Transforming spreadsheet data types using examples
Cleaning spreadsheet data types is a common problem faced by millions of spreadsheet users. Data types such as date, time, name, and units are ubiquitous in spreadsheets, and cleaning transformations on these data types involve parsing and pretty printing their string representations. This presents many challenges to users because cleaning such data requires some background knowledge about the data itself and moreover this data is typically nonuniform, unstructured, and ambiguous. Spreadsheet systems and Programming Languages provide some UI-based and programmatic solutions for this problem but they are either insufficient for the user’s needs or are beyond their expertise. In this paper, we present a programming by example methodology of cleaning data types that learns the desired transformation from a few input-output examples. We propose a domain specific language with probabilistic semantics that is parameterized with declarative data type definitions. The probabilistic seman...
