Excel or Flask First: What Beginners Should Pick

SECTION 01What is Excel?

Excel is Microsoft's spreadsheet software. It is used to organize, analyze, and visualize data. It's the foundation of most business analysis roles.

You use it to build financial models, pivot tables, and charts. It's not used to build web apps. It's used to understand data.

=VLOOKUP(A2, Sheet2!B:C, 2, FALSE)
=SUMIFS(B:B, C:C, ">=2026-01-01", D:D, "Active")
=PIVOTBY(...)

SECTION 02What is Flask?

Flask is a lightweight Python web framework. It's used to build web applications, REST APIs, and backend services.

You write it in Python. It's not a data analysis tool. It's a tool for building the web.

from flask import Flask
app = Flask(__name__)

@app.route('/')
def hello():
    return "Hello, World!"
