将层级代码拆分为父项目（Google 工作表

Question

源单元格：CCA, BF 结果单元格：C, CC, CCA, B, BF

CCA 是与层次结构相关的复杂代码。这意味着，CCA 是 CC 的子项，CC 是 C 的子项。因此，该公式应拆分为所有父项（C 和 CC）并保留子项（CCA）——并对字符串的串联列表执行此操作。当前最大级别为四 (ABCD)，但将来可能会更多。

我不知道如何为此创建公式，但我得到了这个公式：=arrayformula( join( ", ", unique( flatten( transpose( left( split(A2, ", ", true, true), sequence( max( len( split(A2, ", ", true, true) ) ) ) ) ) ) ) ) )

参见 post here。

但是我需要一个数组公式，因为它可以应用于整个列

尝试：

=ARRAYFORMULA(REGEXREPLACE(FLATTEN(TRIM(QUERY(QUERY(QUERY({IFERROR(SPLIT(FLATTEN(
 IF(""=IFERROR(SPLIT(A1:A3, ", ")),,TEXT(ROW(A1:A3), "♥00000"))), "×")), 
 SEQUENCE(COLUMNS(SPLIT(A1:A3, ", "))*MAX(LEN(TRIM(SPLIT(QUERY(A1:A3&",",,9^9), ", "))))), 
 TRIM(FLATTEN(QUERY(IFERROR(REGEXREPLACE(SORT(TRANSPOSE(REGEXREPLACE(SPLIT(FLATTEN(
 IF(""=IFERROR(SPLIT(A1:A3, ", ")),,REPT(SPLIT(A1:A3, ", ")&"×", LEN(SPLIT(A1:A3, ", "))))), "×"), 
 {"(×)", "("&REPT(".", SEQUENCE(1, MAX(LEN(TRIM(SPLIT(QUERY(A1:A3&",",,9^9), ", "))))-1))&")$"}, )&","), 
 SEQUENCE(MAX(LEN(TRIM(SPLIT(QUERY(A1:A3&",",,9^9), ", "))))), 0), "^,$", )),,9^9)))}, 
 "select max(Col3) where Col1 is not null group by Col2 pivot Col1"), "offset 1", 0),,9^9))), ",$", ))

non-english 张：

=ARRAYFORMULA(REGEXREPLACE(FLATTEN(TRIM(QUERY(QUERY(QUERY({IFERROR(SPLIT(FLATTEN(
 IF(""=IFERROR(SPLIT(A1:A3; ", "));;TEXT(ROW(A1:A3); "♥00000"))); "×"))\ 
 SEQUENCE(COLUMNS(SPLIT(A1:A3; ", "))*MAX(LEN(TRIM(SPLIT(QUERY(A1:A3&",";;9^9); ", ")))))\ 
 TRIM(FLATTEN(QUERY(IFERROR(REGEXREPLACE(SORT(TRANSPOSE(REGEXREPLACE(SPLIT(FLATTEN(
 IF(""=IFERROR(SPLIT(A1:A3; ", "));;REPT(SPLIT(A1:A3; ", ")&"×"; LEN(SPLIT(A1:A3; ", "))))); "×"); 
 {"(×)"\ "("&REPT("."; SEQUENCE(1; MAX(LEN(TRIM(SPLIT(QUERY(A1:A3&",";;9^9); ", "))))-1))&")$"}; )&","); 
 SEQUENCE(MAX(LEN(TRIM(SPLIT(QUERY(A1:A3&",";;9^9); ", "))))); 0); "^,$"; ));;9^9)))}; 
 "select max(Col3) where Col1 is not null group by Col2 pivot Col1"); "offset 1"; 0);;9^9))); ",$"; ))

