Grabbing (parsing) info from Coinmarketcap.com, archiving and sending the result to Telegram and email.

[soprano]

Good day.
I present a template for obtaining information about cryptocurrency exchange rates.
The template retrieves information from the Coinmarketcap.com website - Name, Symbol, Price, Market Cap, Link
The result is saved in a .xlsx file, which is archived and then sent via email, and information about the completion of the process - to Telegram.
With free email services, email delivery does not work very well, so I recommend using your own domains and trying different ports - 25, 465, 587.

Input settings:

Get the necessary libraries from nuget.org:
using Ionic.Zip;
using HtmlAgilityPack;
using Newtonsoft.Json;
using Newtonsoft.Json.Linq;
using Telegram.Bot;
using OfficeOpenXml;
using OfficeOpenXml.Style;
using OfficeOpenXml.Table;
using Microsoft.Office.Interop.Excel;

The template is convenient to use for continuous monitoring of any changing data, with scheduling launches.
Of course, customize it to suit your needs.

All the best!
