Have you ever wondered how to calculate important data, such as ratings, financial forecasts, or any other numeric information, if it is in a photo or a raster image format? It happens that we need to take some pictures of a table on a whiteboard or scan old catalogs and records for further statistical research. For example, a long time ago I worked with a local firm and did a basic financial analysis of its business activity. Since there were no digital records and scanners in the office, I was forced to take photos of balance sheets and retype them to Excel manually. After a few weeks of struggling, I found a suitable way of converting an image to .xls, and it saved me 80% of the time. Luckily, nowadays, a plethora of options have become available.
