Excel-从文本中提取所有日期

Question

假设我有以下情况：

Today's Date is 08/20/2020 and tomorrow's date is 30/10/2018. Status = N/A
Yesterday's Date status is stuff/things but it  is 2020/08/31 and today is 8/20/18.

我要退货的是

08/20/2020, 30/10/2018
2020/08/31, 08/20/18

关于如何执行此操作的任何建议？

Answer 1

在数组公式中使用TEXTJOIN：

=SUBSTITUTE(TEXTJOIN(", ",TRUE,IF(ISNUMBER(SEARCH("*/*/*",TRIM(MID(SUBSTITUTE(A1," ",REPT(" ",99)),(ROW($1:$25)-1)*99+1,99)))),TRIM(MID(SUBSTITUTE(A1," ",REPT(" ",99)),(ROW($1:$25)-1)*99+1,99)),"")),".","")

作为数组公式，退出编辑模式时需要使用Ctrl-Shift-Enter而不是Enter进行确认。

TEXTJOIN是Office 365 Excel引入的

如果您没有Office 365，则每个“日期”的输出必须位于不同的单元格中。

将其放在B1中，上下复制：

=IFERROR(SUBSTITUTE(TRIM(MID(SUBSTITUTE($A1," ",REPT(" ",99)),(AGGREGATE(15,6,ROW($1:$25)/(ISNUMBER(SEARCH("*/*/*",TRIM(MID(SUBSTITUTE($A1," ",REPT(" ",99)),(ROW($1:$25)-1)*99+1,99))))),COLUMN(A:A))-1)*99+1,99)),".",""),"")
