Excel Pivot Tables help summarize structured data without writing code. Use them to compare categories, aggregate measures, and explore a question while keeping the source records available.
1. Prepare a reliable source table
Give each column a single clear header, keep one record per row, and use consistent types for dates, numbers, and categories. Remove accidental blank header rows and check for inconsistent labels before building a PivotTable.
2. Arrange fields to answer a question
Place categories in Rows or Columns, numeric measures in Values, and optional filters in Filters. Check the value summary (such as Sum versus Count) and grouping so the result matches the question rather than the default layout.
3. Verify and communicate the result
Compare a sample total with the source data, refresh the PivotTable after source changes, and label the time period and measure. Use a PivotChart only when its visual form makes the comparison clearer.
Practice plan
Choose a small table with headers, create a summary by one category and one measure, verify one subtotal against the source, then add a second grouping and explain what changed.
