ā” 1 AI Hack: Automate Variance Analysis in Excel (with ChatGPT)
š¬ Wait, ChatGPT Can Do Excel Work?
Yes ā and it's kind of magical. You donāt need macros, VBA, or 10 years of spreadsheet wizardry.
With a simple copy/paste, ChatGPT can analyze your Excel data, summarize key insights, and even suggest follow-up actions ā in seconds. Itās like having an intern who never sleeps (and never asks for coffee breaks).
š The Problem
You're reviewing a Budget vs Actuals report with 50+ line items. Your manager wants to know:
āWhat changed? Whatās worth paying attention to? And what should we do about it?ā
But you donāt have time to:
Manually calculate variance %
Color-code high-impact items
Write an insightful summary
Let AI handle the heavy lifting.
Hereās how to make your first automation happen:
š§° What Youāll Need:
Excel (or Google Sheets)
š This sample template (attached at the end)
ChatGPT (or Claude, Gemini, Copilot ā all work)

You are a senior financial analyst. Here's a budget vs actual report for Q1. For each line item, calculate the variance (Actual - Budget), the variance %, and flag any items with a variance greater than ±10%. Provide a short explanation of possible causes and suggest one follow-up action per item.
[Paste your table here]
Return the result in a table format I can paste directly into Excel.
4). Copy the AIās output back into Excel

Boom ā youāll get a clean, color-coded table with:
Variance math done
Explanations written
Suggested actions listed
ā Try It Yourself
Use your own data or try the demo template attached at the end.

šļø News Byte: The Fed Literally Makes Money šµš»
š§ Wait... the Fed just creates money?
Yep. And itās not some TikTok conspiracyāitās policy. Let's break it down š
š°ļø A (Very) Quick History of U.S. Central Banks etc.
1791 ā First Bank of the U.S. is born. Congress kills it after 20 years.
1816 ā Second Bank launches. Expired in 1836 after President Andrew Jackson shuts it down.
1836ā1913 ā No central bank for 77 years (yes, really).
1913 ā Enter: Federal Reserve, the third central bank. Created under the Federal Reserve Act to manage the U.S. money supply, support financial stability, and issue our currency when Democrats controlled both Houses of Congress and the Presidency
1913 - 16th Amendment was ratified which gives Congress power to lay and collect direct taxes from the people (quite contrary to Article 1, Sec 9 which prohibits direct taxes)
Fun fact: The 12 regional Fed banks are technically private corporations under federal oversight. Quirky.
šø How the Fed Actually Creates Money
Hereās the TL;DR:
Congress gave the Fed the power to create money from thin air. Literally.
It doesnāt print stacks of cash. It adds digits to reserve accounts of member banks such as JPMorganāa digital money printer.
When it buys bonds (like U.S. Treasuries or mortgage-backed securities), it wires digital dollars into member bank accounts through āopen market operationsā.
This increases reserves, lowers interest rates, and encourages lending (a.k.a. the money multiplier effect).
If things get too hot (i.e. inflation), the Fed reverses courseāselling assets to shrink the money supply.
š° How the Fed Earns Money (Yes, It Makes a Profit⦠Sort Of)
Here's the Fed's basic business model:
It creates money digitally from thin air, no backing šļøFiat
It uses that money to buy interest-bearing assets (like U.S. Treasuries).
It earns interest income on those assets.
The difference between what it earns and what it pays (operating expenses, pay dividends/interests to member banks on reserves held, and maintain capital buffer) is profit, which normally gets sent to the U.S. Treasury.
But lately? Not so profitable. With higher interest rates, the Fed is paying more out than itās earningāso itās running losses. No Treasury remittances until the books balance out again.
š QE Explained (No Jargon, Just Juice)
You hear this a lot in the news especially during economic crisis but what is it really?
Quantitative Easing (QE) = the Fed buying lots of bonds using newly created money.
Why?
To boost the economy when interest rate cuts arenāt cutting it.
How it works:
The Fed creates digital money š»šµ
Buys bonds from major banks & funds
Banks now have more cash (more reserves) = cheaper loans = more spending
Goal: fight recessions, keep markets moving, avoid deflation
QE = š for credit and spending.
ā ļø Money Supply vs Inflation...
QE boosts the money supply. But inflation takes off if:
People & businesses spend the new money fast
The economy canāt keep up producing goods/services
Supply is limited but demand skyrockets = š„ price increases
And remember: the U.S. dollar is fiat (not backed by gold or assets). So when too much money chases too few goods, the value of your dollars gets diluted. Value of money only increases when energy is expended i.e. increase in goods or services, NOT increase in money supply.

š„Why Itās Matters:
QE isnāt just monetary theory - it shapes your forecasts, asset valuations, and even expense assumptions.
Understanding how the Fed operates helps you anticipate market shifts (rates, inflation, lending conditions)
In a world of fiat currency and digital money, financial literacy = strategic advantage.
It affects your personal finance too, think hedging against high inflation, protect your future with hard or alternative assets (gold, silver or Bitcoin)
