Final answer:
To replicate formatting using autofill, select the source range, use the fill handle to drag the formatting down to the target range, and release the cursor to apply the format to the new cells.
Step-by-step explanation:
To use autofill to fill the range C11:J15 with the formatting from the range C10:J10 in a spreadsheet program such as Excel or Sheets, follow these steps:
- Select the source range C10:J10 that contains the formatting you want to copy.
- Move your cursor to the bottom-right corner of the selected range until it turns into a small '+' sign, known as the fill handle.
- Click and drag the fill handle downward to fill the target range C11:J15 with the formatting. Release the mouse button when you have highlighted the correct range.
By doing so, the formatting from the cells in C10:J10 will be copied to each cell in the range C11:J15, without altering any existing content in those cells.
