Opening DEX files

What is a DEX file?

The .dex file extension is used for a workbook or spreadsheet file format that was developed by Microsoft. These DEX files are normally found in Windows PCs where older versions of Microsoft Excel is installed. A .dex file can be created using these outdated Microsoft Excel versions.A DEX file may contain formulas, equations, calculations, text, numbers and formatting attributes that are usually found in other spreadsheet documents created using Microsoft Excel. This software is a popular spreadsheet application, and its more recent versions use the XLS file format for its default spreadsheet output files, while the newest Microsoft Excel versions, starting with MS Excel 2007, use the XLSX file format for its default spreadsheet output files.These .dex files can be opened and viewed using both old and new versions of Microsoft Excel. This software can also be used to edit the content of a DEX file and export it to a more recent file format like XLS or XLSX.
