Description Microsoft Excel 1997-2003 is the name of the file type created by four different releases of Microsoft Excel. The release of Microsoft Excel 97 was a major leap forward in terms of functionality and usability compared to the previous version, Excel 95. Excel 2000, Excel XP and Excel 2003 all followed featuring tweaks to the appearance and functionality however the core application remained consistent. It was during this period that computers became incredibly popular for both personal and business use resulting in Excel becoming the de facto spreadsheet application. Excel provided functionality to a basic user with a requirement to store data in an organised fashion up to advanced users requiring formulas, charts and pivot tables.

Technical Details XLSX improves file and data management and data recovery. XLSX extends what is possible with the binary files of earlier versions. Any application that supports XML can access and work with data in the new file format. The application does not need to be a Microsoft product it can be any application. Users can also use standard transformations to extract or repurpose the data. In addition, security concerns are drastically reduced because the information is stored in XML, which is essentially plain text. Thus, the data can pass through corporate firewalls without hindrance.
