Proof That Non-Developers Can Automate
Every day, I was exhausted by repetitive Excel work. Data sorting, format conversion, duplicate removal, all done manually.
Then I discovered Claude Code.
Step 1: Identify Your Problem Clearly
The first rule of automation is: "What exactly repeats?"
💡 **My Checklist**
- What's the repeating task? → Organizing order data
- How long does it take? → About 2 hours
- Error rate? → Around 15%
Step 2: Use Claude Code
Stage 1: Write Your Request
"Every month 30th, I get a CSV file.
I need to remove duplicates,
sort by date,
and save as an Excel file."
Key: No technical jargon needed, just describe what you do.
Stage 2: Claude Code Generates Code
Claude Code creates a Python script you run on your Windows device.
# Sample code Claude Code generates
import pandas as pd
df = pd.read_csv('input.csv')
df_clean = df.drop_duplicates()
df_sorted = df_clean.sort_values('date')
df_sorted.to_excel('output.xlsx', index=False)
Stage 3: Test Small First
• Test with a **10-row sample file** first
• If it works, apply to real data
• If it fails, ask Claude Code to refine
Results: Victory
Once set up, I scheduled the script to run automatically each month.
Before & After:
• ⏱️ Time: 2 hours → 5 minutes
• 🎯 Accuracy: 85% → 99.8%
• 😊 Peace of mind: Priceless
Final Tip: Embrace Imperfection
Your first attempt doesn't need to be perfect. Working with Claude Code is an iterative process.
Just say: "This didn't work. Can you adjust it?" Claude Code rebuilds the code instantly.
