I have a csv file that has date data in dd/mm/yyyy hh:mm format. After importing the data into PowerBi, I click on the columns with the date data and change the type from Text to Date.
PBI recognizes some of the rows as dates but kicks out the above error. I have made sure I am in the right region.
I can convert the text type into date in excel with no problems.
Below is some sample data from a few data fields with nulls removed

Solved! Go to Solution.
Hi Team Tang,
I found the solution to the issue. I needed to select "Using Locale" when selecting to change the "Type". See below.
Hi @DeanNSP
I test it with your sample data, and it works fine on my side.
My operation process:
1. format data in Excel
2. get data from excel in Power BI Desktop.
Does it work if you try the same operation?

Do you know why this was the case? I know this is an old issue and probably not in your head, but I am curious.
thanks a lot, it works
It works with me. Thank you for the solution.
The data did not show up correctly here is a screenshot of data from PBI.
