When building a rating file, Excel may interpret a numeric range containing a hyphen as a date. For example, entering 4-7 could cause the cell to display 04-Jul.

How to prevent this

Enter the range using decimal values:

• Incorrect: 4-7
• Correct: 4.0-7.0

Using decimals helps ensure the value remains a numeric range rather than being automatically reformatted as a date.

Before uploading your rating file, check that all ranges display correctly and have not been converted into dates.
