Compar excel spreadsheet

Objective: Create a simple Excel spreadsheet, using the data to extract directly from web pages. A / I need to get all the information, e can compare the different exchangers by a simple table. The type of data relating to cryptocurrency exchange price pairs in different markets. For example I want to include the BTC / USD rate of sites like: [login to view URL], [login to view URL], [login to view URL] etc ... The total data I need about 10 exchanges with all available pairs (however, not all pairs exist based on each exchange). The site: [login to view URL] includes all the information I want (currency, pair, flight, price, update) B / Widget: I would like to filter some exchangers, same for pairs. C / Performance calculation: The price of the higher pair will be the reference for the other pairs to calculate the difference between each, including a deal with a reference price. Ex: Bittrex: ADA / BTC: $ 0.62 | Binance: ADA / BTC: -> [$ 0.65] <- | Poloneix: ADA / BTC: $ 0.61 Bittrex: ADA / BTC: ($ 0.65 -0.62 $) x500 = 15 | Binance: ADA / BTC: -> [$ 0.65] <- | Poloneix: ADA / BTC: ($ 0.65 -0.61 $) x500 = 20 Reference [500] D / In addition, the file should be easy to update with more pairs or markets in the future if needed. It might be possible to exclude pairs with a volume less than <100,000 for example I will provide you with a "model" with the various indications if necessary.
