Issues when source date column contains Date and Serial date

Hi all,

 

This is my first question to the forum, so be gentle...

 

I'm relatively new to Power BI and have a bunch of CSVs i'm consolidating into a report. Occasionally one of the date columns contains serial format (e.g., 45678) dates. At the same time, this column also contains dates (correctly) in the format dd/mm/yyyy. Example shown here.

In Query Editor, when i try to reformat the column to "Short Date", it doesn't do anything and i'm still presented with "Error - We couldn't parse the input provided as a Date value". In the CSV file, the serial is coming through as "General" format. But the same error happens if the serial is "Number". 

 

Replace Errors won't help, because I want to keep the underlying date, and don't want to replace it with a static value because there could be other reasons for errors in this column too, not just the serial date format. 

 

Any help would be appreciated!

 

Thanks

Adam

Hi,
If no transformation works, you could create a new column by using:

#date(1900,1,1)+#duration([Column4]-2,0,0,0)
