If you're using Microsoft's Sway and you want to insert an Excel spreadsheet, there's just a couple easy steps to do it.
Create a new Sway and give it a title. I've called this one Embedding an Excel Spreadsheet.
Next, click the plus sign to add more content. Choose the Media group then click the Embed option.
Sway is now waiting for the embed code. You need to get the code from Excel after you've uploaded it to OneDrive (or created it online to begin with). So, assuming you've uploaded your Excel flle, we're going to step forward from that point. If you haven't done that, you need to open up OneDrive and upload it.
In the online Excel workbook, go to Share and embed and the code is ready at the bottom of the next window. You will be presented with a screen to select different parts of your spreadsheet, leave it at the default for now. Copy the embed code from your clipboard and go back to your Microsoft Sway. Go to the box waiting for your input, and paste the code.
You've embedded that Microsoft document. This is live. If you were to update this in Excel, this document that's showing here would be updated. You can also interact with this document to a certain extent with the icon lower right hand corner. You can download it or print it.
