How to use CSV Pivot Table

Summarize categorical records without executing SQL or spreadsheet formulas. Missing numeric values are rejected rather than silently treated as zero.

  1. Enter input, row-key column, pivot-key column, value column.
  2. Choose the settings for csv pivot table, then run the tool.
  3. Review the result and any limitations before copying or downloading it.

Good to know

  • Blank or colliding pivot categories receive deterministic nonblank unique headers; the visible mapping preserves the original category text.
  • 5,000 CSV records, 100 pivot categories and 10,000 output cells. Count includes every record; absent groups produce empty cells.
  • Sum/mean use floating-point arithmetic rounded to 12 significant digits, not exact finance arithmetic. CSV downloads protect formula-like cells.
  • Processing is local. Output is limited to 1,000,000 text characters unless a stricter file limit is stated.

Common questions

Is a pivot the same as transposing?

No. It groups and aggregates records; transposition merely swaps physical rows and columns.

Is this input sent to a server?

No. The application processes this input inside your browser tab and does not save it to persistent storage.
