Excel Generation Workflow

1. Data Preparation

   import pandas as pd
   import xlsxwriter
   from datetime import datetime
   
   # Load and prepare data
   df_crawls = pd.read_sql(crawl_query, connection)
   df_metrics = pd.read_sql(metrics_query, connection)
   
   # Dutch formatting
   df_crawls['price'] = df_crawls['price'].apply(
       lambda x: f"€ {x:,.2f}".replace(',', 'X').replace('.', ',').replace('X', '.')
   )

2. Workbook Creation

   # Create Excel writer with xlsxwriter engine
   writer = pd.ExcelWriter('seo_report.xlsx', engine='xlsxwriter')
   workbook = writer.book
   
   # Define formats
   formats = {
       'header': workbook.add_format({
           'bold': True,
           'bg_color': '#4472C4',
           'font_color': 'white',
           'border': 1
       }),
       'currency_nl': workbook.add_format({
           'num_format': '€ #,##0.00'
       }),
       'percentage': workbook.add_format({
           'num_format': '0.0%'
       })
   }
