逗号分隔的列表成匹配的列配对

Question

我以为自己是个正派的床单骑师，但这是个强硬派。我只想使用公式将左侧变成右侧

也可以在https://docs.google.com/spreadsheets/d/1JgDZOV_K7SbOrCb27Z5K2XUBcrtq99GTCa3-BM2pOD0

进行采样

我找到的最接近的是这个（Separating Comma List into Cells with Formula），但它也没有匹配。

Answer 1

=ARRAYFORMULA(TRIM(SPLIT(TRANSPOSE(SPLIT(QUERY(TRANSPOSE(QUERY(TRANSPOSE(
 IF(IFERROR(SPLIT(B1:B, ","))<>"", "♠"&A1:A&"♦"&SPLIT(B1:B, ","), ))
 ,,999^99)),,999^99), "♠")), "♦")))

Answer 2

由@Matt:King替代：

=ARRAYFORMULA(QUERY(VLOOKUP(SEQUENCE(COUNTA(A2:A)*
 COLUMNS(SPLIT(B2:B, ",")), 1, 0)/ COLUMNS(SPLIT(B2:B, ","))+2,
 {ROW(A:A), A:A, TRIM(SPLIT(B:B, ","))}, MOD(SEQUENCE(COUNTA(A2:A)*
 COLUMNS(SPLIT(B2:B, ",")), 1, 0), COLUMNS(SPLIT(B2:B, ",")))*{0, 1}+{2, 3}),
 "where Col2 is not NULL"))
