The differences between xls and xlsx in excel are: 1. xls is a binary file format, while xlsx is an XML-based file format; 2. xls can still be opened and edited in newer Excel versions, while xlsx It can only be opened and edited in newer Excel versions; 3. xls does not support some newer functions and features, while xlsx supports more functions and features; 4. xls data is relatively easy to be infected by viruses or malware, and xlsx data is relatively more secure.
Excel is a spreadsheet software developed by Microsoft and is widely used in data analysis, statistics, financial management and other fields. In Excel, there are two common file formats, namely xls and xlsx. There are some differences between the two formats, detailed below.
First of all, xls is an early file format of Excel. It is a binary file format and stores data in binary. xlsx is a newer file format of Excel. It is an XML-based file format that stores data in XML. These are two completely different file formats, so there are some obvious differences between them.
The first difference is the file size. Since xls is a binary file format, it uses binary encoding when storing data, so the file size is larger. xlsx is an XML-based file format that uses text encoding to store data, so the file size is relatively small. This means that xlsx format files take up less disk space when storing large amounts of data.
The second difference is compatibility. Since xls is an earlier file format of Excel, it can still be opened and edited in newer Excel versions. However, xlsx is a newer file format and can only be opened and edited in newer Excel versions. If you are using an older version of Excel, you may not be able to open or edit files in xlsx format. Therefore, you need to consider file compatibility when choosing a file format.
The third difference is functional support. Since xls is an earlier file format of Excel, it may not support some newer functions and features. Xlsx is a newer file format that supports more functions and features, such as conditional formatting, pivot tables, charts, etc. If you need to use newer Excel functions, it is recommended to use xlsx format files.
The fourth difference is data security. Since XLS is a binary file format, its data is relatively easy to be infected by viruses or malware. And xlsx is an XML-based file format, and its data is relatively safer. Therefore, if you have higher requirements for data security, it is recommended to use xlsx format files.
To sum up, xls and xlsx are two different file formats in Excel. XLS is an early binary file format with large file size and good compatibility, but its functional support and data security are relatively low. xlsx is a newer XML-based file format with smaller file size, higher function support and data security, but relatively poor compatibility. When choosing a file format, you need to choose based on your specific needs .
