The purpose of this open source software is to provide a solution to personal expense report.

This solution includes a Google Spreadsheet where all expenses are reported, and a Telegram bot integration that allows to view the latest expenses, the total of expense and to add or delete expenses. The delete expenses feature has yet to be implemented for the Mr.RIP compatibility version of this bot.

• ✅ Useful dashboard to keep track of your expenses total
• ✅ Easy personalizable expense categories
• ✅ Data validation in expense sheet
• ✅ Telegram bot integration with security protocol to avoid unexpected unknown users interaction
• ✅ Compatible with Expenses-spreadsheets organized in Categories and Subcategories (e.g. Mr.RIP, you can take a look at his spreadsheets here and his blog here!)

Dashboard	Expenses

Personalizable categories	Telegram Bot Main Menu

Telegram Bot Total Expense	Telegram Bot Add new expense

Create a local copy to your Google Drive of the following spreadsheet:

• 👉 Copy Spreadsheet from original repo
• 👉 Copy Spreadsheet from mr.rip expenses spreadsheet

Remember to save your !!LOCAL COPY!! Google Spreedsheet Id because will be used in the next steps. e.g.: https://docs.google.com/spreadsheets/d/1VyCrEkmIRz4T_TmcKiy__y4NPLEFspRelXOKIIBrvbI/edit#gid=479673556 The spreedsheet id is '1VyCrEkmIRz4T_TmcKiy__y4NPLEFspRelXOKIIBrvbI' <- This is just an example, you will have definetely a different Google Sheet Id, don't use this otherwise the Telegram Bot integration will not work

PAY ATTENTION: If you change any sheet name you'll need to update Telegram bot js code as well.

If you want to integrate the Google Spreadsheet with Telegram, proceed with creating a Telegram Bot.

• 👉 How to deploy an App Script

In order to integrate Telegram Bot with Google Sheet we need to personalize the App Script with the tokens saved in the steps above mentioned

Insert the telegram token saved in step '2. Create a Telegram Bot' into the variable 'token' as follows:

/**
 * @var token
 * @brief 1. Fill with your own Telegram Bot Token Id
 *        (e.g. 521xxxx7165:AAHxxxxxxxxjbHr5l-m8rGxxxxxxwbk)
 */
var token = "521xxxx7165:AAHxxxxxxxxjbHr5l-m8rGxxxxxxwbk";

Insert the web application url saved in step '4. Deploy App Script as Web Application' into the variable 'webAppUrl' as follows:

/**
 * @var webAppUrl
 * @brief 2. Fill with your google web app address
 *        (e.g. https://script.google.com/macros/s/AKfycbwHkLLHeAY-07_A2dmXftSX0JNR8gTpeREQmzo2j2aWmItIuSsFSYzlB1bJNw0Dovd3qw/exec)
 */
var webAppUrl = "https://script.google.com/macros/s/AKfycbwHkLLHeAY-07_A2dmXftSX0JNR8gTpeREQmzo2j2aWmItIuSsFSYzlB1bJNw0Dovd3qw/exec";

Insert the Google Spreedsheet Id saved in step '1. Copy Google Spreadsheet' into the variable 'ssId' as follows:

/**
 * @var ssId
 * @brief 3. Fill with Google Spreadsheet Id
 *        (e.g. 1f_IT_kAFIG0TUOZyXL3nW67fxvd0fuSaw6gbAbtxzEo)
 */
var ssId = "1f_IT_kAFIG0TUOZyXL3nW67fxvd0fuSaw6gbAbtxzEo";

Insert the locale settings according to your preferences:

/**
 * @var locale
 * @brief 4. Set your locale for date time parsing
 *           e.g. it-IT
 *           e.g. en-US
 */
 var locale = "en-US";

Insert the timezone settings according to your preferences:

 /**
  * @var timeZone
  * @brief 5. Set your timezone for proper date formatting
  *           e.g. "Europe/Rome"
  *           e.g. "America/New_York"
  */
 var timeZone = "America/New_York";

Insert the currency settings according to your preferences:

 /**
  * @var currency
  * @brief 6. Set your currency
  *           e.g. "$"
  *           e.g. "€"
  */
 var currency = "$";

After those personalization we need to update the App Script deployment.

• Click on New Version

After having deployed the script, you've to execute 'getMe' and 'setWebhook' functions from Google Apps Script

Send a chat to your personal telegram bot create in step '2. Create a Telegram Bot' with any text

The bot will reply with:

⛔️ You're not authorized to interact with this bot!

Go to the Google Spreadsheet in "Logs" sheet, it will be present a new line as follows:

{
    "update_id": 642486188,
    "message": {
        "message_id": 765,
        "from": {
            "id": 8XXXXXXX6,
            "is_bot": false,
            "first_name": "XXXXXX",
            "last_name": "XXXXX",
            "username": "XXXXXX",
            "language_code": "it"
        },
        "chat": {
            "id": 8XXXXXX6,
            "first_name": "XXXXXX",
            "last_name": "XXXXX",
            "username": "XXXXX",
            "type": "private"
        },
        "date": 1644745924,
        "text": "Hello!"
    }
}

Copy the value of the field message.from.id, in this example has been censored as '8XXXXXXX6' and paste it to the sheet 'Authenticated Users' as follows:

Now send another message to your Telegram bot and it should reply to you with the main menu, and then you're ready to go with your Telegram integration!
