What is LibreOffice Calc?
The Libre Office Calc is the spreadsheet application of the Libre Office productivity suite, and is analogous to Microsoft Office’s Excel and the Lotus 1-2-3, the first of its kind; the Libre Office Calc has comparable features and capabilities. It can also support other spreadsheet file formats, like .xls, .xlsx, .csv, HTML, among others, and can directly create a PDF file from a spreadsheet, and can natively support Open Office Calc spreadsheet files.
Just as Open Office is an alternative to Microsoft Office (and Corel's Office applications, to a lesser extent), Libre Office fulfills the same role to Open Office. Forked from Oracle's Open Office suite, Libre Office is essentially the same, with a few subtle improvements that those who use either may not be able to spot unless they are specifically looking for something (for example, Libre Office supports more languages than Open Office). Although Open office still is free (with Oracle offering a commercial, paid version of the software with added features like technical support), Libre Office retains the original Open Office (which was first named StarOffice) philosophy of being open and free; to this end, Libre Office is both free and open-source, with its code base being written and expounded upon by its community.
