About Pivot Table Generator
A raw list of transactions or records — sales by region and product, survey responses by category — hides its own patterns until it's summarized: totals by group, counts by category, averages across a dimension. Building that summary by hand means manually grouping and adding up rows, or opening a full spreadsheet app just for one quick summary.
This tool takes CSV data and builds a real pivot table: pick which column becomes the row grouping, which becomes the column grouping, which numeric column gets aggregated, and how (sum, count, or average) — and see the summarized cross-tabulation instantly, with row and column totals calculated automatically.
This performs the actual pivot calculation, not just a preview — every cell shows the real aggregated value for that row-and-column combination, computed directly from your data, exportable as CSV to drop into a report or further analysis.
How it works
- Paste your CSV data. Include a header row identifying each column.
- Pick row, column, and value fields. Choose which columns to group by and which to aggregate.
- Choose an aggregation. Sum, count, or average — see the pivot table update instantly.
