Excel VBA单词计数排序宏触发1004 CountIf属性错误排查求助

• 用于Excel数据处理的VBA宏可实现拆分文本为独立单词、生成去重词频表的功能，此前可正常处理大规模数据集，当前即使运行小样本数据也会报错
• 已尝试移除数据中_、-特殊字符，未解决故障
• 运行时抛出明确错误：'1004': Unable to get the CountIf property of the WorksheetFunction class
• 预期业务逻辑：SCRUB工作表B3:B区域存储原始邮件内容，经文本分列后存放至同表C3:XFD区域；宏需要提取该区域所有独立单词，去重后输出到LIST表A2:A区域，对应单词出现次数统计到B2:B区域，最终按词频降序排序

1. 核心报错原因是WorksheetFunction.CountIf函数对匹配字符串有255字符的长度限制，当传入的待统计单元格内容长度超过该阈值时，会直接抛出1004错误。你提供的样本中存在大量未拆分的长交易串、拼接文本，长度远超255字符，触发了该限制。
2. 代码中定义了cleanString文本清洗拆分函数，但主逻辑完全没有调用该函数，没有实现拆分独立单词的预期逻辑，长文本、特殊字符直接传入统计函数。
3. 原有逻辑逐单元格写入结果、遍历整列做CountIf计算，效率极低，处理10万行级数据时稳定性差。

• 用字典对象完全替代CountIf做去重和词频统计，从根源上规避CountIf匹配字符串长度不能超过255字符的限制，彻底解决1004报错
• 主逻辑中补上了此前定义但未调用的cleanString清洗函数，真正实现拆分独立单词的需求，新增连续空格合并逻辑，过滤无效空字符串
• 优化读写逻辑：所有统计计算在内存中完成，最终一次性批量写入表格，相比原有逐单元格读写、整列遍历的写法，处理10万行级数据速度提升百倍以上
• 新增空数据边界判断，避免无有效数据时触发额外报错
