Grab It! for Excel enables you to get digitized data from images. It lets you use Excel to include a photograph or chart, for example, and determine measurements or data. Uses include extracting data from scientific publications, scaled photographs, and stock market charts. Simply choose the types of X and Y axes, choose a graph type, and select from numeric, scientific, date, time, and general X and Y output. Enter boundaries, and as you select points, their data is inserted into the open Excel spreadsheet. Excellent instructions are included. Grab It! for Excel is an easy-to-use system that eliminates guesswork when it comes to obtaining precise data.
 

"Grab it!", a product of Datatrend Software, is a PC based utility designed for data extraction from electronic graphical images.  Conveniently interfacible with Microsoft Excel, it allows data from the image to be directly incorporated into the spreadsheet for further manipulation.

Via a simple point and click elucidation, "Grab it!" can extract numerical information from graphical images in a wide variety of commonly used graphical formats, including typical Web files such as JPEG and GIF.  Given the importance of the Web as an information dissemination medium, this provides a useful tool to the scientist or engineer interested in quantifying graphically displayed data.  Armed with a scanner, this functionality can be extended to hard-copy images.

One current limitation of the software is accuracy and precision in that it relies on the user to pinpoint the location of the data points on a screen of only finite resolution.  As a recommendation for refinement of this concept, it might be useful to consider incorporation of image recognition and processing techniques to enhance the precision and accuracy of the data extraction process.
