推荐答案

错误信息非常清楚.您尝试添加到验证列表的某些值超过 Excel 允许的最大长度 255 个字符.要么缩短值，要么尝试此建议使用隐藏范围来解决限制.

The error message is pretty clear. Some of the values you are trying to add to the validation list are longer than the maximum length allowed by Excel, 255 characters. Either shorten the values or maybe try this suggestion of using hidden ranges to work around the limitation.
