## When to use

- When you need to derive new metrics from multiple columns in a CSV or table.
- When you want to quickly summarize row-level data like sums, averages, or ranges.
- When you need to format raw data into structured formats like JSON, HTML, or Markdown tables.

## How it works

- Paste your CSV or table data into the input field and specify the delimiter if necessary.
- Select the mathematical operation you wish to perform, such as Sum, Average, or Product.
- Define the specific columns to include in the calculation and provide a name for the new result column.
- Choose your preferred output format and click calculate to generate the updated table.

## Use cases

- Calculating total sales revenue by summing individual item prices across rows.
- Determining the average performance score for students or employees from multiple test columns.
- Finding the range or variance between different data points in a financial dataset.
