1. Autofill

Autofill is a core feature of Excel that provides great convenience during data entry.

Here are some common autofill data patterns: serial numbers, dates, times, quarters, nouns, and some custom repeated data.

2. Autofilling by Dragging

First, select A1 and A2 cells. When the mouse icon turns into a solid cross shape, drag it down to automatically generate sequential numeric entries.

Similarly, you can fill rows this way.

Note that if you only select A2, dragging down will only generate a series of the number 2. So if the autofill content doesn’t meet your expectations, try selecting multiple cells to trigger autofill.

3. Switching Fill Types When Filling Date Sequences

When filling in date data, we can also switch the type of dates being filled.

4. Quick Filling Data by Specifying Fill Quantity

When we have a large volume of data to fill, dragging can become cumbersome.

At this point, we can quickly fill data by specifying the fill quantity.

Under the Home tab in the Editing group, click on Fill, then select Series.

5. Defining the Final Value for the Fill

Here we choose the fill direction as: column, select the fill type as: linear, and then enter the final fill value as 8.

Click OK.

6. Results of the Fill

Here we achieve the same result as the drag fill, but save the dragging process.
