🛠️ Apps Script Code Snippets

Punch-In/Punch-Out Handler

function handlePunch(action) {
  const sheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Attendance");
  const timestamp = new Date();
  const user = Session.getActiveUser().getEmail();
  
  // Validate 4-digit password (stored in another sheet)
  const password = validatePassword(user); // Custom function
  
  if (password) {
    sheet.appendRow([user, action, timestamp]);
    return `Punch ${action} recorded at ${timestamp.toLocaleString()}`;
  }
  throw new Error("Invalid credentials.");
}

Automated Report Generator

function generateMonthlyReport() {
  const sheet = SpreadsheetApp.getActive().getSheetByName("Attendance");
  const data = sheet.getDataRange().getValues();
  const report = processData(data); // Custom logic for totals/overtime
  
  // Save to PDF and email to managers
  const pdf = createPDF(report);
  MailApp.sendEmail("manager@company.com", "Monthly Attendance Report", { attachments: [pdf] });
}
