I am trying to export a matrix into a .CSV file which has dates with format: Year/Month/Day.

When I try to export it into a CV those cells are converted into Day/Month/Year

When I try to export it into a Excel file those cells are printed as Year/Month/Day (literaly the same thing that is in the matrix.)

I have no argument in the exporting command. I just write:

Export["path_to_file.csv", output]

The funny thing is that yesterday I think the code was running correctly...

Any idea what is the problem?

Thank you!

Apparently what happens is the excel changed the formating. If I open the file with notepad it is year/month/day.

Sorry for the trouble.
