The Excel feature that automatically inserts the next month in a series beginning with January is called "Fill Handle." Here's how you can use it:
1. Enter "January" in a cell.
2. Click on the cell to select it.
3. Move your cursor to the bottom-right corner of the selected cell until it turns into a black cross, known as the Fill Handle.
4. Click and drag the Fill Handle across the cells where you want the months to be filled.
5. Release the mouse button, and Excel will automatically fill in the subsequent months (February, March, April, and so on) in the series.
By using the Fill Handle feature in Excel, you can quickly populate a series of months or other data without having to manually type each entry, saving time and effort in your spreadsheet tasks.
