A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data.
If you enter . it will be interpreted as a decimal point. 14.55 is treated as 14 days and 55/100 of a day. 55/100 corresponds to 13:12. You must use : as separator when you enter time (unless you use VBA to convert 14.55 to 14:55).
You can create your own custom time format:
- Select a range of cells.
- Click More Formats... in the number format drop-down on the Home tab of the ribbon.
- Select Custom in the Category list.
- Enter your preferred format in the Type box.
- Click OK.
See Format numbers as dates or times for the format codes you can use.
