As for the POI3 version, the types supported by the cell are
@see #CELL_TYPE_NUMERIC
@see #CELL_TYPE_STRING
@see #CELL_TYPE_FORMULA
@see #CELL_TYPE_BLANK
@see #CELL_TYPE_BOOLEAN
@see #CELL_TYPE_ERROR
Of course, it should be noted that when using NUMERIC, you need to consider whether it is a date. You can use DateUtil.isCellDateFormatted(cell) to verify whether it is a date type
