleDb DataSourcePath=data source=C:\Users\meller\Downloads\eth_rainst_0;extended properties="dBASE IV";provider=Microsoft.ACE.OLEDB.12.0 Message=The Microsoft Access database engine could not find the object 'eth_rainst.dbf'.

  Hi Sam, I am trying to connect Power BI to my company´s (very outdated) ERP data base which is in .dbf files, while following this instructions I got the following error:DataSource.Error: An error happened while reading data from the provider: 'The 'Microsoft.ACE.OLEDB.12.0' provider is not registered on the local machine.'Details: DataSourceKind=OleDb DataSourcePath=data source="C:\Users\Pc\Desktop\PRUEBA DATOS";extended properties="dBASE IV";provider=Microsoft.ACE.OLEDB.12.0The same error displays while trying to connect to the example files of the ethiopian weather DB, do you have any idea or suggestion about how can I solve this?

    Hi Martin, when I've hit a similar error (Microsoft.ACE.OLEDB.12), the issue was an architecture mismatch where you have 32-bit data providers and the app needs 64-bit (or vice versa). Check out this post in the Power BI community to see if it can help you narrow it down. If that doesn't do the trick, you may want to post to the Power BI community forum for some additional assistance. Good luck!https://community.powerbi.com/t5/Desktop/quot-Microsoft-Access-The-Microsoft-ACE-OLEDB-12-0-provider-is/td-p/109184

  I was too impatient for all this. So I just created a blank Access file (.accdb) and created a linked table pointing to the .DBF.Then used the .accdb file as my data source. The .mdb data flows right through. Took 30 seconds. Done.
