Gnumeric has the ability to import and export data in several file formats, including CSV, Microsoft Excel, HTML, LaTeX, Lotus 1-2-3, OpenDocument and Quattro Pro; its native format is the Gnumeric file format (.gnm or .gnumeric), an XML file compressed with gzip. It includes all of the spreadsheet functions of the North American edition of Microsoft Excel and many functions unique to Gnumeric. Pivot tables and conditional formatting are not yet supported but are planned for future versions.
Gnumeric's accuracy has helped it to establish a niche among people using it for statistical analysis and other scientific tasks. For improving the accuracy of Gnumeric, the developers are cooperating with the R Project.
Gnumeric has a different interface for the creation and editing of graphs than the competing software. For editing a graph, Gnumeric displays a window where all the elements of the graph are listed. Other spreadsheet programs typically require the user to select the individual elements of the graph in the graph itself in order to edit them.
