How to run Console C# app in specific time?

You could use a VM. That is a type of cloud. There are Windows VMs but Linux VMs are very abundant and you can use Visual Studio to develop a C# console application that can execute in Linux.

Here are example code snippets for the two approaches mentioned previously to run your C# console application every hour:

1. Deploying to a Cloud Server (using Azure App Service as an example):

C# Console Application: (This is just a sample; modify it to write to your Google spreadsheet)

using System;
using Google.Apis.Sheets.v4;
using Google.Apis.Sheets.v4.Data;

public class SpreadsheetWriter
{
    public static void WriteToSpreadsheet(string spreadsheetId, string range, string value)
    {
        // Replace these with your Google API credentials
        string clientId = "YOUR_CLIENT_ID";
        string clientSecret = "YOUR_CLIENT_SECRET";

        // ... Code to authenticate with Google Sheets API (omitted for brevity)

        var service = new SheetsService(new BaseClientService.Initializer()
        {
            HttpClientInitializer = new CredentialManager().GetCredentials(new ClientSecrets()
            {
                ClientId = clientId,
                ClientSecret = clientSecret
            })
        });

        var valueRange = new ValueRange();
        valueRange.Values = new List>() { new List
