Excel online doesn't allow users to filter without filtering the document for all rest of users. This is a key feature for shared documents so every user can filter and modify only the desire information without having to scroll or search.
Also Excel online currently doesn't handle medium/big files. Files with 2.700 KB take long time to open and don't work well.

Without Filter View, collaborators are constantly seeing their view change as other collaborators filter on their work. This makes what could be a much needed file unusable for more than 2-3 users. In our team of 20+, users have to save local copies to even work with the file. At that point, there isn't much value and its more of a headache than anything. Private filter views where collaborator can work on the document without other users impeding their progress is absolutely necessary

Link automatically open in Excel online which doesn't work for many documents that have macros or are over a certain size. Give an option to open in Desktop Excel or just download the file instead without having to waste time trying to load it in Excel Online.

Desktop Excel is great, spreadsheet edit within SharePoint is TERRIBLE. I suggest ALWAYS opening .xls* files within the desktop app. Why even try to provide functionality within SharePoint?

A file system, collaboration site, and meetings do not work well together in large organizations as it creates data overload. Stop Team! I love Excel. To improve it, please remove it from MS Teams. I detest trying to work on files in MS Teams and want it to go away.

prevent users from downloading or printing shared files

shared worksheet should have detailed history just like gmail.

"Sheet View" is a great feature, but doesn't it require the user to remember to create the sheet view?

The problem is that if I send an invite to 100 people to collaboratively edit an Excel spreadsheet with filters, it only takes one of them to leave the filters in a nondefault state to ruin the party for everyone.

I suggest allowing the creation of a "Default" sheet view that is used whenever the sheet is opened online for collaboration. This would allow the default view to be fine-tuned by the spreadsheet maintainer.

I am unable to open files more than 25 MB over excel web in Teams Channels over Microsoft Teams , as per MS articles it should be 50 MB.

It takes too many clicks to open Excel files from online sources. It would be great to set a default of always using Excel on PC for files. Especially helpful since Excel online cannot open Macro enabled files.

Freezing should not be restricted to single row or columns. user can select as many as they can depending on thier choice of requirement

There is a black bar at the bottom of a oneDrive spreadsheet embedded in an iframe. It contains four icons, one of the left and 3 on the right for such functions as give feed back, info about the workbook, and view full size workbook. I would like to hide the options for "info about the workbook", and "view full size workbook". I only want web users to be able to see the area that I have specified.

Prevent changes to be made by two persons at the same time.

I would like to be able to right click and fill a selected cell with a color. I am currently having to select the desired cell and then go to the header block to select the color fill icon.
