I am afraid, your query is out of context. Aspose.Cells for Java is a class library used to create, manipulate, render, convert or print MS Excel spreadsheets (e.g XLS, XLSX, XLSM, CSV, Tab, delimited, SpreadsheetML (.xml), etc.) or other file formats, e.g SVG, ODS, PDF, etc. It supports almost all the features which MS Excel (97-2010, 2013) supports. In short, Aspose.Cells works on MS Excel file formats and does not work, depend or have any links to MS Excel. The Excel files generated by the component can be opened by MS Excel or any Excel viewer application.
