Bug report

When importing from Excel in Spreadsheet if a date is entered, but the date format is not set explicitly, the imported date always has the following format: "mm-dd-yy". The issue is observed even if a culture is set.

Reproduction of the problem

1. Open the Dojo example
2. Import the following file DateFormat.xlsx

Current behavior

The value in Excel is "15.6.2020" , but the imported date in the Spreadsheet is "06-15-20" screencast

Expected/desired behavior

The format of the dates should be the same as in the imported file.

Environment

• Kendo UI version: 2023.3.1114
• Browser: [all ]
