Dataverse Excel Import: Resolving the Microsoft ACE OLEDB 12.0 Error

Excel data import is a staple for many businesses and organizations. One common challenge faced by users is the “Microsoft ACE OLEDB 12.0 is not registered” error when trying to import an Excel file to Dataverse. In this blog, we’ll delve into what causes this error and offer a reliable solution to tackle it.

Often, when you’re working with the Dataverse platform and aim to transfer an Excel spreadsheet from OneDrive, you might stumble upon this error. The exact message might be:

DataSource.NotFound: Excel Workbook: The ‘Microsoft.ACE.OLEDB.12.0’ provider is not registered on the local machine. The 64-bit version of the Access Database Engine OLEDB provider may be required to read this type of file.

It can be exasperating, especially when the recommended steps, like downloading the client software, don’t resolve the problem. So, what can you do?

The root cause is often simpler than one might think. The issue typically arises from the source spreadsheet being in the older Excel XLS format, which was the standard for Excel versions ranging from 97-2003. The current Dataverse import mechanism isn’t compatible with this older format.

Solution

Convert the spreadsheet to the newer XLSX format. Once done, try the import process again. More often than not, this simple step resolves the problem.

The ACE OLEDB 12.0 Error often impedes users during Dataverse Excel data imports. Conversion to XLSX is a key solution.
