Confluence failed to generate file preview after editing with Companion app


Here is the deal:

  1. I upload the word file to confluence page - preview works fine
  2. I edit the file with the help of a Atlassian Companion app - it saves/uploads the file without a problem
  3. The problem emerges after I save/upload the file and go back to page view. Confluence cannot generate preview no more for the file that has been edited. It shows the error message "Something went wrong. We couldn't generate a preview for this file." Disclaimer: if I edit another file on the page, the previous edited file goes back to normal, no problam previewing it.
  4. If I open the page's attachements I can view the files without any problems.

Below I have attached two pictures - one shows what I see after I save the file, the other shows the error message after I press on the file.


Software: Windows 10, Chrome Version 95, Confluence Cloud

Hi Ignas,

Welcome to the Atlassian community, and thank you for reporting this to us. I understand after you edit a Confluence page attachment in the Companion App, the preview breaks. 

Can you confirm if this page is on the legacy editor or the new editor? You can check Convert pages to the new editor to learn the difference visually.

Secondly, does it happen with any document type or only specific ones?

I hope to hear from you soon!

Take care,


Hi Shannon,

I see the same behaivor with an Excel-sheet.

And it seems that I'm using the new editor.

Cheers, Stefan

Hi Stefan,

Thank you for confirming you're having the same issue too. I'm so sorry about the trouble this is causing you. 

We will want to see the Excel document and the page to see why this might be happening. Can you raise a support ticket and attach the document as an example?

If you have any trouble creating a ticket, please let me know, and I can help you out.

@Shannon S sorry for late answer. The problem is with both excel and word documents; I did not test the other document types. I attach the picture below, where from left to right: edited excel file, unedited docx file, edited docx file. When pressed it fails to generate preview.


Also, I am confirming that the page itself is edited in new editor, not legacy.

Having the same "We couldn't generate a preview for this file." with office documents after updating them with companion.  Has anyone managed to resolve this?  Could be a deal breaker for us.

Hi @Tony

We reported this issue in the bug Ignas shared. Please follow the ticket CONFCLOUD-72339 for updates on its resolution. 

In the meantime, you can store the attachments on Google Drive. So, when you paste a Google Drive link into the page, you'll have an option to display embedded documents.

I hope that helps!

Take care,
