I split data sorted by a column to divide for analysis by several, ea w/ many rows. To rejoin, I need to paste at row x, not at top. How? I get an error pasting not at the top-left corner. Seems... troublesome.

If a file of a previous version of Office 365 shared document, cannot be opened because it says that it does not support features like Scenario manager, then one should be warned when saving such file, or it should be adjusted to accept such features. Or fix so it can accept the features.

There should be an option to chat with other contributors on the sheet.

useless in share point.

Add checkboxes as they help collaboration and check off done items when working on a group project.

It would be good to have a way to notify person who has locked the file out that is shared to close it by clicking a button

When clicking on an Excel link, Excel in the browser is opened. Then when it has started (which is slow for large spreadsheets) you have to click on the "Open in Excel" button and wait again. Can we please have a "Remember my choice" or something like that so that we can choose to always open an Excel file in Excel directly?

Duplicating Pivot tables could be very interesting when we communicate with multiple colleagues

Please allow use of @username in comments in online Excel, such that someone can be directed to a given cell in case they need to be made aware of some information or a task can be assigned to that user. E.g. if someone needs to add some content, or confirm content, they would get an email to look in a particular cell or row to edit or confirm.

We are sharing a quote builder and have 40 sales people who use this excel doc with co authoring we cannot do this.

when someone modifies a shared file, have the ability to alert the other people who share the file ( if they chose) .

please authorize duplication of pivot tables

Allow viewing and editing of SmartArt on Excel Online. Some users use SmartArt heavily and they would like to be able to collaborate on them online

Same functionality is available in google sheets/slides. By entering ***@email.com and adding a task the person will get a notification via email that there is task for him/her to resolve. Once resolved he/she can directly mark the comment as resolved and the initiator gets a notification that this is done

Please add a functionality that would enable the locking of cells, rows or columns for a specific user/s.

Allow the file author (originator / admin) to reject or unwind any change made by others to his/her Excel file.

It would be great if you could see who the last person was to edit any given cell. being that many people can be editing the document it would be great help to see who, and when, a given cell was last edited.

How about listening to users and add in "personal filters" when multi-tasking and correct regional date, number and currency settings?? These ideas have multiple separate entries in the list below.

Being able to Ctrl C copy a cell's information - otherwise I have to open it up in Excel, set to edit and then copy the cell data.

Please make this default unless opted out for security reasons.

Create exception to bypass minor versions limitations when an Excel file is meant to be edited/filled in by many users.

There is an Excel file which users are meant to fill in to state whether they need a certain role etc. The list has many users listed. So it is bound to be saved and resaved many times. When the number of minor versions limit is reached, the creator of the Excel file needs to clone the Excel file.
