Excel COUNTIF公式日期格式修正：统计2023年1月日期单元格数量

To fix the code and convert column A to date format, you can use the DATEVALUE function. Here's the modified code: =COUNTIF(A1:A11,""&TEXT(DATEVALUE("2023/01/01"),"yyyy/mm")&"/") This code will count the number of cells in column A that contain a date in the format "2023/01/XX", where XX can be any day within the month.
