Google sheets 如何仅在超过一定数量的字符时删除单元格中的重复字

我需要删除单元格中的重复文本，但前提是该文本长度超过4个字符

我的公式只适用于任何类型的重复单词：

=join(" ",unique(transpose(split(A1,", "))))

在这种情况下，如果单元格包含：

W3-X500 Samsung Galaxy W3-X500 5 inches and 5 different colors

它返回给我：

W3-X500 Samsung Galaxy 5 inches and different colors

我将丢失所需的第二个

5

字符

---

我该怎么做呢？

我肯定有人会想出比这更简短的方法，但同时

=ArrayFormula(substitute(join(" ",unique(if(len(transpose(split(A1,", ")))<=4,
transpose(split(A1,", "))&rept("*",row(indirect("1:"&counta(split(A1,", "))))),transpose(split(A1,", "))))),"*",""))

=ArrayFormula（替换）（join（“），unique（if（len（transpose）（split（A1，”），unique））
=REGEXREPLACE（ArrayFormula）（join（“，”），
唯一（如果（LEN（（拆分为B1，“”）），
如果（LEN（（拆分（B1，“，”）））大于4，
（拆分（B1，“，”），
IF（LEN（（拆分（B1，“，”））
=ArrayFormula(substitute(join(" ",unique(transpose(if(len(split(A1,", "))<=4,
split(A1,", ")&rept("*",transpose(row(indirect("1:"&counta(split(A1,", ")))))),split(A1,", "))))),"*",""))

=ArrayFormula(substitute(join(" ",unique(transpose(split(A1,", "))&if(len(transpose(split(A1,", ")))<=4,
rept("*",row(indirect("1:"&counta(split(A1,", "))))),""))),"*",""))

=ArrayFormula(substitute(join(" ",unique(transpose(split(A1,", ")&if(len(split(A1,", "))<=4,
rept("*",transpose(row(indirect("1:"&counta(split(A1,", ")))))),"")))),"*",""))

=REGEXREPLACE(ARRAYFORMULA(JOIN(" ", 
 UNIQUE(IF(LEN((SPLIT(B1, ", "))), 
        IF(LEN((SPLIT(B1, ", ")))>4, 
               (SPLIT(B1, ", ")), 
        IF(LEN((SPLIT(B1, ", ")))<=4, 
               (SPLIT(B1, ", "))&
 "ᅇ"&CHAR(RANDBETWEEN(SIGN(ROW($A:$A))*1041, 1071))&
      CHAR(RANDBETWEEN(SIGN(ROW($A:$A))*1041, 1071))&
      CHAR(RANDBETWEEN(SIGN(ROW($A:$A))*1041, 1071))&"ᅇ", )), )))), 
 "\ᅇ([Б-Я]+)\ᅇ", "")
