Inconsistency with Power Query

[Anonymous]

Hi,

I have the next problem:

When I load some datas from an Excel file, in Power Query the dates are perfect, but when I upload to Power BI desktop some dates are deleted and I dont know why.

These are some pictures of this problem:

One option for fixing the sorting issue is to create another column where dates are represented in "2020-12-31" format and to use that for sorting.

Hi, @Anonymous 

Based on your description, I'd like to suggest you create an index column in data scource. Then you may go to 'Modeling' ribbon, click 'Sort by column', make the index column selected.

Best Regards

Use locale to set the date format.

Refer to this post.

Ok, I change the typo to locale (united Kingdom)

But the dates are not in the same order as in the excel, and is very important the order.

Do you know how to fix that?

Thanks

I would say, introduce a column with seriel no(or index) in excel and bring that to Power BI. You could use that column as a SORT BY column for date.

Are they deleted or in a different order. Check no of rows.

Another issue. When you have a date in DD/MM/YYYY, sometimes it happens that few dates are taken as MM/DD/YYYY. Just check for that too

The n° of rows are the same, How can I solve that problem with the order of the format of the dates?

[amitchandak]

There are few options like you try to the system that date is in the British format. If nothing works out. Then convert it into text. Check the date are the same as the source.

and create a new column like

new column = mid(DD__MM__YY[Date],4,2) &"/"& left(DD__MM__YY[Date],2) & "/" & right(DD__MM__YY[Date],4)
