XLSX Document Format XLSX Converter
XLSX is a file type created using Microsoft Excel - part of the Microsoft Office Suite software. This file format is a zipped Open XML-based file type, meaning it compresses or reduces the file size so that it can access stored data faster and be easily shared with other programs. XLSX was developed by Microsoft as part of their Office 2007 development and is now the default file format for Excel.
XLSX files are very similar in their functionality to their predecessor, XLS; they can be used to create spreadsheets, charts and graphs, process mathematical formulae, and to share or analyse data. The main difference between XLSX and XLS is in how the data is stored. Whereas XLS files hold data in a single file, XLSX saves data in the Open XML format, with separate files zipped up together to reduce space. This also means that XLSX files can present larger data sets and have a greater range of cells. As well as with Microsoft Excel, XLSX files can be opened using various other programs, including Google Sheets, LibreOffice, and Apple Numbers.

The XLS file format was developed by Microsoft for its Excel spreadsheet program. XLS is a binary spreadsheet format that can include cell data and formulas, as well as charts and macros. Excel is one of the most popular software programs for recording, organising, calculating and analysing data. It’s often used for budgeting and reporting.
Microsoft introduced the new XLSX format for Excel in 2007, to replace XLS. However, you can still open XLS files in newer versions of Excel, as well as saving XLSX files into this older format. Excel is part of Microsoft’s Office suite, which is available as a one-off software purchase or an Office 365 subscription. Other spreadsheet programs that can usually open XLS files include Google Sheets, Apple Numbers and LibreOffice Calc.

They may look very similar as spreadsheets go, but XLS and XLSX aren’t the same. The main differences between the two are the file extension, size, performance, security and reliability. Although XLS is the format used for Excel 97-2003, these files can be opened in any version of Microsoft Excel. XLSX is a modernised version for Excel 2007 onward, but this file type can only be opened with newer versions of Excel. If you want to convert your XLSX file to XLS format, or vice versa, then the free conversion tool on Zamzar’s website makes it really easy.
You can convert XLSX to XLS in three quick steps using Zamzar’s online file converter. The conversion tool is web-based with a simple user-interface and converts files really quickly. Alternatively, if you have access to Microsoft Excel, you could use this to open your XLSX file and then save it as an XLS file.
If you have several files to convert, using Zamzar’s online tool will save you time compared to converting each file individually with Excel.
Depending on your needs, XLSX may be better for you than XLS. While XLS is usable in any version of Microsoft Excel, supports Macros, and works faster than XLSX, it does have limits to the amount of data it can store, and is less robust than the XLSX format. XLSX is widely compatible with non-Microsoft-based devices, but can only be opened on versions of Excel 2007 or later. It doesn’t support Macros, but it can save more data in smaller file sizes than XLS. If you need to convert your XLSX file to XLS format, you can easily do that with the free conversion tool on Zamzar’s website.
