Chapter 45: Flash Fill in Excel

Flash Fill is a powerful feature in Excel that automatically fills in values based on a pattern you provide. It simplifies data entry tasks by detecting patterns and applying them across a range of cells. This chapter will walk you through how to use Flash Fill with various examples.

Using Flash Fill

1. Activating Flash Fill:

Flash Fill is enabled by default in Excel. To use it:

1. Start typing the pattern or example in a cell.
2. Press Enter after typing the example.
3. Move to the next cell and start typing the pattern again.
4. Excel will automatically suggest the rest of the data based on your example.
5. Press Enter to accept the suggestions or Esc to reject them.
