Running macros in Excel - Cell-by-Cell Formula Trace

Concept Flow

Start -> Read cells A1, A2, A3 -> Calculate sum -> Write sum to B2 -> End

The macro starts by reading values from cells A1, A2, and A3. Then it calculates their sum. Finally, it writes the sum into cell B2.

Formula

Sub SumValues() Dim total As Double total = Range("A1").Value + Range("A2").Value + Range("A3").Value Range("B2").Value = total End Sub

This VBA macro reads the values in cells A1, A2, and A3, adds them together, and writes the result into cell B2.

Step-by-Step Trace

Step	Action	Result	Explanation
1	Read values from A1, A2, A3	10, 20, 30	Macro reads the numbers in cells A1, A2, and A3.
2	Calculate sum = 10 + 20 + 30	60	Macro adds the three numbers to get the total sum.
3	Write sum 60 into cell B2	B2 = 60	Macro places the sum result into cell B2.

Macro completes after writing the sum to B2.

What does the macro do with the values in cells A1 to A3?

A Adds them together and puts the result in B2

B Multiplies them and puts the result in B3

C Copies the value from A1 to B2

D Clears the values in A1 to A3

Key Result

A macro can automate tasks by reading cell values, performing calculations, and writing results back to the sheet.

Transcript

We start by reading the numbers in cells A1, A2, and A3. The macro adds these numbers together to get a total sum. Finally, it writes this sum into cell B2. This process saves time by automating the addition and output steps.
