如何从单元格中提取所有数字,例如A1单元格包含:" AA59"我想公式提取59并忽略AA。我可以使用= if(右(A1),2)公式,但如果A1包含值AA5,那么它将选择最后两个字符(即A5),所以这是错误的?
答案 0 :(得分:2)
这是一个原生工作表公式解决方案。与VBA用户定义函数相比,它有点不雅,但它是一个标准(非数组)公式,看起来比实际更复杂。
B21中的公式是,
=MID(A1, MIN(INDEX(ROW(INDIRECT("1:"&LEN(A1)))+((CODE(MID(A1,ROW(INDIRECT("1:"&LEN(A1))),1))<48)+(CODE(MID(UPPER(A1),ROW(INDIRECT("1:"&LEN(A1))),1))>57))*1E+99,,)), 99)
根据需要填写。将整个事物包裹在VALUE(...)
函数中,或者在MID
之前用双一元(又名双减或 - )将文本转换为真数。

作为替代方案,请考虑数组公式:
=--MID(SUMPRODUCT(--MID("01"&A1,SMALL((ROW($1:$300)-1)*ISNUMBER(-MID("01"&A1,ROW($1:$300),1)),ROW($1:$300))+1,1),10^(300-ROW($1:$300))),2,300)
从混合单元格中提取数字:
必须使用 Ctrl + Shift + 输入输入
数组公式,而不仅仅是 Enter key。

如果您总是尝试从字符串末尾获取单个或双位数字,请尝试以下版本:
=LOOKUP(100,RIGHT(A2,{1,2})+0)
