What is a pivot table?
A pivot table is a data summarization tool that automatically sorts, counts, totals, or averages data stored in one table or spreadsheet. It helps you:

Pivot tables are essential for business intelligence, financial analysis, sales reporting, and data exploration.
How do I create a pivot table?
Creating a pivot table is simple:
1. Input Data: Paste CSV or JSON data, or upload a file
2. Choose Row Fields: Select which fields to use as rows (e.g., Region, Product)
3. Choose Column Fields (Optional): Select fields for columns (e.g., Year, Quarter)
4. Choose Value Fields: Select numeric fields to aggregate (e.g., Sales, Quantity)

The tool automatically calculates totals and grand totals for your analysis.
What aggregation functions are available?
The tool supports five aggregation functions:
- Sum: Add up all values (useful for sales, revenue, quantities)
- Count: Count number of records (useful for transactions, occurrences)
- Average: Calculate mean value (useful for ratings, prices)
- Minimum: Find lowest value (useful for prices, scores)
- Maximum: Find highest value (useful for peaks, limits)

Does my data leave my device?
No. All pivot table creation and calculation happens entirely in your browser using JavaScript. Your data never leaves your machine, ensuring complete privacy for sensitive business data, financial reports, or customer information.
What data formats are supported?
The tool accepts two common data formats:
1. CSV: Comma-separated values with headers in first row
Example:
Region,Product,Sales
North,Widget,100
South,Widget,150
2. JSON: Array of objects
Example:
[{"Region": "North", "Product": "Widget", "Sales": 100}]
You can also use Auto-detect to let the tool determine the format automatically.
Can I export the pivot table?
Yes. After creating a pivot table, you can:
- Download as CSV: Export the summarized data for use in Excel or Google Sheets
- Download as JSON: Export for use in applications or further analysis
- Copy to clipboard: Copy the table to paste into documents or spreadsheets
All exports preserve the calculated totals and structure of your pivot table.
