Speeding up formula entry

We’ve sped up the time required for entering a formula in a cell by reducing memory usage, making more efficient memory allocation calls, and optimizing the redrawing of the visible range around the cell being edited. These optimizations are more noticeable on devices with slower memory or slower CPU-to-memory throughput.


June 1, 2022 | Version 16.0.15330.20006


AutoFilter is faster and more efficient

The AutoFilter function is now noticeably faster! These improvements were achieved by reducing memory usage and optimizing the filter’s comparison algorithm. The optimizations are especially noticeable on low-end devices that have less memory or slower CPU-to-memory throughput.

Office Mobile

Get Quick Access to your files

Browse through your content easily using the new Quick Access options now available on your Office home screen. Quick Access provides simple navigation and personalization options, including multiple filters that you can use to access your content. Content-usage filters such as “Recent,” “Shared,” and “Opened” help you find content based on your interactions, while content-type filters such as “Word,” “Excel,” and “PDF” make it easy to filter by file type. Users can personalize their home screen by adding, removing, or organizing these filters. To use Quick Access, just tap on any of the options at the top of the screen. To configure the default options, tap More; select + to add an option and to remove it.

PDF options are now accessible in the bottom bar

Working with PDFs is an important functionality in Office Mobile. Now you can conveniently access important PDF options from the + (create) button at the bottom of your Office Mobile screen. To access these options—including scan a PDF and convert to PDF (both pictures and documents)—tap the + icon, tap PDF, and then click on the option you want.

Continue listening to documents even when your screen is locked

Read Aloud takes advantage of the latest text-to-speech technology, enabling you to review your content “out loud” and catch any errors (also known as “proof-listening”). Using this feature on your Android is a great way to step away from the screen and give your eyes a break while listening to documents. Now we’ve added the capability for this feature to continue reading even after your device screen has locked. To use the feature, open a Word document on your device. Tap Review and then tap Read Aloud, or the Read Aloud icon (Read Aloud icon in Word for iPad) in the overflow menu. The app will begin reading the text wherever the cursor is placed and continues to read even after your lock screen comes on.

Easily turn off Dark Mode with one tap

Using Dark Mode is an extremely popular way to give your eyes a break from a bright screen. But we received a lot of feedback that users would like a way to quickly switch from a dark to a light background in their documents. Now you can! We’ve added a command that allows you to quickly turn off the dark background with one tap. To do so, just select the More options (triple dot) menu at the top-right corner and tap Switch to Light Background.

Record your thoughts using your voice with dictation feature

There are times when trying to type a note into your Android device is inconvenient—perhaps while you’re doing chores or working out. OneNote Mobile for Android now supports voice notes, allowing you to capture that thought without having to laboriously type it out. (Dictation has been shown to be as much as three times faster than typing.) To turn on this feature, open OneNote and click the mic icon at the bottom right of the screen. Start speaking and watch your words turn into text!

Office Mobile

Voice capture in Office Mobile apps

Now you can use your Android phone to capture voice recordings—such as quick thoughts, notes, or interviews—and then easily reference or work with both the audio and text transcripts.

The new feature allows you to go beyond simple voice memos, with live speech-to-text transcription. It also offers synced text highlighting during playback and the ability to share your content by exporting it to other Microsoft 365 apps and services. If you are a Microsoft 365 subscriber, this feature can also partition and transcribe the input from different speakers based on their identity (also known as speaker diarisation).

To try out the feature, open the Microsoft Office app on your Android device and tap the + button at the bottom of the home tab. Under Quick capture, tap Voice to launch the voice capture experience. Start speaking to record and tap the Done button when finished. To review your recording, select the voice card for playback with synced text highlighting.

Save time and increase accuracy with text predictions

Typing on your phone can be slow and, at times, difficult. Using text predictions, you can enter text more quickly and reduce the number of typos you make.

Text predictions will appear as faint gray text to the right of your cursor as you type. To accept these text predictions, simply swipe right anywhere on the screen. If you don’t like the suggestion, you can continue typing or swipe left. (Note that text predictions are enabled by default in Word Android and Office Mobile. You can turn this feature off by going to Settings (in the three-dot menu at the top right) and turn off Show text predictions while typing.)
