Here is a step-by-step guide to using the AutoFill feature in Excel:

  1. Enter data in the first cell of a series
  2. Drag the fill handle of the cell down or to the right, depending on the direction of the series
  3. Release the mouse button to fill the series
  4. To fill with an increasing series like dates or numbers, hold down the control key while dragging
  5. For custom lists, create them beforehand in the options dialog box (File > Options > Advanced > General > Edit Custom Lists)

Reasons why AutoFill may not work as expected

AutoFill feature in Excel can sometimes fail to work as expected, causing unnecessary frustration for users. Here are some reasons why AutoFill may not function efficiently:

  • Cell format: AutoFill may not function correctly if cells are not formatted correctly, especially when dealing with dates and times. Ensure that the cells are formatted correctly before using AutoFill.
  • Hidden cells: If hidden cells are included in the range, Excel may not fill the data to the required cells. Make sure there are no hidden cells within the selected range before using AutoFill.
  • Non-adjacent cells: AutoFill in Excel only works on adjacent cells. If you try to fill non-adjacent cells, the feature may not function properly.
  • Insufficient data: If there isn’t enough data in the selected range, AutoFill won’t work. Ensure there is enough data in the range before using AutoFill.

It is also essential to note that when using AutoFilling with the Alphabet in Excel, starting a cell with an uppercase letter may cause issues with the feature’s functionality.

A Pro Tip for users is to double-click the small square at the bottom-right corner of the cell containing the data you wish to auto-populate. Doing so will prompt Excel to fill the data to the desired cells automatically.
