Final answer:
To insert the current date and time in cell A1 in Excel, use the =NOW() formula, which updates dynamically, or use Ctrl + Shift + ; for the time and Ctrl + ; for the date to insert static values.
Step-by-step explanation:
To insert the current date and time in cell A1, you can use a simple formula in Excel. Here is a step-by-step guide:
- Open your Excel spreadsheet.
- Click on cell A1 to select it.
- Type =NOW() into the formula bar and press Enter.
The =NOW() formula will automatically populate cell A1 with the current date and time. Every time the worksheet recalculates, this cell will update to the most recent date and time. To avoid automatic updates and keep the date and time static, you can use the keyboard shortcut Ctrl + Shift + ; (semicolon) for the current time and Ctrl + ; (semicolon) for the current date.
