gdata-python-scripts collects some simple scripts and examples that use the Google Spreadsheets Data APIs client libraries for Python. The main goal is to collect and publish small snippets of code that, if not completely general and ready to use, remain simple enoguh (and hopefully well documented enough) to be adapted to your own needs.
Data Validator is a class to validate a set of values based on a list of rules. It supports the following validation orders: sequence (fields validated sequentially), all-at-once, and both (using a dependencies model). It can embed different user-defined validation rules libraries (a default built-in library is provided).
