Build a Excel VBA macro that pull historical price data from Kraken

Hi, I am looking for someone comfortable with Excel VBA programming and used to working with API to source data from a website. The project is to build a simple spreadsheet that will import the historical prices and volumes from [login to view URL] (the cryptocurrency exchange) for any given pair available on the exchange as specify by the user. The user will have to input three things in the spreadsheet: - The pair he is interested in (e.g. ETH/EUR, XRP/BTC, etc.) - this is probably two inputs - The desired time interval between each prices (e.g. 5 minutes, 1 hour, etc.) - The desired period to cover (e.g. last 24 hours, last month, from 01-Jan-2017 to 31-Dec-2017, etc.) Then, the user will click on a button that will execute a macro which will pull the corresponding data from Kraken . The output is a spreadsheet that should include the following 6 columns: time, opening price, closing price, high price, low price, volume. Here is the Kraken API manual: [login to view URL] This is not the Kraken API, but could probably work as well: [login to view URL] If you think you could help with that, that would be super helpful :) Thank you and do not hesitate to get in touch if you have any question!
