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.

GemBox.Spreadsheet - provides easy, elegant and high performance way to create, convert, write to and read from Excel files GemBox.Spreadsheet is a very useful .NET component which provides easy, elegant and high performance way to create, convert, write to and read from native Microsoft Excel files (XLS files in BIFF format or CSV files in text format) without the need for Microsoft Excel on either the developer or client machines.
With Microsoft Office installed on most business desktops it is tempting to use Microsoft Excel object for XLS file reading / writing.
Performance. In the case of desktop application, you dont want your user to wait 20 seconds for every single report. In the case of web application, you want your server to simultaneously support as much users as possible. Our test programs generate single XLS file with 200 rows and 100 columns of tabular data. Half of the values are strings and half are numbers, with 50% of cells having some cell style applied (font size and border).
100% managed code. Many of the competing products (and actually Microsoft Excel object) are old COM components with .NET RCW (Runtime Callable Wrapper). That brings many performance and interoperability disadvantages as every method call you make goes through the wrapper until it reaches C++ code. On the other hand, our GemBox.Spreadsheet component is 100% managed, written entirely in C# and designed to support both Visual Basic .NET and C# in equal manner.
Clean and easy to use API. GemBox.Spreadsheet is a designed and developed to conform to Microsoft standards for .NET libraries.
Version restrictions:
- Maximum number of rows per sheet is 150.
- Maximum number of sheets per workbook is 5.
