Summary  
This chapter covers automating repetitive data population using pattern-based series generation (AutoFill) and template-driven pattern recognition (Flash Fill), along with basic cell editing and reversible operations via undo/redo.

General domain of usage  
Spreadsheet data management

Efficient data entry is crucial for using Excel effectively. While basic text and number entries are straightforward, Excel's powerful features like **AutoFill** and **Flash Fill** save time by automating data patterns and extending series like numbers or dates. 

AutoFill may work unexpectedly, especially with dates—it can increment months or years instead of days. To ensure it follows your desired pattern, manually enter the first two dates (e.g., **01/01/2024**, **01/02/2024** for daily increments). Then, select both cells and drag the AutoFill handle to apply the correct sequence. This method helps Excel recognize the intended pattern and prevents unwanted changes in months or years.
