比较单元格中逗号分隔的字母数字值

Question

我与以下主题中提到的场景相同 Comparing comma separated numbers in cells 但是我有数字表，而不是数字，我需要查找不匹配的值。参见下图。

我使用了罗恩·罗森菲尔德（Ron Rosenfeld）给出的以下公式，但无法将其用于字母数字数据。

=TEXTJOIN(",",TRUE,IFERROR(1/(1/(ISNUMBER(FIND(","&TRIM(MID(SUBSTITUTE(B2,",",REPT(" ",99)),seq_99,99))&",",","&A2&","))))*TRIM(MID(SUBSTITUTE(B2,",",REPT(" ",99)),seq_99,99)),""))

seq_99指

=IF(ROW(INDEX($1:$65535,1,1):INDEX($1:$65535,255,1))=1,1,(ROW(INDEX($1:$65535,1,1):INDEX($1:$65535,255,1))-1)*99)

谢谢！
