XLS (Excel Spreadsheet) is a file format used to store tabular data, such as spreadsheets and tables. It was introduced in the early 1980s by Microsoft as an extension of the XLSX file format. Today, it remains one of the most popular file formats for storing data and information. The XLS file format stores data in a table-like structure, with each row representing a single record or entry. Each column represents a field or attribute within that record, and can contain numerical, textual, or date/time data. The size of an XLS file depends on the amount of data it contains, but it is generally smaller than other file formats such as CSV or JSON. One of the main advantages of XLS files is their compatibility with a wide range of software and devices. Because they are such an old format, XLS files can be opened and edited on almost any computer, regardless of its operating system or software capabilities.
