@Salman_Alkweldy You need to transform the text dates in column H to real dates with Text-to-columns on the Data ribbon. Skip through steps 1 and 2 (i.e. change nothing). In step 3 set the data format to 'Date' and indicate that the texts are in 'DMY' format and Finish.
Now, Excel will transform the texts to real dates and display them in the default date format based on your local system settings.
