Data journalism is a meticulous job. Mistakes are not allowed. A single number changes, and we can fall into reporting false data and miscalculations.

Although fact-checking is indispensable, there are other types of tools that can help us copy the exact information from a document, trying to minimize as much as possible the errors of passing data by hand.

One of the tasks that data journalists must perform is to convert closed data, where the specifications are not publicly available because the format is not accessible or because its reuse is limited, into open data, which are available to anyone, free of charge and without any limitation.

For this, there is a procedure called Optical Character Recognition (OCR). According to Wikipedia’s definition, it is used to digitize texts, automatically identified from an image, symbols, or characters belonging to a certain alphabet and then stored as data. In this way, it is possible to interact with such data through an editing program or similar.
