# Excel to Code [](https://travis-ci.org/tamc/excel_to_code) excel_to_c - roughly translate some Excel files into C. excel_to_ruby - roughly translate some Excel files into Ruby. This allows spreadsheets to be: 1. Embedded in other programs, such as web servers, or optimisers 2. Without depending on any Microsoft code For example, running [these commands](examples/simple/compile.sh) turns [this spreadsheet](examples/simple/simple.xlsx) into [this Ruby code](examples/simple/ruby/simple.rb) or [this C code](examples/simple/c/simple.c). # Install Requires Ruby. Install by: gem install excel_to_code # Run To just have a go: excel_to_c <excel_file_name> This will produce a file called excelspreadsheet.c For a more complex spreadsheet: excel_to_c --compile --run-tests --settable <name of input worksheet> --prune-except <name of output worksheet> <excel file name> See the full list of options: excel_to_c --help # Gotchas, limitations and bugs 0. No custom functions, no macros for generating results 1. Results are cached. So you must call reset(), then set values, then read values. 2. It must be possible to replace INDIRECT and OFFSET formula with standard references at compile time (e.g., INDIRECT("A"&"1") is fine, INDIRECT(userInput&"3") is not. 3. Doesn't implement all functions. [See which functions are implemented](docs/Which_functions_are_implemented.md). 4. Doesn't implement references that involve range unions and lists (but does implement standard ranges) 5. Sometimes gives cells as being empty, when excel would give the cell as having a numeric value of zero 6. The generated C version does not multithread and will give bad results if you try. 7. The generated code uses floating point, rather than fully precise arithmetic, so results can differ slightly. 8. The generated code uses the sprintf approach to rounding (even-odd) rather than excel's 0.5 rounds away from zero. 9. Ranges like this: Sheet1!A10:Sheet1!B20 and 3D ranges don't work.

# DECC 2050 CALCULATOR TOOL A C version and ruby wrapper for the www.decc.gov.uk 2050 energy and climate change excel calculator Further detail on the project: http://www.decc.gov.uk/2050 Canonical source: http://github.com/decc/decc_2050_model ## DEPENDENCIES 1. ruby 1.9.2 (including development headers) 2. basic c development headers This has ONLY been tested on OSX and on Ubuntu 64 bit EC2 ami. Grateful for reports from other platforms. In the util folder there is an example script that creates a new EC2 EMI, installs all the dependencies and then compiles the gem. It may be useful if you are trying to figure out the complete set of dependencies. ## INSTALLATION Note that this compiles the underlying c code, which might take 10-20 minutes or so gem install decc_2050_model ## UPDATING TO NEWER VERSIONS OF EXCEL MODEL First of all, you need to be working on the github version of the code, not the rubygem: git clone http://github.com/decc/decc_2050_model Then put the new spreadsheet in spreadsheet/model.xlsx Then, from the top directory of the gem: bundle bundle exec rake The next step is to check whether Rakefile, lib/model/_model_result.rb and lib/model/model_structure.rb need to be altered so that they pick up the correct places in the underlying excel. The final stage is to build and install the new gem: gem build model.gemspec gem install decc_2050_model-<version>.gem ... where <version> is the version number of the gem file that was created in the folder. Now follow the instructions in the twenty-fifty server directory in order to ensure that it is using this new version of the gem.

Soroban makes it easy to extract and execute formulas from Excel spreadsheets. It rewrites Excel formulas as Ruby expressions, and allows you to bind named variables to spreadsheet cells to easily manipulate inputs and capture outputs.

Extend Rails capabilities of importing and exporting excel files thanks to Spreadsheet gem

Axlsx_Rails provides an Axlsx renderer so you can move all your spreadsheet code from your controller into view files. Partials are supported so you can organize any code into reusable chunks (e.g. cover sheets, common styling, etc.) You can use it with acts_as_xlsx, placing the to_xlsx call in a view and adding ':package => xlsx_package' to the parameter list. Now you can keep your controllers thin!

Grateful for reports from other platforms. In the util folder are two example scripts than can be helpful: 1. start-high-memory-instance.sh - is the script we use to setup an aws server to compile the model. You can't use it directly, because you won't have the right keys and certificates, but it can give clues. 2. setup-2050-model-builder-script.sh - is the script we use to get all the dependencies on that aws server correct, download this code, and then compile the model. Again, it may not be quite right for you but can server as inspiration ## INSTALLATION Note that this compiles the underlying c code, which might take 10-20 minutes or so gem install decc_2050_model ## UPDATING TO NEWER VERSIONS OF EXCEL MODEL First of all, you need to be working on the github version of the code, not the rubygem: git clone http://github.com/decc/decc_2050_model Then put the new spreadsheet in spreadsheet/2050Model.xlsx Then, from the top directory of the gem: bundle bundle exec rake The next step is to check whether lib/decc_2050_model/decc_2050_model_result.rb and lib/decc_2050_model/model_structure.rb need to be altered so that they pick up the correct places in the underlying excel.
