Two main senses: (1) software/data —
导出 is the standard antonym of
导入 (dǎorù, "import") in apps and databases; (2) logic/math — to derive a result from premises or formulas, e.g.
导出公式 (derive a formula). Same character
导 (lead) but different mental models: "lead data out" vs "lead a conclusion out".
