Extract only the current-period (2015) column; never use the 2014 prior-year column. lineItem is the Dutch label exactly as printed. For grouped balans entries with indented sub-amounts plus a rolled-up subtotal, take the outer (rightmost) roll-up figure for the group label and the inner figures for the indented detail lines. For the income statement, detail lines use the inner money column and subtotal/result lines use the outer roll-up column; keep negatives negative. Include only lines that carry a monetary amount; skip pure section headers. Amounts are numbers in EUR without thousands separators.
