Filling it in

Use YYYY-MM-DD for every date. Mixed formats break period comparisons.
Numeric columns may contain thousands separators, but no currency symbols or text.
Rows missing a required column are excluded. Zero and blank are treated differently.
Extra columns are fine—anything this tool does not use is ignored.
