Why You Should Delete Your SUMIF Formulas (The GROUPBY Revolution)

Stop Using SUMIF: The Dynamic Future of Excel Reports

Are you still writing separate formulas for every category? You might be living in the past, and it’s costing you time and accuracy.

The Problem: The "Amateur Hour" of SUMIF

Using SUMIF for manual reporting is "amateur hour." If you find yourself writing a separate formula for every single category, your workflow is static and dangerous.

The Human Error Trap: When a new region or category appears in your data, a static report misses it entirely. You are forced into manual updates, formula increments, and verifying cell references every single time the data changes.

The Solution: The Power of =GROUPBY

Instead of manual labor, use the new GROUPBY function. It creates a fully dynamic summary table with just one single formula. No drag-and-drop, and no bulky Pivot Tables required.

Pro Tip: When new data arrives, the GROUPBY summary expands automatically to include new categories and updated totals.

How to Implement It

The GROUPBY function requires three primary arguments to work its magic:

=GROUPBY(row_fields, values, function)

// Example from the video:
=GROUPBY(Data[Region], Data[Sales], SUM)

1. Select your Categories: Point to the column containing your regions or groups.
2. Select your Numbers: Point to the sales or data column.
3. Choose your Math: Use SUM, AVERAGE, COUNT, or others.
