The OneDrive app for Apple iOS devices now lets you create Word, Excel and PowerPoint documents directly.
A small change but handy if you’re in the OneDrive app already. Tap the + icon at top left, then choose the type of document you want to make. The appropriate app will open with a blank document.
From the app you can save to any available location, not just OneDrive. The button in OneDrive is just a gateway to the Office app.
Of course, if you want to open an existing document from OneDrive, tap on it to open in the correct Office app,
