Use Case: Highlight Overdue Tasks and Send Email Automatically

Let’s show you simple and practical use cases for both Excel VBA and Google Apps Script to demonstrate their unique capabilities. Consider you have a task tracker where you list everything about your tasks like Task, Start date, End Date, Status, Assigned To, team members Email addresses, etc.

Excel VBA

Excel VBA will highlight the due date and send an email alert when a task is overdue using Outlook.

• Go to the Developer tab >> select Visual Basic.
• In the VBA editor, go to Insert tab >> select Module.
• Insert the following VBA code in the Module.

VBA Code:

Sub SendOverdueTaskEmails()
    Dim ws As Worksheet
    Dim lastRow As Long
    Dim i As Long
    Dim OutlookApp As Object
    Dim OutlookMail As Object
    Dim taskName As String
    Dim endDate As Date
    Dim assignedTo As String
    Dim emailAddress As String
    Dim taskStatus As String
    Dim todayDate As Date
    
    ' Set worksheet and determine the last row
    Set ws = ThisWorkbook.Sheets("Tasks")
    lastRow = ws.Cells(ws.Rows.Count, 1).End(xlUp).Row
    todayDate = Date
    
    ' Initialize Outlook application
    On Error Resume Next
    Set OutlookApp = CreateObject("Outlook.Application")
    On Error GoTo 0
    
    If OutlookApp Is Nothing Then
        MsgBox "Outlook is not available. Please make sure Outlook is installed and configured.", vbCritical
        Exit Sub
    End If
    
    ' Loop through tasks in the dataset
    For i = 2 To lastRow
        taskName = ws.Cells(i, 2).Value
        endDate = ws.Cells(i, 4).Value
        assignedTo = ws.Cells(i, 5).Value
        taskStatus = ws.Cells(i, 6).Value
        emailAddress = ws.Cells(i, 7).Value
        
        ' Check if task is overdue and not completed
        If endDate < todayDate And taskStatus <> "Completed" Then
            ' Highlight the due date cell in red
            ws.Cells(i, 4).Interior.Color = RGB(255, 0, 0)
            
            ' Create the email
            Set OutlookMail = OutlookApp.CreateItem(0)
            With OutlookMail
                .To = emailAddress
                .Subject = "Overdue Task Notification: " & taskName
                .Body = "Dear " & assignedTo & "," & vbCrLf & vbCrLf & _
                        "The task """ & taskName & """ was due on " & endDate & " and is now overdue." & vbCrLf & _
                        "Please review and update the status as soon as possible." & vbCrLf & vbCrLf & _
                        "Best regards," & vbCrLf & _
                        "Task Management Team"
                .Send
            End With
            Set OutlookMail = Nothing
        End If
    Next i
    
    ' Clean up
    Set OutlookApp = Nothing   
    MsgBox "Emails sent for overdue tasks!", vbInformation
End Sub

Explanation:

• Set the Worksheet: The Tasks sheet is referenced, and the last row with data is determined.
• Initialize Outlook: Checks if Outlook is installed and sets up an Outlook application object.
• Loop Through Tasks:
  • Iterates through each task.
  • Retrieves details like task name, end date, assigned person, email, and status.
• Check Overdue Tasks: If the task is overdue (End Date < Today) and not marked “Completed,” the following actions occur:
  • Highlight in Red: The End Date cell is colored red (RGB(255, 0, 0)).
  • Send Email: Creates and sends an email using Outlook with task details.
• Cleanup: Releases the Outlook object and shows a confirmation message.

• Save and Run the code. Go back to your worksheet.

This code automates both task reminders via email and highlights overdue dates in Excel.

Output:

VBA Insights:

• Requires Microsoft Excel and Outlook installed on the same system.
• Reads task data from Excel, checks overdue tasks, highlights them in red, and sends emails via Outlook.
• It requires more setup, as you need to ensure proper configuration of Outlook and valid email addresses.
• Sensitive to runtime errors if email addresses or Outlook aren’t set up properly.

Google Apps Script

Using Google Apps Script send an email alert for overdue tasks using Gmail.

Steps:

• Go to the Extension menu >> select Apps Script.
• Insert the following script into the code editor.

Apps Script Code:

function sendOverdueTaskemail() {
  // Open the active sheet
  const sheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Tasks");
  
  // Get data range (assumes headers are in row 1)
  const range = sheet.getDataRange();
  const data = range.getValues();
  
  // Loop through rows starting from row 2
  for (let i = 1; i < data.length; i++) {
    const taskName = data[i][1]; // Task Name in column B
    const endDate = new Date(data[i][3]); // End Date in column D
    const assignedTo = data[i][4]; // Assigned To in column E
    const status = data[i][5]; //  Status in column F
    const email = data[i][6]; // Email Address in column G
    
    // Check if the task is overdue and not completed
    if (endDate < new Date() && status !== "Completed") 
      sheet.getRange(i + 1, 4).setBackground("red");
     {
      const subject = `Overdue Task Notification: ${taskName}`;
      const body = `Dear ${assignedTo},\n\nThe task "${taskName}" was due on ${endDate.toDateString()} and is now overdue. Please review and update the status as soon as possible.\n\nBest regards,\nTask Management Team`;
      
      // Send email
      GmailApp.sendEmail(email, subject, body);
    }
  }
  
  SpreadsheetApp.getUi().alert("Emails sent to the assigned individuals for overdue tasks!");
}

Explanation:

• Setup Sheet: Accesses the Tasks sheet and retrieves all data.
• Loop Through Tasks: Iterates through each row starting from the second.
• Check Overdue Tasks: If the End Date is past and the status isn’t “Completed”:
  • Highlights the End Date cell in red.
  • Send an email notification to the assigned person using Gmail.
• Completion: Displays a success message after processing.

Run the code and go back to your sheet to see the update. Check your mail account to see the email notifications.

Output:

Google Apps Script Insights:

• Runs directly in Google Sheets, using Gmail to send emails.
• Reads task data, highlights overdue tasks in red, and sends emails via Gmail.
• Simpler setup since Gmail is readily accessible in the Google ecosystem.
• No dependency on additional software like Outlook, making it lightweight.
