This ED OCR tool monitors your screenshots folder and outputs a csv file to your documents folder. It uses Tesseract OCR and needs minimal setup and intervention. It does not contain a dictionary, so some screening might be necessary when importing data.
Comment: This was a quick 2 day project, I would suggest using it as an alternative to some of the other well maintained tools. When needed I will make the source code available.
Source code is now available on GitHub.
