Answer:
Screener.co is a fully customizable global stock screener that includes both companies located in India as well as those that trade on the Indian stock exchanges. To limit your search to only companies located in India, you can launch the Screener.co stock screener and Add Criteria->Descriptive->Company->Country Located In and set it equal to India.
To limit your search to those on the Indian exchanges, click on the Markets menu in the upper left corner of the screen. Then, select the stock exchanges you want to include (i.e. Bombay, NSE, etc.).
