js-standard-style Dependency Status Build Status Coverage Status # Generate JSON Schema files from Excel Sheet


In Todays world, RESTful API's and JSON have become the format of choice for APIs and applications. Initillay, there was no common standard to describe the RESTful API's or request/response data strcutres on par with SOAP servcies (WSDL/XSD). To bring the same standards, JSON Schema came with specification and solved problem of describing RESTful API's clear, human- and machine-readable documentation.

However, JSON Schema is trickier to work with for many people. Creating the JSON Schema files manually is cumbersome and error prone. On other hand, tables are just simpler for people to understand and organize. More importantly, Excel provides great tools manipulating and organizing the table structure data.
