How to create pivot tables from excel data entirely in your browser
- Step 1Upload flat data file — Drop your flat XLSX or CSV file (one row per observation) onto the Pivot Generator.
- Step 2Configure pivot fields — Select row field (e.g. Region), column field (e.g. Quarter), value field (e.g. Revenue), and aggregation (SUM).
- Step 3Generate pivot table — The tool builds the cross-tabulation and calculates grand totals.
- Step 4Download XLSX — Save the pivot output as an Excel file for further analysis or presentation.
Frequently asked questions
Does the output include grand totals?+
Yes — a Grand Total row is appended to the bottom of the pivot table. A Grand Total column is included when using SUM aggregation.
Can I have multiple value fields?+
Run the pivot generator once per value field and combine the outputs manually. Multi-value-field pivots are on the roadmap.
