Convert XLS to PDF

.xls

Microsoft Office

XLS – is a spreadsheet created by a popular Microsoft Excel application. It includes document data that is located in cells that have a specific address. They can contain formulas, mathematical equations associated with the information in other cells, and fixed information. It is often used for the development of graphs and charts. The format allows us to store and edit a broad range of parameters - images, tables, macros, types, diagrams. It has been widely used until the appearance of the 2007 version of Excel, and then it was replaced with the XMLSS extension. The information inside the XLS document is contained in a series of static-size streams. Their location is described using several segment distribution tables. It differs in backward compatibility and supports various file formats created for DOS. It is often used by web browsers to exclude the use of binary formats. The utility is included in the Microsoft Office suite and, in addition to Excel, can be opened by various applications like Apache Open Office, Libre Office, adapted to Mac OS, Windows, or Linux.

The format's relevance is explained by its simplicity, although it does not support separate functions, for example, storing VBA macros. Until XMLSS appeared, the Excel application used the Biff extension when formatting, created based on the IFF container format. Due to this, changes to the book templates and their contents were available. After introducing the new format in 2007, the program has not lost the backward compatible properties, which guarantees the wide distribution of XLS in the future. Subsequently, the XLS extension was replaced by the XLSM, XLSB, and XLSX formats.

.pdf

Adobe Viewer

PDF – is a cross-platform extension necessary for the visualization of printed materials in electronic form. It is developed by Adobe Systems using separate PostScript resources. PDF documents can exist separately from the OS or hardware tools with which they were developed. Files of this format do not have restrictions on the length, several types, and image options, as they allow you to embed various multimedia tools, scan-line, and vector images. They are supported by Adobe Reader and many browsers, providing the plugin is installed.

PDF supports color models CMYK, RGB, shades of gray, and also it has its technical formats for performing the exchange of finished documents. Any file contains a description of a 2D or 3D document with all the necessary components (scan-line, vector graphics, text, and more). The extension does not encode data associated with the software or OS used to develop and view it.
