Handling two date formats

[Anonymous]

Hello,

I have a kinda big PowerBI file where about a dozen tables are based on one Folder of CSV files. The system providing these CSV files now switched the date column from DD.MM.YYYY to YYYY-MM-DD for new files.

Whats the best and easiest way to make it possible to handle both date formats so its no difference whether a new or old file is processed?

Harry.

Hi @Anonymous ,

According to your question, I think the conversion can be realized quickly in powerbi desktop. You can create a column on the desktop and use format to customize the date type. The format type to achieve a unified multi-file date is as follows:

If the problem is still not resolved, please provide detailed error information and let me know immediately. Looking forward to your reply.

Hi, @Anonymous 

Please correct me if I wrongly understood your question.

If each file has a different format type in the DATE column, then, in my opinion, the best way to deal with it is by using Power Query in Power BI and change it by using the option LOCALE. This will make all files have a standard format in the DATE column.

@Anonymous , bring them as text , Create a new column in dax and mark as date

if(search("-",[Column],,0) >0 , Date(left([Column],4) ,Mid([Column,4],6,2), right([Column],2)) ,

Date(right([Column],4) ,Mid([Column,4],4,2), left([Column],2)) )

In power Query you do have Start, Middle and end , in case you want to do in power query refer (index start from 0 there)
