Help with Elasticsearch Bulk API (Using Windows 7)

I was going through the Kibana "Getting Started" Examples on I am running Windows 7.

The examples show that 3 data files need to be loaded into my elasticsearch cluster. shakespeare.json, accounts.json and logs.jsonl Getting Started describes using the Elasticsearch Bulk API to load the 3 data files into my elasticsearch cluster.

How do I use the ElasticSearch Bulk API to load the 3 data files using Windows 7? I do not use curl. Instead I have Fiddler, Postman, and Logstash installed to do most of my loading of data into elasticsearch.

Why not Java API
