What you need is called OCR (Optical Character Recognition) and can be done with a few apps like ABBYY FineReader. The software is capable of scanning an image and then export it to a supported document. Most scanners have this feature already built-in, but if you don't have a scanner, then you can use the above application.
You can use it as a trial for a limited period of time, then you need to buy it to unlock its full features: https://www.abbyy.com/finereader/
