VBA Interact with HTML + WebBrowser

The original idea from this post came from this another one. But I needed to have it extended to any other functions, and to deal with Gmail two steps login.

To interact with HTML pages and its controls we need to add two references in our Excel VBA.

  1. Microsoft HTML Object Library (mshtml.tlb): This library is required to access all HTML controls which can be present on your HTML page.
  2. Microsoft Internet Controls (ieframe.dll): This reference is required to do operations on Internet Explorer because to open an HTML page we need to access Internet Explorer.

How to Add Reference in Excel

  1. Go to VB Editor Screen (Alt+F11)
  2. Tools –> References…
  3. From the List of Available References Select your Reference Name which you want to add.
  4. Note: If you are not able to find the Reference Name in the list then Click on browse and select the dll name which is given for those Reference Names.
  5. Click OK

The VBA WebBrowser project

It will look something like these:


ToDo: detect where is the mouse pressing down and find object in that X,Y position, so inner HTML code can be recalled and copied to clipboard.

Paste inside the UserForm code the following, and add the neccesary objects that warns when loaded.

Some hints about how to deal with HTMLElements:
Debug.Print objIE.document.getElementsByTagName(“p”)(0).innerHTML ‘ displays inner HTML of 1st p element on a page.

Debug.Print objIE.document.getElementsByTagName(“p”)(4).textContent ‘ displays text content of 5th p element on a page.

‘clicks an input element that has a value equal to ‘Sign In’
For Each ele In objIE.document.getElementsByTagName(“input”)
If ele.Value = “Sign In” then ele.Click: Exit For

‘gets the link element containing ‘wp-admin’ and navigates to it.
For Each ele In objIE.document.getElementsByTagName(“a”)
If InStr(ele.href, “wp-admin”) > 0 then objIE.navigate ele.href: Exit For


One thought on “VBA Interact with HTML + WebBrowser”

  1. Nice post. I was checking constantly this blog and I’m
    impressed! Very useful info specially the last
    part 🙂 I care for such information a lot.
    I was looking for this particular information for a very long time.

    Thank you and best of luck.
