2. Select a cell where the result should appear.
3. Type =ISBLANK(A1) in the formula bar.
4. Press Enter to confirm the formula.

Success Criteria

Tips While Using

• Common mistake: If the reference is incorrect, the formula checks the wrong cell.

2. Check whether a referenced cell is blank

Entry point: Worksheet cell → formula input

1. Identify the target cell you want to test, such as B2.
2. Select a result cell and enter =ISBLANK(B2).
3. Press Enter to view the result.
4. Use the result to determine whether the target cell is blank.

Success Criteria

• On-screen result: A blank target cell returns TRUE, and a non-blank target cell returns FALSE.
• Next action available: You can copy the formula to other rows or columns.

Tips While Using

• Common mistake: A cell that contains text is sometimes mistaken for a blank cell, which causes FALSE.

3. Combine ISBLANK with IF

Entry point: Worksheet cell → formula bar

1. Select a result cell.
2. Enter a combined formula such as =IF(ISBLANK(C2),"Not filled","Filled").
3. Press Enter to confirm.

Tips While Using

• Common mistake: Incorrect quotation marks, parentheses, or commas can cause a formula error.
