Microsoft Excel up until 2007 version used a proprietary binary file format called Excel Binary File Format (.XLS) as its primary format. Excel 2007 uses Office Open XML (.XLSX) as its primary file format, an XML-based format that followed after a previous XML-based format called "XML Spreadsheet" ("XMLSS"), first introduced in Excel 2002. Although supporting and encouraging the use of new XML-based formats as replacements, Excel 2007 remained backwards-compatible with the traditional, binary formats.
This compressor only compresses images in Excel files, it can't minify Excel file which doesn't have images in it. We can't find any open-source projects to compress Excel spreadsheets, therefore we wrote all the source codes from scratch by ourselves. Your bug reports, comments or suggestions are welcome!
