spreadsheet_architect - Spreadsheet Architect is a library that allows you to create XLSX, ODS, or CSV spreadsheets super easily from ActiveRecord relations, plain Ruby objects, or tabular data

•    Ruby

---

Spreadsheet Architect is a library that allows you to create XLSX, ODS, or CSV spreadsheets super easily from ActiveRecord relations, plain Ruby objects, or tabular data. When NOT using the :data option, ie. on an AR Relation or using the :instances option, Spreadsheet Architect requires an instance method defined on the class to generate the data. It looks for the spreadsheet_columns method on the class. If you are using on an ActiveRecord model and that method is not defined, it would fallback to the models column_names method (not recommended). If using the :data option this is ignored.

django-rest-pandas - 📊📈 Serves up Pandas dataframes via the Django REST Framework for use in client-side (i

•    Python

---

Django REST Pandas (DRP) provides a simple way to generate and serve pandas DataFrames via the Django REST Framework. The resulting API can serve up CSV (and a number of other formats) for consumption by a client-side visualization tool like d3.js. The design philosophy of DRP enforces a strict separation between data and presentation. This keeps the implementation simple, but also has the nice side effect of making it trivial to provide the source data for your visualizations. This capability can often be leveraged by sending users to the same URL that your visualization code uses internally to load the data.

readxl - Read excel files (.xls and .xlsx) into R 🖇

•    C++

The readxl package makes it easy to get data out of Excel and into R. Compared to many of the existing packages (e.g. gdata, xlsx, xlsReadWrite) readxl has no external dependencies, so it’s easy to install and use on all operating systems. It is designed to work with tabular data. readxl supports both the legacy .xls format and the modern xml-based .xlsx format. The libxls C library is used to support .xls, which abstracts away many of the complexities of the underlying binary format. To parse .xlsx, we use the RapidXML C++ library.
