Complete walkthrough for Mail Merge, Excel Functions, VBA, and Data Analysis

1. Mail Merge Implementation

1.1 HTML/JavaScript Mail Merge

1
Create your template

Design your email template with placeholders in double curly braces like {{FirstName}}:

2
Prepare your CSV data

Create a comma-separated list of data with headers in the first row:

3
Run the mail merge

Click the button to generate personalized emails for each record:

Output:

Note: This implementation handles basic mail merge needs. For advanced features like attachments or HTML formatting, consider server-side solutions.

1.2 Excel VBA Mail Merge

1
Set up your Excel workbook

Create two sheets:

  • Data: Contains your records (headers in row 1)
  • Template: Contains your email template with placeholders
2
Press Alt+F11 to open the VBA editor

Insert a new module and paste this code:

Sub PerformMailMerge()
    Dim wsData As Worksheet, wsTemplate As Worksheet
    Dim rngData As Range, lastRow As Long, i As Integer
    
    ' Set worksheet references
    Set wsData = ThisWorkbook.Sheets("Data")
    Set wsTemplate = ThisWorkbook.Sheets("Template")
    
    ' Find last row of data
    lastRow = wsData.Cells(wsData.Rows.Count, "A").End(xlUp).Row
    
    ' Set data range (headers in row 1)
    Set rngData = wsData.Range("A2:D" & lastRow)
    
    ' Clear previous output
    wsTemplate.Range("Output").ClearContents
    
    ' Loop through records
    For i = 1 To rngData.Rows.Count
        Dim mergedText As String
        mergedText = wsTemplate.Range("TemplateText").Value
        
        ' Replace placeholders with actual values
        mergedText = Replace(mergedText, "{{Name}}", rngData.Cells(i, 1).Value)
        mergedText = Replace(mergedText, "{{Product}}", rngData.Cells(i, 2).Value)
        mergedText = Replace(mergedText, "{{Amount}}", Format(rngData.Cells(i, 3).Value, "$#,##0.00"))
        mergedText = Replace(mergedText, "{{Date}}", Format(rngData.Cells(i, 4).Value, "mmmm d, yyyy"))
        
        ' Output merged text
        wsTemplate.Range("Output").Offset(i - 1, 0).Value = mergedText
    Next i
    
    MsgBox "Mail merge completed for " & rngData.Rows.Count & " records.", vbInformation
End Sub
3
Run the macro

Press F5 to execute the code. The merged emails will appear in your Template sheet.

Important: Always enable macros only from trusted sources. Save your file as .xlsm to preserve the macro.

2. Essential Excel Functions

2.1 VLOOKUP Function

1
Understand the syntax
=VLOOKUP(lookup_value, table_array, col_index_num, [range_lookup])
  • lookup_value: Value to search for
  • table_array: Range containing the data
  • col_index_num: Column number to return (starting from 1)
  • range_lookup: FALSE for exact match, TRUE for approximate match
2
Create sample data
EmployeeIDNameDepartmentSalary
101John SmithMarketing$5,200
102Jane DoeSales$6,500
103Bob JohnsonIT$7,800
3
Write the formula

To find the department for employee ID 102:

=VLOOKUP(102, A2:D4, 3, FALSE)

This will return "Sales"

To find the salary for "Bob Johnson":

=VLOOKUP("Bob Johnson", B2:D4, 3, FALSE)

This will return "$7,800"

Limitation: VLOOKUP can only search the leftmost column of your table_array and can't look to the left.

2.2 INDEX and MATCH (Better alternative)

1
Understand the syntax
=INDEX(return_range, MATCH(lookup_value, lookup_range, match_type))

MATCH finds the position, INDEX returns the value at that position.

2
Using the same data

To find the department for employee ID 102:

=INDEX(C2:C4, MATCH(102, A2:A4, 0))

Returns "Sales"

To find EmployeeID for "Bob Johnson":

=INDEX(A2:A4, MATCH("Bob Johnson", B2:B4, 0))

Returns 103

Advantage: INDEX/MATCH can look in any direction and is more flexible than VLOOKUP.

