Free spreadsheet excel software for windows

Spreadsheet Composer is an Excel add-in, which offers significant productivity and development benefits. The core capability of the add-in is the compose function.
With this function it is possible to define a spreadsheet calculation as a series of linked steps and then automatically compose the calculation into a single complex formula. Spreadsheet Composer is a very powerful tool that enables the user to attain a level of functionality and error trapping that was previously difficult to achieve in a manageable spreadsheet.
The add-in provides a number of support features to facilitate the use and management of composed formulae. It provides a database for the storage; documentation and retrieval of formulae and a matching function that can link an implemented formula back to its database description.
The retrieval function allows the user to copy a formula from the database into a selected spreadsheet cell, to automatically select input cells for the formula and to specify a mix of relative and absolute addressing for the selected cells.
The add-in permits complete verification of a formula before it is stored within the database. The formula can be verified against its original definition and against its intended behaviour. If a formula gives an unintended output for a particular combination of inputs, then additional error trapping can be factored into the composed formula.
The add-in provides an export function, which allows a completed spreadsheet to be written out to a standalone workbook for independent operation.
