A PRACTICAL GUIDE

How to use the Pivot Data Tool.

Pivoting needs a rule for repeated combinations. Do not discard duplicate values when the intended aggregation has not been specified.

Make the workflow fit your task.

Choose row identifiers, the field that becomes columns and the values to populate them. Check whether each row-and-column combination is unique. Set an aggregation rule only when repeated combinations genuinely need combining, then reconcile totals and missing cells.

Illustrative input and output · a teaching example, not a live WebAct run

Example input

Pivot month into columns. Each product/month pair is unique. CSV input:
product,month,value
A,Jan,10
A,Feb,12

Completed example

product,Jan,Feb
A,10,12

Check: both input observations remain represented; combined value stays 22. No aggregation was necessary.

Decisions and troubleshooting.

What should a pivot do when two values occupy the same output cell?

Apply an agreed aggregation or report the conflict. Selecting one value arbitrarily loses information.

Why did the pivot create a separate column for a nearly identical month?

Normalize inconsistent labels only after confirming they represent the same period, including year and date format.

Try it with your own source.

Replace the example with your material in the task prompt. Keep the requirements you need, then copy the task into WebAct.
