I Built an Excel Robot - Now I Sleep 1 More Hour Every Day

2026-02-28

Hello everyone, this is programmer Wan Feng.

Let me start with a true story: I have a friend who works in finance. Every day before leaving work, she has to process a bunch of Excel reports.

Copy-paste, filter-sort, generate charts... At least 2 hours every day.

Last week she came to me complaining: "This work is so mechanical, I feel like a robot."

I said: "Then let a robot do it."

Three days later, her reports were fully automated. She now leaves on time every day.

What Work Can Be Automated?

Before rushing to learn technology, check if your work has these characteristics:

✅ High repetition —— Same tasks every week/month
✅ Clear rules —— Fixed processing logic
✅ Large data volume —— Time-consuming manual processing
✅ Error-prone —— Gets chaotic with more work, mistakes happen

If it matches 2 or more, strongly recommend automation.

Real Case: Sales Report Automation

My friend's requirements were:

Daily tasks:

Collect Excel files from 5 sales people
Merge into one master sheet
Summarize by product category
Generate bar charts and trend charts
Send email to boss

Before: 2 hours/day, often missing data
Now: 5 minutes setup, fully automated

How Is It Done? Super Simple

Using Python + AI, 30 lines of code:

import pandas as pd
import matplotlib.pyplot as plt
from email.mime.text import MIMEText

# 1. Automatically read all sales data
files = ['Sales1.xlsx', 'Sales2.xlsx', ...]
df = pd.concat([pd.read_excel(f) for f in files])

# 2. Summarize by product
summary = df.groupby('Product')['Sales'].sum()

# 3. Generate chart
summary.plot(kind='bar')
plt.savefig('TodaySales.png')

# 4. Send email (automatic)
send_email(to='boss@company.com', attachment='TodaySales.png')

That's it.

Even Better: Use AI to Write Code

If you can't understand the above, no problem.

Now there are AI tools where you can just speak human language:

Me: Help me write a program that automatically merges multiple Excel files,
    generates summary charts, then sends an email

AI: Sure, here's the complete code...
     (Auto-generates 30 lines of code)

Me: What if one file has the wrong format?

AI: Add exception handling...
     (Auto-modifies code)

You don't need to know programming, just need to describe your requirements.

Common Office Automation Scenarios

📊 Data Processing

Multiple table merge/split
Data cleaning (deduplication, formatting)
Auto-generate pivot tables
Batch rename files

📧 Message Notifications

Scheduled daily/weekly report sending
Monitor data anomalies and auto-alert
Mass personalized emails
WeChat/DingTalk group message push

🕐 Scheduled Tasks

Scheduled file backup
Scheduled competitor price scraping
Scheduled report generation
Scheduled expired data cleanup

🤖 Intelligent Processing

Auto-reply common questions
Auto-classify and organize documents
Auto-extract key information
Auto-generate summaries

What Do You Need to Learn?

Many people think automation is difficult, but actually there are only 3 core things:

1. Python Basics (1 week)

Variables, loops, conditions
File reading/writing
Excel processing (pandas library)
Sending requests (requests library)

2. Several Common Libraries (3 days)

openpyxl —— Excel operations
pandas —— Data analysis
smtplib —— Email sending
schedule —— Scheduled tasks

3. AI-Assisted Tips (Anytime)

How to describe requirements to AI
How to have AI modify code
How to debug and test

Total: 2 weeks to get started with simple automation.

What Can You Do After Learning?

Some real cases from students:

Case 1: Admin Lady

Before: Spent 1 hour daily organizing attendance sheets
Now: Program handles automatically, she focuses on employee care

Case 2: Operations Guy

Before: Manually collected data from 10 platforms
Now: Auto-scraping + generating visual reports

Case 3: Small Business Owner

Before: Hired part-time help costing 3000/month for order processing
Now: Automation system, cost reduced to 300/month

Time saved can be spent on more valuable things.
