Yes, Office Lens is great for that. I recently switched to CamScanner, which has an even better algorithm for deskewing pages (take a pic of a receipt at an odd angle, it automatically transforms it to flat and rectangular). Pro version was on sale -- I'm not affiliated, just a happy customer and highly related to this article.

I have it as well, but use Office Lens or Google Drive (create a shortcut to a folder on home screen of android device and use it to scan into it).

The reason is CamScanner tried to upsell me to some monthly plan.

For all good advice on HN that you should build recurring revenue: It seriously annoys me when people tries to do that by demanding monthly payments for static features.

(Totally OK with selling license keys for new features etc.)

Update: CamScanner is now less annoying than what I used to remember. I might actually be switching back.
