Hello Question regarding embed url for excel files

Question

I tested displaying files via iframe specifically excel files like the code below.
the first iframe won't work, but the second iframe works for excel file?

1. What's the scope or limitation for this embed links?
2. I tried video, powerpoint, csv, text, pdf, and it all works via the first iframe url method, I'm just curious if this not only applies to excel files but to other files that I haven't tested yet? Do these apply for the following file types:
   a. Excel files (.xlsx, .xls, .xlsm, .xlsb) b. Word documents (.docx, .doc, .rtf) c. PowerPoint presentations (.pptx, .ppt) d. OneNote notebooks (.one) e. Visio diagrams (.vsdx, .vsd) f. Project files (.mpp)
3. For your Information, the top iframe url method is the given embed code by sharepoint itself, so i thought it would work but it did not.

<h1>Excel embed</h1>
<iframe src="https://mydomain/personal/username/_layouts/15/embed.aspx?UniqueId=[uniqueId here]&action=view" width="640" height="360" frameborder="0" scrolling="no"></iframe>

<h1>Excel doc.aspx, sourcedoc instead of uniqueId, with action=embedview</h1>
<iframe src="https://mydomain/personal/username/_layouts/15/doc.aspx?sourcedoc=[uniqueId here]&action=embedview" width="640" height="360" frameborder="0" scrolling="no"></iframe>

Hi @Aithan Gimenez ,

Per my test, I could reproduce your issue. We will need to use Doc.aspx?sourcedoc={uid} to dsiplay the excel. I would recommend you to genrate embed code by Excel spreadsheet. Please refer to the following steps

1.Upload the Excel spreadsheet to the SharePoint Online document library first. 

2.Open the Excel file in the Web browser (Excel Online) >> Click on File >> Share >> Embed.

3.In the Embed window, choose the content from the Excel spreadsheet you want to show, such as a Table, Range of Cells, or full workbook. You can customize further by setting other preferences by setting the respective checkboxes on the embed page. Copy the embed code generated once done.

And the generated code also use the format like your second url

Refer to this Microsoft Documentation for further help in setting parameters to the HTML iframe code.

The solution is for Microsoft to roll back to the old embed or tweek the new one to allow the selection of cells like before.
