Excel importing date inconsistently from Csv

Question

I have a .csv file delimited with ; (semicolon) generated from PHP code. It has three columns that contain date in dmy format(eg. 23 Apr 2013).

But when imported it in Excel,these date value become inconsistent.

It shows two different formats:

12 Oct 2006
15. Feb 06

In the .CSV , the format is same as that of 12 Oct 2006.

I have tried making them consistent by selecting the whole column and changing a single format. But it doesn't work.

Answer 1

It's because of different language of your Excel.

for example:

In deutsche

 23 Oct 2017

In English

 23 Okt 2017

So it will not understand Oct if you are using deutsche language with your excel.

same for English language it will not understand Okt .
