A system architecture integrates spreadsheet functionality into text. The architecture allows insertion of discrete individual fields, referred to as "free floating fields", inline with normal textual sentences. The free floating fields offer spreadsheet functionality, including the ability to handle complex formulas, reference values in a separate free floating field or table, and automatically recalculate the formulas when a source value changes. The values and formula results can also be formatted (e.g., numbers, date, times, currency, etc.), like a spreadsheet, while remaining part of the normal text of a document. The architecture also has a spreadsheet functionality manager to manage the spreadsheet functions for the free floating fields, such as recalculation, formula handling, sorting, referencing, and the like.
