The application provides two separate windows, one for the actual conversion and the other for choosing the type (string, integer, float, double or array) in each key (type, category and name). In the process, you can also choose the encoding type and select the type for each key in the resulting JSON or PLIST files.
Data File Converter is a simple and minimalistic Mac OS X application that enables you to quickly convert CSV, JSON, PLIST and TSV files to the JSON and PLIST formats.
