Part 2 — Tips That Save Time
🔹 Tip 11: Use Flash Fill
When Excel recognizes a pattern, press: Ctrl + E
📌 Great for splitting, combining, or reformatting text without writing formulas.
🔹 Tip 12: Quickly Insert a New Line Inside a Cell
Press: Alt + Enter
📌 Useful when you need multiple lines of text within one cell.
🔹 Tip 13: Select Only Visible Cells
After filtering data, press: Alt + ;
📌 This selects only visible cells, preventing you from accidentally modifying hidden or filtered-out rows.
🔹 Tip 14: Use Absolute References When Needed
If a formula needs to always refer to the same cell or range, use $.
Example: =B2*E1
📌 E1 remains fixed when you copy the formula.
🔹 Tip 15: Quickly Copy a Formula Down
Double-click the fill handle (small square at the bottom-right of the selected cell).
📌 Excel automatically fills the formula down alongside the neighboring data.
🔹 Tip 16: Use Ctrl + 1 to Open Format Cells
Instead of navigating through menus, press: Ctrl + 1
📌 Quickly change number formats, alignment, borders, protection, and more.
🔹 Tip 17: Use SUM() with AutoSum
Press: Alt + =
📌 Excel automatically suggests a range and inserts a SUM() formula.
🔹 Tip 18: Quickly Create a Chart
Select your data and press: Alt + F1
📌 Excel creates a chart directly on the current worksheet.
🔹 Tip 19: Use Ctrl + Shift + $ for Currency Format
Select the values and press: Ctrl + Shift + $
📌 Quickly applies currency formatting.
🔹 Tip 20: Use Named Ranges for Important Data
Instead of repeatedly using ranges such as B2:B1000, give the range a meaningful name.
Example: SalesData
📌 Formulas become easier to understand and maintain.
