XLSX is an electronic file format that uses the OpenXML standard, which was developed by Microsoft and widely used in its Excel software. XLSX files can store various types of data, including numbers, text, formulas, and formatting, and it can also contain charts, images, and more. Compared with earlier Excel file formats such as XLS, XLSX has higher storage efficiency and stronger data recovery capabilities.
1. Properties of the xlsx file.
1.Compressibility: An xlsx file is actually a zip archive that contains multiple files and folders. These files and folders store various electronic components in XML format, such as worksheets, styles, charts, etc. Due to the compression technique, XLSX files are typically smaller than earlier binary excel files such as XLS.
2.Openness: XLSX is based on the OpenXML standard, which means that its format is public and can be parsed and used by any third-party software. This openness promotes interoperability with other applications and systems.
3.Extensibility: Due to the flexibility of XML, XLSX files can be easily added with new features and functionality without changing existing file formats. This allows Excel to be continuously updated and improved while maintaining compatibility with older versions of files.
4.Security: XLSX supports stronger encryption technology to protect file content from unauthorized user access. In addition, since the file format is open, security vulnerabilities can be more easily identified and fixed.
2. Other file formats and their attributes.
In addition to XLSX, there are several other common formats for electron**, each with its own unique properties and uses.
1.XLS: This is an early file format for Excel that stores data in a binary format. XLS files are usually larger than XLSX and do not support some new features. But due to its wide compatibility and long history of use, the XLS format is still widely used.
2.CSV (Comma-Separated Values): This is a simple text format that stores data. In the CSV file, each row represents a record, and each field is separated by a comma. The versatility of this format makes it easy to share data between different applications and platforms. However, CSV does not support complex formats and formulas, and the data is usually stored in plain text.
3.ODS: This is the format of OpenDocument Electronic**, as defined by the Open Document Format (ODF) standard. ODS is an open, XML-based format designed to provide interoperability across multiple applications and platforms. Similar to XLSX, ODS supports a rich set of features and formats, but due to its open nature, it can be used in a wide range of open-source and commercial software.
4.Google Sheets: Google Sheets is part of Google Drive, and it uses its own electronic format. This format makes it easy to collaborate on editing and sharing data on the web. Google Sheets can be exported to XLSX, XLS, CSV, and other formats to ensure compatibility with desktop applications.
Summary. There are many different electronic file formats, each with its own specific benefits and use cases. As the standard format of modern Excel, XLSX is popular for its efficiency, openness, and security. At the same time, other formats such as XLS, CSV, ODS, and Google Sheets also play an important role in specific contexts due to their unique properties. Understanding the properties and differences of these formats helps users choose the right tools for data processing and analysis according to their needs.
