How do I change a columns date format to "MMM-YY" in Power Query?!

[Thad]

I need to transform a column from dd-mm-yyyy to mmm-yy before merging it with another column, so it has to happen in the query editor and not through a measure. 

How? Nothing I have tried worked. It can't be that difficult.

Thanks in advance.

Hi @Thad try with Capitalized M as below

Date.ToText([YourColumnForDate],"MMM-yy")

If not ok after that, check link what could be wrong with your case.

Hi @Thad ,

Please try the following methods and check if they can solve your problem:

1.Create the simple table.

2.Click the Transform data and add custom column.

= Text.From(Date.MonthName([Joining date]))&"/"&Text.From(Date.Year([Joining date]))

3.The result is shown below.

Hi @Thad try custom column in PQ

Date.ToText([YourColumnForDate],"mmm-yy")

[Thad]

Wish that was it. Unfortunately, this results in a 4-digit-value with no letters, e.g. 31.07.2022 becomes "00-22". May that be due to a wrong locale setting?

hi , share some sample please to see the type of the column and data  inside it 

[Thad]

The data comes in dd-mm-yyyy format as text.

I am now trying a workaround by extracting the name of the month from each row (after converting the column to date format, ofc), then keeping only the first three letters of that column and then merging it with the extracted year. If you have an easier way, I woudn't be mad.
