Group and aggregate CSV rows

Group by up to three columns and calculate counts, sums, averages, minimums, or maximums.

How it works

  1. Choose a CSV and review category and numeric columns.
  2. Set up to three group columns and the aggregations.
  3. Run, review group and row counts, and download.

Before you start

  • Sums and averages use JavaScript Number, not exact financial decimal arithmetic.
  • Blanks are ignored and averages use the numeric count. All-blank groups stay blank; invalid numbers stop processing.
