It would be nice for links between spreadsheets on my One Drive to work.

Add ability to open Online files with more than 10 MB and increase file size to 30-40Mb

The online version of Excel doesn't allow the drop-down box option to work in files.

Our group just recently started using OneDrive for collaboration of an Excel document that we use on a daily basis. However, when trying to edit the document in the Browser, only one color can be applied to a cell. When using Excel in a local file, you can have more than one font color in a single cell by highlighting the targeted words in the cell and then choosing a different color.

Recommendation: Make it possible to have multiple colors in a cell when editing an Excel document in browser like you can do in a local file.

Currently, there is not the ability to lock certain cells in a document online, while also being able to edit others in the same sheet. It would help a ton if there was a way to lock specified cells in a sheet and also be able to edit unlocked cells in the sheet when editing online.

Generate the baility to multi user edit concurrently on the same file for both Excel online and application. Currently there is no true multi user editing as anytime a file is accessed even with multiple users enabled it still locks the file and cannot be edited by others.

Like the desktop version, when a formula is being edited (F2), highlight with colors the other cells used in the formula.

like other email websites (gmail, etc), excel online should also have feature to open password protected files without download to the pc, it should be open online by entering the file password

With the current version of Excel Online, once you change the font color of a particular text in single cell it automatically changes the font color of every text or data in that cell.
It would be handy if we could use different colors for the text in one cell

Please allow Filtering & Sorting by color, like the PC version

I use Excel to color code our schedules for work and It would be really helpful if there were more color options or the ability to create custom colors.

Currently, when you cut and 'insert' rows, it pastes over existing rows and information. The insert function should insert the rows and move the existing rows down.

When editing an Excel Online documents, hitting [ENTER] will drop you down to the next row, same column. Generally hitting [ENTER] will return you to the next row, but in the column your previous modified cell was in.

It would be really nice if we could create and edit custom rules for Conditional Formatting in Excel Online, similar to how we can in the Desktop version of Excel.

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.

Multiple text color in current excel online is unavailable.
The multiple color text will ease the editing & online coworking experience, especially in emphasizing a point without turning everything into the same color.
Really hope to see this improvement updated soon.

As with the 'offline' version, be able to protect sheets/workbooks and allow editable ranges.
Excel Online defaults to protecting the entire sheet,
As shared excel files/reporting are a large part of the new apps (MS Teams) it would make sense that this feature is included in the Online Excel version.

if I click on a excel file, I would like the excel to open in excel and not online. how can I stop excel online. is there a way we can get rid of this online nonsense.

When using Google Sheets to collaborate there is a filter view that allows you to set a filter view that only you see. This is very helpful when multiple people are in a file and you don't want to mess with the view everyone else is in. Something similar would make online excel much more user friendly.
