With Java OCR and just a few lines of code, you can create full-featured application that converts an TIFF image to XLS document:
- Create an instance of AsposeOcr class
- Call AsposeOCR.RecognizePage method
- Pass the TIFF file path as parameter
- AsposeOCR.RecognizePage returns a String or file of XLS type
System Requirements
Before running the example, make sure that Java 2 Platform, Standard Edition (J2SE) 6.0 (1.6) or later is installed on your system.
- JDK 1.6 or higher is installed.
//Create API instance
AsposeOCR api = new AsposeOCR();
//Prepare rectangles with texts.
ArrayList rectArray = new ArrayList();
rectArray.add(new Rectangle(138, 352, 2033, 537));
rectArray.add(new Rectangle(147, 890, 2033, 1157));
String result = api.RecognizePage("srcImage.png", rectArray);
System.out.println("Result with rect: " + result);
TIFF What is TIFF File Format
TIFF or TIF, Tagged Image File Format, represents raster images that are meant for usage on a variety of devices that comply with this file format standard. It is capable of describing bilevel, grayscale, palette-color and full-color image data in several color spaces. It supports lossy as well as lossless compression schemes to choose between space and time for applications using the format. The format is extensible and has underwent several revisions that allows the inclusion of an unlimited amount of private or special-purpose information. The format is not machine dependent and is free from bounds like processor, operating system, or file systems.

Files with XLS extension represent Excel Binary File Format. Such files can be created by Microsoft Excel as well as other similar spreadsheet programs such as OpenOffice Calc or Apple Numbers. File saved by Excel is known as Workbook where each workbook can have one or more worksheets. Data is stored and displayed to users in table format in worksheet and can span numeric values, text data, formulas, external data connections, images, and charts. Applications like Microsoft Excel lets you export workbook data to several different formats including PDF, CSV, XLSX, TXT, HTML, XPS, and several others. The XLS file format was replaced with a more open and structured format, XLSX, with the release of Microsoft Excel 2007. The latest versions still provide support for creating and reading XLS files, though XLSX is the first choice of use now.
