Would it be an option for you to embed the spreadsheet into one of your Wild Apricot pages using html? On google support https://support.google.com/docs/answer/37579, it says you can:

1: Open a file in Google Docs, Sheets, or Slides.
2: At the top, click File and then Publish to the web.
3: In the window that appears, click Embed.
4: The entire file will be published, but some file types have more publishing options:
Spreadsheet: Choose to publish the entire spreadsheet or individual sheets.
Presentation: Choose a presentation size and how quickly to advance the slides.
5: Click Publish.
6: Copy the code in the text box and paste it into your site or blog.

It should give you some HTML to represent your Google Spreadsheet. If you edit a text box on your Wild Apricot page, there should be an <S> button in the edit toolbar (or you could use the HTML button next to it). If you click on either of these, it should allow you to paste the embed code for your Google Spreadsheet into that text box. Is this what you are trying to do?
