I have added excel files to ArcMap numerous times without any problem and then joined them to shapefiles, but, for some reason, today I am getting an error I have never seen before.

The error reads:

Could not add the specified data object to the map. AN underlying error occurred. Class not registered.

Has anyone else ever had this issue and managed to resolve it?

  • I have just tried in QGIS as well and it works fine here, but not in ArcMap

    What versions of ArcMap and Excel? When asking a question, always remember to include the version of the software you are using.

I have manage to resolve this by downloading the following and then joining using the Data Management in the Toolbox


This download will install a set of components that can be used to facilitate transfer of data between 2007 Microsoft Office System files and non-Microsoft Office applications.
