MS Excel 2007 XML to JFI conversion is the process of transforming a workbook saved in the XLSX format (the Office Open XML format introduced with Excel 2007) into a JFI document file. This conversion extracts spreadsheet data, structure, and common formatting from the XLSX package and re-encodes it into the JFI format so the content can be opened or processed by software that supports JFI.
