If you had a picture of someone's spreadsheet, you could type it into Excel yourself - you can't fit huge amounts of data into a single photo. Microsoft's tool would only save you a few minutes worth of typing. For that matter, if you just get a glimpse of someone's spreadsheet, you could see something you weren't supposed to see and remember it. That's why people who work with sensitive data shouldn't be working in open-plan offices or coffee shops.
