Abstract

Current prescriptions for spreadsheet style specify modular separation of data, calculation and output, based on the notion that writing a spreadsheet is like writing a computer program.

Instead of a computer programming style, this article examines rules of style for text, graphics, and mathematics. Much "common wisdom" in spreadsheets contradicts rules for these well-developed arts.

A case is made here for a new style for spreadsheets that emphasises readability. The new style is described in detail with an example, and contrasted with the programming style.
