Read ".xlsx" and convert date-column value into Dataframe
Those numbers are a "serial" number of days. A value of 1 maps to Jan 1, 1900. ref: https://support.office.com/en-za/article/DATE-function-e36c0c8c-4104-49da-ab83-82328b832349 A formula such as: as.Date('1900-01-01')+excel_date-1 should convert the serial value to a date value.
