ODS is a spreadsheet received using StarOffice, OpenOffice, and other office suite programs. This table is created in the Calc application, and it is part of the free Apache OpenOffice office suite. An ODS file (Open Document Spreadsheet) stores all the data in cells, which are rows and columns. He is able to additionally have text, graphic elements, diagrams. Note that the ODS format is not always tables. It also happens that this is a mailbox or archive for electronic messages. Then it is created or saved in Outlook Express. The file format is based on OASIS, which is an open document format for office applications. All file data is in the form of XML. The OpenDocument standard can be used by everyone. And there are no restrictions. The ODS format is unlimited for any office application. Its source code is open, that is, it is a good alternative to Microsoft's proprietary format (.xls). Those who choose Microsoft Office will not need conversions. Excel in the 2007 version, which includes the second service pack, is able to support this format. To adapt such a document with an earlier version of the spreadsheet editor, the Sun ODF plug-in is installed.
XLSX is a more modern version of the spreadsheet format, a type of e-book within the Microsoft Office Excel suite. It takes its name from the Microsoft Excel Open XML Document. This format has replaced the XLS. Initially included in the paid package of MS Office, but then the Open XML standard was recognized as public. As in XLS, the data is placed in the cells of the table, however, it uses data compression like ZIP. This reduces file size and increases the potential for data security. Data can be entered into the cells manually, as well as by automatic calculations - when special formulas are entered into the cells, starting with the equal sign.
