Enable support for creation, refresh and modification of Pivot Tables and Slicers in iPad and Android.

we need (I'm not alone!!) as soon possible the possibility to use Excel with macro (and VBA) on Tablet and Mobile

Allow for two documents to be open at the same time.

Existing conditional formatting works when opened on Android version, but there is no option to create new from the Android app.

Good afternoon! We would like the Data Validation Tool to be available. I miss this tool in Excel, so I have to use other means and other applications to do my tasks. It would be great to make data validation available.

It would be most useful to be able to create new documents from custom templates in Excel and Word on mobile devices.

Enabling form controls would allow iOS users to use buttons to enter information with a touch rather than having to type entries.

I'm imagining the power of being able to use the increment buttons, or radio toggles to collect data to quickly.

Even better would be coming up with cell formats that would accept that sort of input directly, without having to setup up the form controls. Imagine a checkbox format, or a counter format with Increment buttons.

Currently, cannot edit names of ranges or tables. Naming is an extremely helpful feature when dealing with other limitations of the mobile versions.

The ability to rotate text in a cell to varying degrees (at least 90) which is available in pc excel via edit cells - format -,rotate text....should be included ASAP. This feature used primarily in the header cells of a column where the filtered cells would be of limited width (I.e. 1 digit...or an “X”) allowing greatly increased utilization of limited viewing real estate.

Ironically, Google Sheets has even included this feature at this point (formulas were once required)...despite the app being barren in terms of features compared to xls in general.

Please add this staple functionality.

Please make the data analysis toolpak available to be added into the chromebook/mobile version of excel so I can do my stat homework on tablets.

iOS only allows a single sort column and needs the same sort and filter characteristics as the desktop versions

Please add the ability to add/edit headers in Excel.

It would be a lot better if you could lock and unlock spreadsheets whilst using an IOS device

I belong to an organisation the uses a Google account. All our documents are stored on google drive. MS Office doesn't support Google Drive as a "place" so I can't access and edit documents on google drive from Excel for iOS. I can open a spreadsheet from the Google drive app but it opens in Excel as read only and I can't save changes back to google drive.

Please add google drive as a "place" in MS Office apps for iOS.

Excel for PC and Mac, as well as the Surface Pro 3 and 4, have the Data Analysis Toolpack and Solver. We need these added to the iOS versions as well, please.

Not be able to protect/unprotected a sheet on my iPad is a serious limitation for me. It defeats the purpose of having multiple devices.

Not being able to Protect/Unprotect stuff with the android app is a big hindrance. If I am not in the office and I need to make a quick update to an excel sheet I am unable to since I cant unprotect the sheet. That means I have to wait until I get back to the office to do anything and sometimes it is a time sensitive issue that needs to be resolved asap. Implementing this into the android app would be a great addition and help streamline the experience.

I just posted this question to Microsoft forums and found out that this feature is still not functional in Excel for iOS:
I'm using Excel on an iPad Pro and would just tried to find a way to password protect a spreadsheet I'm saving to OneDrive. Searching the general web and these forums didn't readily surface an answer. I've seen old responses indicating that it wasn't possible to password protect a single sheet in 2014; however, I'd be surprised if it's not even possible to password protect an entire spreadsheet in the latest version of Excel for iOS.

Enable users to store passwords to their spreadsheets securely in Excel app and unlock files using fingerprint scanner / retina scanner / face recognition depending on their smartphone / tablet specs.
