Office script to refresh all data connections of the workbook not working

Posted on by Ganesha B

Hi experts,

I have used the Office script to refresh all data connections of the workbook. The workbook uses the OLEDB connection to the Power BI dataset.

function main(workbook: ExcelScript.Workbook) {
    workbook.refreshAllDataConnections();
}
 

But while running this script via Power Automate, I get the following error.

some hints please...

Hi @BG-05051400-0,

Since you're trying to refresh a PBI connection, it should work: the refreshAllDataConnections method usually fails when called from Power Automate, except for PBI connection.

I found this old thread that is related to the same issue: https://community.powerplatform.com/forums/thread/details/?threadid=f7869112-0b26-47f9-b709-9e2befa916b6. According to the accepted answer, it looks like a temporary issue.

Let me know if it works for you or if you need any additional help!

@BG-05051400-0 Hi,

I don't think you can use OLEDB connection on excel online. (I might be wrong, I cannot find any doc that support OLEDB)

If Power BI source doesn't belong to current tenant, you may consider using Odata query . for example.

Using the Power BI REST APIs.

Hi All,

thanks for all your response.

I saw this documentation, and it states that Workbook.refreshAllDataConnections only refreshes when PowerBI is the source.

Troubleshoot Office Scripts running in Power Automate - Office Scripts | Microsoft Learn

I also use the PowerBI dataset with the OLEDB connection. So I guess it should support in my case. Any suggestion here?

Regards,

Ganesha

Hi @BG-05051400-0,

Your conclusion is correct: the general rule for the refreshAllDataConnections is not to work from Power Automate, except when the connection has PBI as source. So it should work for your case, in my understanding.

I'm not very familiar with the connection between PBI and Excel for loading data to the spreadsheets, but I wonder if there are any other methods besides the OLEDB to perform this connection. If yes, this might be the problem: PBI works with these alternative methods, but not with OLEDB.

Anyway, the Office Scripts development team is very active in GitHub, so I recommend you to open an issue there to share about this problem. Eventually they can recommend some workaround. You can open the issue here: https://github.com/OfficeDev/office-scripts-docs/issues?q=is%3Aissue%20state%3Aopen

Let me know if it works for you or if you need any additional help!
