Claim 16:
17. A computer program product, comprising a computer readable hardware storage device storing a computer readable program code, the computer readable program code comprising an algorithm that when executed by a computer processor of a computing system implements a method comprising:
determining, by the processor, a key position of a key in an electronic file;
isolating, by the processor, candidate key values based on a distance from the key position measured in at least three directions, wherein the isolating includes:
searching for candidate bounding boxes that contain the candidate key values based on the distance from the key position, and
filtering the candidate bounding boxes based on a relative position of a candidate bounding box with respect to the key position and other candidate bounding boxes;

selecting, by the processor, a key value from the candidate key values based on an output of a trained neural network; and
extracting, by the processor, the key and the key value from the electronic file.