3. VBA & Macros

3.1 Creating Your First Macro

1
Enable Developer Tab

Go to File > Options > Customize Ribbon > Check "Developer" > OK

2
Record a macro

On the Developer tab, click "Record Macro". Perform some actions (like formatting cells), then stop recording.

3
View the code

Press Alt+F11 to open the VBA editor. You'll see the generated code in Module1.

3.2 Writing a Useful Macro

1
Create a formatting macro

Insert this code to automatically format a sales report:

Sub FormatSalesReport()
    ' Turn off screen updating for better performance
    Application.ScreenUpdating = False
    
    With ActiveSheet
        ' Autofit all columns
        .Columns.AutoFit
        
        ' Format headers
        With .Range("A1:G1")
            .Font.Bold = True
            .Interior.Color = RGB(200, 230, 255)  ' Light blue
            .Borders(xlEdgeBottom).LineStyle = xlContinuous
        End With
        
        ' Format currency columns
        .Range("F2:F100").NumberFormat = "$#,##0.00"
        
        ' Add alternating row colors
        With .Range("A2:G100")
            .FormatConditions.Add Type:=xlExpression, Formula1:="=MOD(ROW(),2)=0"
            .FormatConditions(1).Interior.Color = RGB(240, 240, 240)
        End With
    End With
    
    ' Turn screen updating back on
    Application.ScreenUpdating = True
    
    MsgBox "Report formatted successfully!", vbInformation
End Sub
2
Assign to a button

On the Developer tab, insert a button and assign this macro to it for one-click formatting.

4. Data Analysis Techniques

4.1 SUBTOTAL Function

1
Understand the syntax
=SUBTOTAL(function_num, range1, [range2], ...)

Common function numbers: 1=AVERAGE, 2=COUNT, 9=SUM, 11=VAR

2
Create sample data
RegionSales
East$1,000
East$1,500
West$2,000
West$1,800
3
Calculate subtotals

For East region total:

=SUBTOTAL(9, B2:B3)

Returns $2,500

For West region average:

=SUBTOTAL(1, B4:B5)

Returns $1,900

4.2 Pivot Tables

1
Prepare your data

Ensure your data has:

  • No blank rows or columns
  • Clear headers in the first row
  • Consistent data in each column
2
Create the pivot table

Select your data > Insert > PivotTable > Choose location

3
Configure fields

Drag fields to these areas:

  • Rows: Categories to group by (e.g., Region)
  • Columns: Secondary categories (e.g., Quarter)
  • Values: Numbers to calculate (e.g., Sum of Sales)
  • Filters: Optional filters
4
VBA code to create pivot table
Sub CreatePivotAutomatically()
    Dim wsData As Worksheet, wsPivot As Worksheet
    Dim pc As PivotCache, pt As PivotTable
    Dim rngData As Range, lastRow As Long
    
    ' Set references
    Set wsData = ThisWorkbook.Sheets("SalesData")
    Set wsPivot = ThisWorkbook.Sheets.Add
    wsPivot.Name = "PivotAnalysis"
    
    ' Find last row dynamically
    lastRow = wsData.Cells(wsData.Rows.Count, "A").End(xlUp).Row
    Set rngData = wsData.Range("A1:G" & lastRow)
    
    ' Create pivot cache and table
    Set pc = ThisWorkbook.PivotCaches.Create(SourceType:=xlDatabase, SourceData:=rngData)
    Set pt = pc.CreatePivotTable(TableDestination:=wsPivot.Range("B3"), TableName:="SalesPivot")
    
    ' Configure fields
    With pt
        ' Add row and column fields
        .AddFields RowFields:="Region", ColumnFields:="Quarter"
        
        ' Add data field
        .AddDataField .PivotFields("Sales"), "Sum of Sales", xlSum
        
        ' Format numbers
        .DataBodyRange.NumberFormat = "$#,##0"
        
        ' Apply style
        .TableStyle2 = "PivotStyleMedium9"
    End With
    
    MsgBox "Pivot table created successfully!", vbInformation
End Sub
