Frequently asked questions
Is my CSV data uploaded to a server?
No — all pivot processing happens locally in your browser using JavaScript. Your data never leaves your device.
What aggregation functions are supported?
Sum, Count, Average (Mean), Min, and Max are supported. Each cell in the pivot table shows the aggregated value for that row/column combination.
Is a Column field required?
No — the Column field is optional. If you omit it, the pivot table shows a single "Total" column with the aggregated value per row.
Can I pivot on text values?
The Value field should be numeric for Sum, Average, Min, and Max. Count works with any column type.
How many rows can it handle?
The pivot logic runs in-browser and handles tens of thousands of rows without issues. Very large files may be slow on older devices.
Can I download the pivot result?
Yes — click Download CSV after generating the pivot table to save the result as a CSV file.
