USE CASES

When to use Summarize a CSV?

Prepare and review a one-axis summary: profile columns, anticipate groups, count rows or calculate sum, average, minimum or maximum for a numeric measure.

Get headcount by department without Excel formulas
Calculate total or average amount by category while seeing ignored values
Review and sort groups before downloading the summary

CONCRETE EXAMPLE

Amounts by department

BEFORE

1,800 rows · department + amount · a few blank/text amounts

→

AFTER

Column/group preflight · non-numeric values flagged · reviewed summary · CSV export

GOOD TO KNOW

Limitations to know

The summary uses one grouping axis; use the pivot tool to cross rows and columns.
Blank or non-numeric values are ignored for numeric aggregation while their rows remain counted in the group.
Groups are distinguished by exact text after trimming edge spaces; business variants are not automatically merged.

HOW IT WORKS

1Prepare the required input and choose useful options.
