How to Sum Cells Across Sheets in Google Sheets with AI (The Easy Way)

Let's be real - spreadsheets can feel like a maze sometimes. You've got data scattered across multiple tabs, and trying to sum it all up manually? That's a recipe for frustration. But here's the good news: AI is changing the game for spreadsheet users.

At Excelmatic, we've seen firsthand how AI can transform tedious spreadsheet tasks into simple, one-click operations. Today, I'll show you how to sum cells across different Google Sheets tabs - both the traditional way and the smarter AI-powered approach.

Why Summing Across Sheets Matters

Imagine you're tracking monthly sales across different regions. Each region has its own tab, but you need a master summary. This is where cross-sheet summing becomes essential. Without it, you're stuck copying and pasting data or writing complex formulas that break when you add new tabs.

The Manual Method (For Reference)

First, let's cover the basic formula approach:

  1. In your summary sheet, click where you want the total
  2. Type =SUM(
  3. Click your first sheet tab and select the cell range
  4. Add a comma, then repeat for other sheets
  5. Close with ) and press Enter

The formula looks like: =SUM(North!B2:B10, South!B2:B10)

While this works, it's clunky. Add more regions? You'll need to update the formula. Have dozens of tabs? Good luck keeping track.
