How to get reminder in mail through vab

You want to know how to set up a reminder in Gmail using VBA (Visual Basic for Applications) in Microsoft Excel.

Here's a step-by-step guide to help you achieve this:

Prerequisites:

1. You have Microsoft Excel installed on your computer.
2. You have a Gmail account and know your login credentials.
3. You have basic knowledge of VBA programming.

Step 1: Enable Gmail API in Google Cloud Console

1. Go to the Google Cloud Console (https://console.cloud.google.com/).
2. Create a new project or select an existing one.
3. Click on "APIs & Services" and search for "Gmail API".
4. Click on "Enable" to enable the Gmail API.
5. Create credentials for your project by clicking on "Create Credentials" > "OAuth client ID".
6. Choose "Other" as the application type and enter a name for your client ID.
7. Click on "Create" and copy the client ID and client secret.

Step 2: Set up Gmail API in Excel VBA

1. Open Microsoft Excel and create a new workbook.

2. Press Alt + F11 to open the Visual Basic Editor.

3. In the Editor, click on "Insert" > "Module" to insert a new module.

4. Paste the following code into the module:

   Sub SendReminderEmail()
    Dim objHTTP As Object
    Dim strURL As String
    Dim strBody As String
    Dim strSubject As String
    Dim strFrom As String
    Dim strTo As String
   
    ' Set up Gmail API credentials
    Const clientId As String = "YOUR_CLIENT_ID"
    Const clientSecret As String = "YOUR_CLIENT_SECRET"
    Const refreshToken As String = "YOUR_REFRESH_TOKEN"
   
    ' Set up email details
    strSubject = "Reminder: [Your Subject]"
    strBody = "This is a reminder: [Your Message]"
    strFrom = "[email protected]"
    strTo = "[email protected]"
   
    ' Set up HTTP request
    Set objHTTP = CreateObject("MSXML2.XMLHTTP")
    strURL = "https://www.googleapis.com/gmail/v1/users/me/messages"
    objHTTP.Open "POST", strURL, False
    objHTTP.setRequestHeader "Authorization", "Bearer " & refreshToken
    objHTTP.setRequestHeader "Content-Type", "application/json"
   
    ' Set up JSON payload
    Dim jsonPayload As Object
    Set jsonPayload = CreateObject("Scripting.Dictionary")
    jsonPayload.Add "to", strTo
    jsonPayload.Add "from", strFrom
    jsonPayload.Add "subject", strSubject
    jsonPayload.Add "body", strBody
   
    ' Send HTTP request
    objHTTP.send (jsonPayload.Text)
   
    ' Clean up
    Set jsonPayload = Nothing
    Set objHTTP = Nothing
   End Sub

   Replace YOUR_CLIENT_ID, YOUR_CLIENT_SECRET, and YOUR_REFRESH_TOKEN with your actual Gmail API credentials.

Step 3: Set up reminder

1. In the Excel worksheet, create a cell with the reminder date and time you want to send the email.
2. In the VBA module, add the following code to the SendReminderEmail subroutine:

   If DateValue(ActiveCell.Value) = Date Then
    Call SendReminderEmail
   End If

   This code checks if the current date matches the reminder date and time. If it does, it calls the SendReminderEmail subroutine to send the email.

Step 4: Save and run the macro

1. Save the workbook with a .xlsm extension (e.g., "ReminderEmail.xlsm").
2. Close the Visual Basic Editor.
3. Open the workbook and go to the "Developer" tab (or press Alt + F11 to open the Visual Basic Editor again).
4. Click on the "Run" button or press F5 to run the SendReminderEmail subroutine.

The email will be sent to the recipient at the specified date and time. Make sure to test the code and adjust the email details and API credentials as needed.
