How Microsoft's Office app helps with schoolwork, PDFs, signatures and more

Fill out worksheets, sign permission slips, make PDFs and more, all from your phone.

Microsoft launched its Office app for iOS and Android in February, a few weeks before the pandemic drove us all indoors. Who knew, as my family hunkered down to work and study from home, that the Office app would quickly turn into an indispensable tool for managing day-to-day document tasks for my kids as well as myself. If you don’t know how much it can do, keep reading to find out.

If it is or could be a document, Office can help

We’ve used the Office app on Android, and it allows you some frankly amazing flexibility. You can take a picture of a page of a book and use the Office app to extract the text automatically using optical character recognition. You can turn a photo into a PDF. You can sign a PDF that you’ve already created. You can take a photo of a spreadsheet and turn that into an Excel table, or turn a document into a PDF, or vice versa. Don’t underestimate those last features, either, as PDF-to-Word conversion tools can be hard to come by. And, of course, unlike most of the PDF editors we’re reviewed, all these Office app functions are free.

Use the Office app to turn in your kids’ homework

If you and your child are tired of fighting with Google Classroom, drawing apps, and the like, you probably want to know how your child can work on paper—you know, like we all used to do? Microsoft’s Office app for Android offers a way back to the good old days.

If you have the ability to print out a worksheet, your child can mark it up with a pen or pencil. Then, you can scan it in and either upload it to your child’s online space or email it directly to a teacher—provided that the software and the teacher allow for it, of course. (We can’t do anything about the last bit.)

Microsoft’s Office app for Android stores a list of your frequently-accessed Office documents, but its list of powerful tools are hidden within the “Actions” menu.

How to ‘scan’ schoolwork using the Office app

Your child’s teacher has probably already told you one way of entering hand-drawn work: using the camera on the PC or Chromebook. At our school, the students are asked to open their Google Doc, navigate to the “Insert Image” icon on the toolbar, and snap a photo from the user-facing camera. It’s easy, effective, but not always that clear.

If you’d like, you can use the mobile Office app to do the same thing, and it will look nicer. Open the Office app on Android, and navigate to the Actions icon at the bottom of the screen.

The Office app’s Actions menu.

You’ll see a whole list of interesting menu items. Click Scan to PDF, a somewhat confusing name. 

This will bring you to a pretty conventional photo screen with some interesting options at the bottom. By default, “Document” is highlighted. If you place your child’s worksheet on a table or bed, you’ll see a small ghostly rectangle surrounding it. This is the Office app’s AI magic at work: It will sense the document’s borders and align them so that your PDF will look nice and neat. In other words, don’t spend a lot of time aligning the document’s borders within the frame, as the app will do it for you.

The Office app may be hypersensitive to boxes drawn on the page—it will sometimes think that a box, such as the middle one, is the entirety of the page. Note the “stacked photos” icon to the lower left: You can use that to make a multi-page PDF using multiple images.

Choosing the “whiteboard” option allows you to take a photo of a piece of artwork that’s hanging on the wall—and again, Office will make it nice and neat. Office will save the file as a PDF, and it will be accessible from the main screen.

If you look closely, you can see how the Office app has extracted the artwork from the rest of the scene.

Office does have an option to turn an existing photo (from your camera roll) into a PDF, but all it does is turn the image into a PDF, with none of the AI snipping that the app otherwise offers. I find it’s simply more effective to snap a new shot if the original document is available. 

How to sign a PDF from your phone

If your child receives a permission slip either in email or in person, and you want to send it back electronically, the Office app makes this easy, too.

Do you have a printed document? Use the “scan to PDF” function above, to turn it into a PDF document.

Do you have an electronic document, such as a Word or Google Docs file? If it’s a Google Docs file, save it in Word. Word files can be opened with the Document to PDF conversion tool, which is part of the mobile Office app you’re using. 

Once you have a PDF of your file, you should see a Sign a PDF option in the Actions heading, under the Do more with PDFs subheading.

The app will open your PDF, and you’ll select an approximate spot to add a signature. Don’t worry if the location’s not precise. Once you’ve tapped the location, an entirely different window will open, where you can add your signature. You can save your signature as well.

The Sign with PDF tool allows you ample space to input your signature, as well as the option to save it.

Once you’ve entered your signature, the PDF will reopen again, with a mammoth overlay of your signature superimposed upon it. Pinch and zoom the signature to shrink and fit it to the space, then save the PDF.

You then have the option to resize and move the signature as you’d like.

How to send a PDF from the Office app

The Office app’s main screen allows you to share a document (via text or email), including the PDFs you just created. But what if you need to move the file to your computer, or your child’s computer, to upload it? Again, the Office app has anticipated that.

The Office app will direct you to this intermediary site to facilitate sending files between your phone and your computer. You’re free to use email or another app, too.

The Transfer Files option at the top of the Actions page will direct you to transfer.office.com, a website where you’ll be asked to scan a code with your phone to authenticate a transfer. Because it’s web-based, you should be able to transfer the PDF regardless of whether the laptop is a Chromebook or a Windows PC. On your phone, you’ll need to select Send or Receive to make sure the file is going in the right direction. Find the file in File Explorer and save it where it needs to be.

How to use your phone as an OCR to scan text

There’s another fun trick that may benefit older kids working from a printed textbook who need to take notes: Turn your phone into an OCR (optical character recognition) device. We’re not scanning a page as your scanner would—we’re reading and copying the text on the page.

Microsoft’s “Image to Text” in action within the Office mobile app, transcribing a page from Walter Isaacson’s biography of Steve Jobs.

To begin the process, go to the Actions page once again and select the Image to text option. This will work on a live photo or a stored image. 

Office does this fairly well, though you’ll always want to proofread it. You’ll get better results if the page is flat and well-lit.

We’re all trying to manage the pandemic, working from home, and distance learning if we have school-age kids. Microsoft’s Office app for Android and iOS is a handy way to save a little time and effort. Use it!

As the Maserati or BMW of laptops, it would fit perfectly in the hands of a professional needing firepower under the hood, sophistication and class on the surface, and gaming prowess (sports mode if you will) in between.
