To make the HTTP request asynchronous in VBA, you can use the XMLHttpRequest object instead of the execShell function. The XMLHttpRequest object allows you to make asynchronous HTTP requests, which means your VBA code won’t freeze while waiting for the response.
Here’s how you can modify the SendDataToGoogleSheet function to use XMLHttpRequest:
Public Sub SendDataToGoogleSheetAsync()
jsonData = "{""field1"":""Value1"",""field2"":""Value2"",""field3"":""Value3""}" ' Customize with your data
' URL of your Google Apps Script web app endpoint
url = "YOUR_GOOGLE_APPS_SCRIPT_WEB_APP_URL_HERE"
' Create a new XMLHttpRequest object
Set xhr = CreateObject("MSXML2.XMLHTTP")
' Define the callback function for handling the response
xhr.OnReadyStateChange = CreateObject("ScriptControl")
xhr.OnReadyStateChange.Language = "JScript"
xhr.OnReadyStateChange.AddCode "Sub OnReadyStateChange(){If (xhr.readyState = 4 And xhr.status = 200) Then MsgBox(""Data successfully sent to Google Sheet."")}"
' Open a POST request to the URL
xhr.Open "POST", url, True ' True for asynchronous
xhr.setRequestHeader "Content-Type", "application/json"
Replace "YOUR_GOOGLE_APPS_SCRIPT_WEB_APP_URL_HERE" with the URL of your deployed Google Apps Script web app endpoint.
This code will send the POST request asynchronously, and the VBA code will continue executing without waiting for the response. When the response is received, the OnReadyStateChange event handler will trigger, and a message box will be displayed indicating that the data was successfully sent to the Google Sheet.
