Frequently Asked Questions
How do I summarize sales?
Group by region, sum revenue, count orders: 10,000 rows collapse to a 12-row summary table. Aggregation choice changes answers — sum vs average deliberately.
Multiple groupings?
One group column per run — output is group, count, sum, avg. For two levels, pivot once, then pivot the result again.
Nulls in groups?
Missing keys bucket as (blank) — decide: exclude, impute, or investigate. Silent nulls skew summaries.
Do pivot tables upload?
No — pivoting runs locally in your browser. Data never leaves your device.
What numbers does the Default preset produce?
Grouped by role: Admin gives count 2, sum 157000.00, avg 78500.00 (75000+82000); Editor gives 1, 62000.00, 62000.00. Output headers are always group,count,sum,avg with 2-decimal sums; non-numeric values count as 0.
