A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data.
I suspect that you are talking about a CSV file, not an Excel file (xls, xlsx, xlsm or xlsb).
In an Excel file, dates are represented by an integer. For example, enter the date 9/1/2022 into A1, then enter formula =A1 into A2 and format A2 as General. You will see 44570 if the system date form is DMY. You will see 44805 if the system date form is MDY.
Suppose you see 44570 in A2. You will continue to see 44570 in A2 even if you reformat A1 to display m/d/yyyy.
When the Excel file is saved as CSV, the characters 9/1/2022 are written to the file, not the integer.
If you open the CSV file on a computer where the system date form is MDY, A2 will display 44805.
If you open the CSV file on a computer where the system date form is DMY, A2 will display 44570.
Practically speaking, there is nothing you can do about that.
You need to format dates as they will be interpreted on the receiving system before you save as CSV.
