The Saaspose file format APIs have been designed to manipulate and process the documents in cloud across any platform. Saaspose APIs offer to work with MS Word documents, presentations, worksheets, images, barcode, etc. There might be a scenario where developers want to convert workbook elements to images using Saaspose.Cells and extract text from the images using Saaspose.OCR. Saaspose.Cells is a REST API that helps you create, manipulate and convert spreadsheets in the cloud whereas Saaspose.OCR is a REST API for optical character recognition and document scanning. Let’s have a look at how you can use these two REST APIs together to work with spreadsheets and text recognition. A workbook may contain a variety of objects such as auto shapes, charts, ole objects, pictures, etc. You can convert auto shape to image using Saaspose.Cells in your applications. This feature-rich API allows you to convert different charts in a workbook to images. You may choose to convert a single chart or all charts to images. Similarly, you can convert ole object in a workbook to image and convert the pictures to images as well. An ole object may contain different types of external objects and Saaspose.Cells supports the conversion of such objects to images in no time. Also, you can convert a whole worksheet to image using Saaspose.Cells REST API. Once you have performed conversion of workbook elements to images, you can use Saaspose.OCR REST API to recognize text from images and save it to the database. Saaspose.OCR supports a variety of fonts in different styles, like regular, bold, and italic, and different image formats. Saaspose.Cells eliminates the need of any complex operations involved in manipulating the workbooks or working with various elements of a worksheet. Conversion of worksheet objects to images is a significant aspect of worksheets and formatting is not compromised during the conversion to image.
