If a spreadsheet is uploaded to Microsoft Teams and have been formatted in a current time zone or area code. DO NOT default it back to US. And once uploaded, keep that date or time format so when new entries are made in teams access to the spreadsheet it does not format back to a default US position screwing up all new date or time entries.

Allow field row and column colors to be updated without the need to open the program outside of teams.

In the desktop version of excel there is the option to switch between "Summary rows below detail" and "Summary rows above detail" when grouping cells (also known as outlining).

I would expect this functionality to also be within Excel Online.

On MS Excel, when an action can't be completed, a tip on how to go about it would help.

For example, while freezing panes, the pop up suggests that it's not possible to do it the way the user has chosen to do it. How about giving tips instead of how to do it?

Since to add a row and column and to delete a row and column is a routine practise for any Excel user either it's online or offline. So, to operate data in a much smoother way or to enter data with ease we must need a keyboard short cuts for Rows and Columns Addition and Deletion

would be awesome to support hotkey to quickly reformat text to "wrap text"

Format Cells --> Number tab --> Special --> Type: Phone number. The ability to format the number in the this format: +1 404 555 1234.

Currently clients are experiencing formating errors when creating a spreadsheet with vertical fonts using Excel Desktop application. When opening spreadsheet with Excel Online the vertical fonts are shown as horizontal fonts impacting on user satisfaction and experience. This is commonly an issue for customers saving a document in a SharePoint document library where the spreadsheet can be opened using Excel Online and / or the Excel desktop app. This is currently an Excel Online limitation.

Generate the ability for multiple users to edit documents in Excel online and application where the users can filter for their screen only. This would allow for greater collaboration as multiple pieces of a project can be worked on in the same document without each users view being altered by one users filter.

Allow formatting suchas columns in online application.

Also, allow to zoom in and out in excel

Add the ability to manage multiple conditional formatting rules in the web client, similar to desktop. Currently, the only workaround is to setup multiple rules in the desktop client and copy-paste the cells into a web-hosted document.

color and font themes need to carry over from excel offline.

Developers, please allow us to change specific text colors (i.e. 1 word) in a particular cell but allow the remaining text in that same cell to be a different color. This is not possible on the online Excel but is on the standard Excel. I hope you guys fix this as its a major functionality issue for many users like myself.

Shared Excel worksheets automatically change email addresses into hyperlinked version. Please allow a setting that globally TURNS OFF the hyperlink option.
As you navigate through cells, it opens new web tabs due to hyperlinks.

When a user opens a document for the first time, or the first time on a new device, a pop up window that allows the user to very quickly change the view to fit the new device/font/view.

This would not be a repeat service for the same user on same device, the traditional way of doing so would be optioned then.

I would like the option to customise the fill colour. I'd like to also be able to customise cells to add shading and gradient fill.

it would be great if we can lock/protect some column of an excel sheet?

YOUR VERSION OF THIS SUCKS
