🚀 Step 1: Excel Automation = Data Team Killer (Run this!)

## !pip install openpyxl pandas  # Run once!

import pandas as pd
from openpyxl import Workbook
from openpyxl.styles import Font, PatternFill, Alignment
from openpyxl.chart import BarChart, Reference

## REAL BUSINESS DATA
months = ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun']
sales = [25000, 32000, 28000, 45000, 52000, 61000]
profits = [6250, 8960, 6160, 14400, 18200, 23180]

## CREATE EXECUTIVE EXCEL
wb = Workbook()
ws = wb.active
ws.title = "Executive Summary"

## ADD DATA + FORMATTING
headers = ['Month', 'Sales', 'Profit']
for col, header in enumerate(headers, 1):
    ws.cell(row=1, column=col, value=header).font = Font(bold=True, color="FFFFFF")
    ws.cell(row=1, column=col).fill = PatternFill("solid", fgColor="2E86AB")

## DATA ROWS
for row, (month, sale, profit) in enumerate(zip(months, sales, profits), 2):
    ws[f'A{row}'] = month
    ws[f'B{row}'] = sale
    ws[f'C{row}'] = profit
    for col in ['B', 'C']:
        ws[f'{col}{row}'].number_format = '$#,##0'

## AUTO CHART
chart = BarChart()
chart.type = "col"
chart.style = 10
chart.title = "Monthly Performance"
chart.y_axis.title = 'Amount ($)'
data = Reference(ws, min_col=2, min_row=1, max_row=7, max_col=3)
cats = Reference(ws, min_col=1, min_row=2, max_row=7)
chart.add_data(data, titles_from_data=True)
chart.set_categories(cats)
ws.add_chart(chart, "E2")

wb.save("🚀 Executive_Summary.xlsx")
print("✅ EXECUTIVE EXCEL CREATED!")
print("📊 Auto-formatted + chart included!")

🔥 Step 2: PowerPoint Automation = C-Suite Ready

## !pip install python-pptx  # Run once!

from pptx import Presentation
from pptx.util import Inches, Pt
from pptx.dml.color import RGBColor
from pptx.enum.text import PP_ALIGN

## CREATE EXECUTIVE PRESENTATION
prs = Presentation()

## SLIDE 1: TITLE
slide_layout = prs.slide_layouts[0]
slide = prs.slides.add_slide(slide_layout)
title = slide.shapes.title
title.text = "🚀 Monthly Business Review"
title.text_frame.paragraphs[0].font.size = Pt(44)
title.text_frame.paragraphs[0].font.color.rgb = RGBColor(46, 134, 171)

## SLIDE 2: KPI DASHBOARD
slide_layout = prs.slide_layouts[1]
slide = prs.slides.add_slide(slide_layout)
title = slide.shapes.title
title.text = "📊 Key Metrics"

content = slide.placeholders[1]
tf = content.text_frame
tf.text = "Total Sales: $243,000\nTotal Profit: $78,150\nGrowth MoM: +18.5%\nTop Product: Laptop"
for paragraph in tf.paragraphs:
    paragraph.font.size = Pt(24)
    paragraph.font.color.rgb = RGBColor(162, 59, 114)
    paragraph.alignment = PP_ALIGN.CENTER

## SLIDE 3: CHARTS
slide_layout = prs.slide_layouts[5]
slide = prs.slides.add_slide(slide_layout)
title = slide.shapes.title
title.text = "📈 Performance Charts"

content = slide.placeholders[1]
tf = content.text_frame
tf.text = "• Sales up 22% YoY\n• Profit margin: 32.1%\n• 3 consecutive record months\n• Laptop = 45% revenue"
for paragraph in tf.paragraphs:
    paragraph.font.size = Pt(20)
    paragraph.font.color.rgb = RGBColor(241, 143, 1)

prs.save("🎯 Executive_Presentation.pptx")
print("✅ EXECUTIVE POWERPOINT CREATED!")
print("📊 3 professional slides ready!")

Step 3: PDF Reports = Professional Polish

## !pip install reportlab  # Run once!

from reportlab.lib.pagesizes import letter, A4
from reportlab.platypus import SimpleDocTemplate, Paragraph, Spacer, Table, TableStyle
from reportlab.lib.styles import getSampleStyleSheet, ParagraphStyle
from reportlab.lib import colors
from reportlab.lib.units import inch

## CREATE PROFESSIONAL PDF
doc = SimpleDocTemplate("📋 Executive_Report.pdf", pagesize=A4)
styles = getSampleStyleSheet()

## CUSTOM EXECUTIVE STYLE
executive_style = ParagraphStyle(
    'Executive',
    parent=styles['Heading1'],
    fontSize=24,
    spaceAfter=30,
    textColor=colors.HexColor('#2E86AB'),
    alignment=1  # Center
)

story = []

## TITLE
story.append(Paragraph("🚀 Monthly Executive Summary", executive_style))
story.append(Spacer(1, 0.3*inch))

## KPI TABLE
kpi_data = [
    ['Metric', 'Value', 'vs Last Month'],
    ['Total Sales', '$243,000', '+18.5%'],
    ['Total Profit', '$78,150', '+24.2%'],
    ['Avg Margin', '32.1%', '+2.1%'],
    ['Top Product', 'Laptop (45%)', 'Unchanged']
]

table = Table(kpi_data)
table.setStyle(TableStyle([
    ('BACKGROUND', (0, 0), (-1, 0), colors.HexColor('#2E86AB')),
    ('TEXTCOLOR', (0, 0), (-1, 0), colors.whitesmoke),
    ('ALIGN', (0, 0), (-1, -1), 'CENTER'),
    ('FONTNAME', (0, 0), (-1, 0), 'Helvetica-Bold'),
    ('FONTSIZE', (0, 0), (-1, 0), 14),
    ('BOTTOMPADDING', (0, 0), (-1, 0), 12),
    ('BACKGROUND', (0, 1), (-1, -1), colors.beige),
    ('GRID', (0, 0), (-1, -1), 1, colors.black)
]))
story.append(table)

doc.build(story)
print("✅ PROFESSIONAL PDF CREATED!")
print("📊 Executive-ready with tables!")

🧠 Step 4: FULL AUTOMATION PIPELINE (Production!)

    start_time = time.time()

    print("🤖 WEEKLY REPORT AUTOMATION STARTING...")

    # STEP 1: Generate data insights
    total_sales = sum(sales)
    total_profit = sum(profits)
    growth_rate = ((sales[-1] - sales[0]) / sales[0]) * 100

    # STEP 2: Excel
    print("📊 Creating Excel...")
    # [Excel code from Step 1]

    # STEP 3: PowerPoint
    print("🎯 Creating PowerPoint...")
    # [PPT code from Step 2]

    # STEP 4: PDF
    print("📋 Creating PDF...")
    # [PDF code from Step 3]

    end_time = time.time()

    print(f"\n✅ AUTOMATION COMPLETE!")
