Text (forced) stores the value as a string with an explicit text format, so Excel can't reinterpret it. Use this for postcodes, phone numbers, membership numbers with leading zeros, and any ID-like field. Number and Date convert the value to a true Excel number/date type for correct sorting and formulas.
