Quicker and easier to copy/move/delete data, as it is not bound by database table structure (records and fields), integrity rules etc. No need to create different objects (tables, queries, forms, reports), or to switch between views (e.g. De-sign and Datasheet), in order to process and present information –

19

the “working” view is also in “More useful error messages, if mistakes in calculations Easier and quicker to test “what-if” scenarios and trends More formatting and graphical options to present data (e.g. merged cells, borders, individual cell colours, text orientation) Can create charts/graphs
