No longer able to open .docx and .xlsx files from Trello app on Macbook
Asked by Rachel McLaughlin:

Until two days ago, I was able to open .docx and .xlsx files directly from the Trello app (admittedly, it was a little buggy). Now when I try, the files download via my browser. I've uninstalled/reinstalled the Trello app and repaired/reinstalled the Office software. I'm using a Macbook running Big Sur with Word and Excel for Mac and the Trello app installed. Is there a fix or a way around this?

Hope this helps!

body: This is fantastic. Thank you Adam for adding this. Each of my cards have several files attached, some of them Excel invoices. So, not being forced to downalod it is a huge, positive gamechanger (as was the summer down/upgrade that disabled it).

Any chance you could add .xls extension? Most of my cards have that, but seems like it is working only with .xlsx.

Regarding your external share, it is also extremely helpful. If there is any way to keep the upload date when this is enabled, that would be wonderful.

The Tiny Power Ups are worth every penny!

body: BTW, [@Adam Cao](/t5/user/viewprofilepage/user-id/4458333) since we now can't preview PDF (which was disabled some time ago), that would be also good to add.

Frankly, I can't even preview JPG or MP4, and I am not sure if this is a problem localized to my computer, or if all attachments across the board were disabled.

Thank you again for your work restoring the functions we were used to have.

I've added .doc, .xls, and .ppt to the supported extensions list of Office File Viewer. Let me know if it works for you!

I've updated External Share to display the upload date next to the Share button.

I'm pretty sure that this is a bug that was introduced by the External Share Power-Up. I will try to find some time this weekend to fix this issue. Thanks for pointing this out!

Cheers! ?

body: Thank you, Adam for adding the extensions, and the dates. Works perfectly.

I tested the Image preview and you are right, I can preview them on boards where the tiny powerups are not enabled.

[@Carrie Barton](/t5/user/viewprofilepage/user-id/4524110) I do find it unfortunate that the update over the Summer was not so much an update for many of us, but with Adam's solution priced at $1 per month this is for our organization absolutely no brainer. Plus, his fast response to the issues I pointed out is very much appreciated.

body: [@Adam Cao](/t5/user/viewprofilepage/user-id/4458333) some time ago we were chatting about attachments and I see that there is still the bug you mentioned. When I click on any jpg or pdf under card's attachments, it opens in a new browser tab.   
However, if I open it from the card's feed, it opens in Trello.   
MP4 that used to open in Trello always opens in a browser.

As I mentioned, your power up is extremely useful, but if there is any way to fix it, it would be even better.

body: I am also trying to find a solution as I need to preview on a regular basis Excel files.

Unfortunately, this is a part of an "upgrade" that seriously devaluated Trello for us. Apparently this is not the end. The following is an answer I got:

*. I'm sorry to report that boards will slowly be changing to only allow the preview of video and image files. PDF, docx, xlsx, pptx, and other files that are not video of image types will not have an option to preview them any longer.*

I expect that the turn off of PDF preview will be a huge problem as many companies are using Trello for approval, etc. the lack of preview of files will be a problem for many.

body: I saw this on another post as well. Removing this ability would be a major blow. I have typically championed Trello over Teams, but the tide will shift if they continue to remove these features.
