The Free Excel Viewer is a small program that allows non-Microsoft Office users to view and edit Excel spreadsheets. It is a free, 4 MB download.

The software supports a variety of popular table file formats, such as XLSX, XLS, XLSB, ODS, CSV, and XML. Beyond simply opening and viewing Excel workbooks and other table formats, Free Excel Viewer provides robust editing tools that allow users to edit tables and cells just as they would with MS Excel.
I was especially impressed by the export and conversion options of Free Excel Viewer. In addition to saving the opened Excel file as an XLSX format, users can export and convert Excel files to PDF, HTML, ODS, XPS, SVG, and XML formats.
Free Excel Viewer comes in both an EXE installer version and a portable ZIP version. The portable version is particularly useful as it allows users to use the viewer anywhere without having to install it on their computer.
The software's tiny file size, at only 3.4 MB, is also a plus. It is user-friendly and is available in multiple languages.
Overall, I found Free Excel Viewer to be an excellent option for users who need a robust and easy-to-use Excel viewer and editor without having to purchase the full version of MS Excel.
