不用数组，用普通的函数提取

=LAMBDA(X,Y,MID(A1,X+1,Y-X-1))(FIND("/",A1),FIND("-",A1))

考虑全面一点的话=CONCAT(IFERROR(IF(FIND(MID(MID(A1,FIND("/",A1)+1,FIND("-",A1,FIND("/",A1))-FIND("/",A1)-1),ROW(INDIRECT("1:"&LEN(A1))),1),"0123456789."),MID(MID(A1,FIND("/",A1)+1,FIND("-",A1,FIND("/",A1))-FIND("/",A1)-1),ROW(INDIRECT("1:"&LEN(A1))),1)),""))*1
