What is the difference between xls and xlsx

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 can only be opened and edited in newer Excel versions. Open and edit in Excel version; 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, while xlsx data is relatively safer.

The difference between xls and xlsx: 1. File structure, xls is an early binary file format of Excel, while xlsx uses an XML-based file structure to store data; 2. File size, xls files are larger, and xlsx is based on XML, so the file Smaller; 3. Compatibility, xlsx is more compatible with other programs and versions than xls; 4. Function, xls has some limitations in functionality, while xlsx provides more functions and flexibility; 5. Security, xls may have security risks, xlsx does not.

Use nmap-converter to convert nmap scan result XML to XLS. Practical 1. Introduction As a network security practitioner, sometimes you need to use the port scanning tool nmap to perform large-volume port scanning, but the output results of Nmap are .nmap, .xml and .gnmap The three formats are mixed with a lot of unnecessary information, which is very inconvenient to process. The output results are converted into Excel tables to process the later output. Therefore, a technical expert shared a Python script to convert nmap reports to XLS. 2. nmap-converter1) Project address: https://github.com/mrschyte/nmap-

The difference between xls and xlsx: 1. File structure, XLS files are stored in binary format, while XLSX files are based on the XML file format of the open document standard, and the data is stored in a hierarchical structure; 2. File size, since When stored in binary format, the file size is relatively large, while XLSX files use a more efficient compression algorithm, and the file size is usually much smaller than the XLS format; 3. Compatibility and interoperability; 4. Function and compatibility.

1. XLS is a common spreadsheet file format commonly used to store and process data. 2. It is one of the default file formats of Microsoft Excel and is also supported by many other spreadsheet software. 3. The xls file stores data in binary form and can contain multiple worksheets.