更新：

=ARRAYFORMULA(REGEXREPLACE(FLATTEN(TRIM(QUERY(QUERY(QUERY({IFERROR(SPLIT(FLATTEN(
 IF(""=IFERROR(SPLIT(A2:A; ", "));;TEXT(ROW(A2:A); "♥00000"))); "×"))\ 
 SEQUENCE(ROWS(IFERROR(SPLIT(FLATTEN(
 IF(""=IFERROR(SPLIT(A2:A; ", "));;TEXT(ROW(A2:A); "♥00000"))); "×"))))\ 
 TRIM(FLATTEN(QUERY(IFERROR(REGEXREPLACE(SORT(TRANSPOSE(REGEXREPLACE(SPLIT(FLATTEN(
 IF(""=IFERROR(SPLIT(A2:A; ", "));;REPT(SPLIT(A2:A; ", ")&"×"; LEN(SPLIT(A2:A; ", "))))); "×"); 
 {"(×)"\ "("&REPT("."; SEQUENCE(1; MAX(LEN(TRIM(SPLIT(QUERY(A2:A&",";;9^9); ", "))))-1))&")$"}; )&","); 
 SEQUENCE(MAX(LEN(TRIM(SPLIT(QUERY(A2:A&",";;9^9); ", "))))); 0); "^,$"; ));;9^9)))}; 
 "select max(Col3) where Col1 is not null group by Col2 pivot Col1"); "offset 1"; 0);;9^9))); ",$"; ))

但是如果你有大数据集，最好（更快）将它分成如下块：

=ARRAYFORMULA({REGEXREPLACE(FLATTEN(TRIM(QUERY(QUERY(QUERY({IFERROR(SPLIT(FLATTEN(
 IF(""=IFERROR(SPLIT(A2:A600; ", "));;TEXT(ROW(A2:A600); "♥00000"))); "×"))\ 
 SEQUENCE(ROWS(IFERROR(SPLIT(FLATTEN(
 IF(""=IFERROR(SPLIT(A2:A600; ", "));;TEXT(ROW(A2:A600); "♥00000"))); "×"))))\ 
 TRIM(FLATTEN(QUERY(IFERROR(REGEXREPLACE(SORT(TRANSPOSE(REGEXREPLACE(SPLIT(FLATTEN(
 IF(""=IFERROR(SPLIT(A2:A600; ", "));;REPT(SPLIT(A2:A600; ", ")&"×"; LEN(SPLIT(A2:A600; ", "))))); "×"); 
 {"(×)"\ "("&REPT("."; SEQUENCE(1; MAX(LEN(TRIM(SPLIT(QUERY(A2:A600&",";;9^9); ", "))))-1))&")$"}; )&","); 
 SEQUENCE(MAX(LEN(TRIM(SPLIT(QUERY(A2:A600&",";;9^9); ", "))))); 0); "^,$"; ));;9^9)))}; 
 "select max(Col3) where Col1 is not null group by Col2 pivot Col1"); "offset 1"; 0);;9^9))); ",$"; ); 
 REGEXREPLACE(FLATTEN(TRIM(QUERY(QUERY(QUERY({IFERROR(SPLIT(FLATTEN(
 IF(""=IFERROR(SPLIT(A601:A; ", "));;TEXT(ROW(A601:A); "♥00000"))); "×"))\ 
 SEQUENCE(ROWS(IFERROR(SPLIT(FLATTEN(
 IF(""=IFERROR(SPLIT(A601:A; ", "));;TEXT(ROW(A601:A); "♥00000"))); "×"))))\ 
 TRIM(FLATTEN(QUERY(IFERROR(REGEXREPLACE(SORT(TRANSPOSE(REGEXREPLACE(SPLIT(FLATTEN(
 IF(""=IFERROR(SPLIT(A601:A; ", "));;REPT(SPLIT(A601:A; ", ")&"×"; LEN(SPLIT(A601:A; ", "))))); "×"); 
 {"(×)"\ "("&REPT("."; SEQUENCE(1; MAX(LEN(TRIM(SPLIT(QUERY(A601:A&",";;9^9); ", "))))-1))&")$"}; )&","); 
 SEQUENCE(MAX(LEN(TRIM(SPLIT(QUERY(A601:A&",";;9^9); ", "))))); 0); "^,$"; ));;9^9)))}; 
 "select max(Col3) where Col1 is not null group by Col2 pivot Col1"); "offset 1"; 0);;9^9))); ",$"; )})
