XLSX file format information

Full NameMicrosoft Excel Spreadsheet
Mime Typeapplication/vnd.openxmlformats-officedocument.spreadsheetml.sheet

An XLSX file is a type of electronic spreadsheet format commonly used to store data and perform calculations in software applications like Microsoft Excel, Google Sheets, and other spreadsheet software. The "XLSX" extension stands for "XML Spreadsheet." Unlike its predecessor, the older XLS format, XLSX files utilize the XML (Extensible Markup Language) structure, which makes them more versatile and easier to process programmatically. XLSX files can contain multiple sheets, each comprising rows and columns of cells, with the ability to store text, numbers, dates, formulas, charts, and other data elements.

The XML-based structure of XLSX files offers several advantages, including smaller file sizes, improved data recovery options, and better compatibility with various software platforms. Moreover, XLSX files enable users to apply formatting styles, apply formulas to manipulate data, and create graphs and charts to visualize the information. They are widely used in business, finance, education, and research sectors, allowing users to organize, analyze, and share data efficiently in a structured and visually appealing manner.

Due to its widespread adoption and support by popular spreadsheet software, the XLSX format has become a standard for sharing data across different systems and applications. Additionally, the format supports macros, which are sequences of instructions that automate repetitive tasks, further enhancing productivity and streamlining workflows. Whether it's managing financial data, conducting data analysis, or organizing lists, XLSX files serve as an essential tool for businesses and individuals seeking an organized and efficient way to handle data and perform calculations.
