Indian Stock Exchanges data Download

Looking to design a simple application similar to an already running program called getbhavcopy. The application should select a date range, market type and download to a local directory as a text file. The type of data are stock price data, commodities and currency. The application idea can be viewed at https://www.getbhavcopy.com/ The sample result file is also attached. The source code of the original project is available here at https://github.com/hemenkapadia/getbhavcopy
I need a similar design from the source code or a new application is fine, which can meet the data requirements. The source code can be later modified to accommodate other data downloads like currency and commodity. The location to scrap data is https://www.nseindia.com/all-reports
