This isn't a tutorial. It's real experience. Most articles about making money with Python are vague: "Learn Python to make money" (then what?) "Do data analysis freelancing" (how to get clients?) "Write web scrapers" (legal gray area) I'll share my actual path: building an Excel template generator with Python, listing it for sale, and earning my first dollar. Why This Direction My background: Know Python, but not expert Made some automation scripts No product design experience Want products (scalable) not services (time-for-money) The opportunity: Huge Excel template market (many 10k+ sales on Gumroad) Templates are static, hard to customize I can make a "template generator" for customization Technical feasibility: Python's openpyxl generates Excel programmatically JSON config is user-friendly ~300 lines of code The Product Not an Excel file. A Python script that generates Excel files . Users get: generator.py - generator code config.json - configuration README.md - documentation Workflow: Edit config.json → Run python generator.py → Get customized Excel Technical Implementation Core code is simple: from openpyxl import Workbook from openpyxl.styles import Font , PatternFill wb = Workbook () ws = wb . active # Header style header_fill = PatternFill ( start_color = ' 6366F1 ' , fill_type = ' solid ' ) header_font = Font ( bold = True , color = ' FFFFFF ' ) # Write header ws [ ' A1 ' ] = ' Project Name ' ws [ ' A1 ' ]. fill = header_fill ws [ ' A1 ' ]. font = header_font # Add dropdown from openpyxl.worksheet.datavalidation import DataValidation dv = DataValidation ( type = ' list ' , formula1 = '" In Progress,Completed,Paused "' ) ws . add_data_validation ( dv ) dv . add ( ' B2:B100 ' ) wb . save ( ' output.xlsx ' ) Loop to create sheets, set styles, add validation. Productization Process Step 1: MVP One module only (knowledge base) Test generation Use myself for a week Step 2: Expand Add 6 modules Add JavaScript version (using exceljs ) Improve docs Step 3: Package
