# 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.

KPeg is a simple PEG library for Ruby. It provides an API as well as native
grammar to build the grammar.
KPeg strives to provide a simple, powerful API without being too exotic.

Modulation provides an alternative way of organizing your Ruby code. Modulation
lets you explicitly import and export declarations in order to better control
dependencies in your codebase. Modulation helps you refrain from littering
the global namespace with a myriad modules, or complex multi-level nested
module hierarchies.
